- I got my hands on the Raspberry Pi Zero 2 W. It's more than twice as fast as the original Pi Zero and Pi Zero W, but what other secrets does it hold?
I X-rayed it to find out what's inside this little Pi! It's not cheap making these videos, so if you like them, please consider supporting this channel:

Lol true story
I know this advice doesn't help most people, but for those living in the UK and are willing to go to Cambridge the official Raspberry Pi shop seems to have a stockpile. Accidentally found it when visiting a month or so ago and was surprised to see stock, they do limit how many you can purchase though.
@@Jonny5a hmm, a 34,000km round trip for a $15 SBC... Why not 😂
One week ago I was looking at zero wh board sold at 50 USD and it was sold out, then they announced a 15 USD zero2
me too
lol
9:51 A wild Chris appears! I love it when tech TH-camrs support and reference each other. Such a healthy community.
Also, that impression at 11:43 🤣
so funny lol
This will fit perfectly for purposes where ESP32 doesn't cut it (you need a general purpose OS for flexibility in your project), and a full Raspberry Pi is an overkill (either from compute or cost perspective). For e.g. as an infra/SRE guy, I want to use half a dozen of Pi Zero 2 to drive (old/salvaged) LCD screens all around my home to display various dashboards & notifications, so I can spend time with my family better without having to constantly check my phone or run to desk intermittently to check for incidents.
If I can actually get my hand on any of those, that is...
how would economically get a salvaged LCD screen connected to it though?
assuming there is no composite or HDMI in
@@andreamitchell4758the LCD interface has a spi port plus a video interface such as LVDS, RGB, or eDP. It wouldn't be *too* complicated to go from hdmi to one of those. Probably would need a custom PCB.
To me, this is just highlighting how late the release version of 64bit RasPiOS is! Now there is even a Zero-sized board that could benefit from it (with care about RAM usage).
I'm hopeful the 64-bit Pi OS build will become the default sooner or later. The Zero is the last of the boards that didn't have proper 64-bit support...
@@JeffGeerling That’s because the old Zero was an ARM 7 32-bit chip incapable of running modern ARM instructions. That’s been a huge challenge trying to find software that’s still buildable and functional on such an old instruction set, even if I pulled 32-bit compiles. To get Docker containers working, I pretty much had to run HyperiotOS as the only option. And then there were only a handful of software packages that worked, mostly compiled by Hyperiot. Once I found a working JVM I could run Java software. But that was painful on a CPU that underpowered. So this upgrade was long overdue as the old hardware was quickly growing useless.
@@thewiirocks ..”the old hardware was quickly growing useless “ to YOU, mayhaps…
But there are plenty of us out here that are running use cases (power budget) that run FINE on the “old, useless “ hardware.
Software has been written, and validated.
Now, having NEW hardware at the same price point AND power budget… then yes, it’s gonna be an easy (easier?) upgrade path,,,
And making the case for the ‘old’ hardware more difficult to support…
ARM7 to ARM8 is a major stepping stone in terms of software support.
You, Explaining Computers and ETAPrime all announced the board at the same time lol. Can't wait to get one
All three great videos too. Just wish Mr. Scissors could've make an appearance :)
@@JeffGeerling Mr. Scissors is always in our hearts.
And Novaspirit.
Does everyone have same recommendations on TH-cam!!😂
You missed Novaspirit Tech he also announced at the same time
ETA prime got it stable at 1.3 with heat sink. Can’t wait to buy a few of these 😄
That's awesome! Raspberry Pi and Framework are basically the only technology companies I can genuinely get excited about right now, so it's awesome seeing them continue to throw everything they have at their mission statement.
Jeff, I like your channel very much. I also like EC's. I'm very glad to see you give him a mention in support. Glad to see you reinforce another rather than compete against.
Love your bloopers Jeff! Thanks for adding them.
This is great! I love the Pi 0W for low-power projects that need more than a microcontroller. The 02W's extra power will be great for some of my projects that need just a little more oomph improve responsiveness.
Nice job on the x-ray microscope images, I have a GE Nanomex at work that we use for failure analysis, it's amazing how useful that kind of detailed imaging of the internal structure of a PCB can be.
I'd love to have more access to one... it costs a bit to get time on the one I used!
A new Pi Zero, yes!
Also a (somewhat custom CPU) I see hints to the Raspberry Pi 5 or 6 having an in-house CPU design, with a bunch of features.
Think that’s the one given now the Pi Zero 2 has a custom in-house SOC.
Still hoping they make a more daring choice to produce a “pro” Pi 5 with a different footprint, maybe up to the size of the CM4 I/O board to allow more headroom for advanced features.
@@stephenvalente3296 RPi5 model C?
You Were Correct, There's A New Raspberry Pi 5 With An Inhouse CPU !
I am a big fan of your content. Your approach settles well with me. Thank you very much!
I am so excited to get my hands on one of these. My original Zero W's are still going 3 years strong outside in the Florida heat!
I always learn so much from your videos. I just bought a Zero 2 W from Adafruit while they are in stock and 1 to a customer. Here today, gone tomorrow, I'm sure.
Hi from the UK, another great video Jeff. Knowing it can run 64 bit is incredibly useful. I run either Ubuntu (64 bit only) or Raspberry Pi OS 32 64 bit on my Pi 4Bs depending on the use case. The 512 MB RAM is likely to be a limiting factor but in time hopefully falling memory prices will give us a 1 GB version. For £13.50 at the Pi Hut in the UK it is priced cheaply enough that it can be bought to just ‘play with’. Looking forward to the next video.
I really love the bloopers at the end. Keep up the good work.
Thanks for taking power measurements! I gotta get my hands on one of these; I use a Pi Zero to drive one of the HQ cameras in an astrophotography setup (with some complicated USB network trickery to connect it to the main Pi 4 running the whole setup) and download/transfer times for each long exposure are pretty atrocious on the original Zero. A beefed up CPU would probably really help here!
Can't wait for your next video regarding the handheld!
Much love to Jeff and Red-Shirt Jeff. Allways love the content and get a big kick from the outtakes.
This is the only channel where I click the thumbs up button before watching the video - well done as always Jeff
LOL... Dude I love love love your channel. Great 👍🏾 man. I've watched this a few times now and I just love how down to earth and real you are.
I remember the Amiga 100 had signatures of Jay Miner, Dave Dean and the paw print of Miner's dog on the inside of the case.
A great tradition!
I just ordered 2 of these, I’m excited to play around with it soon.
Managed to order one right away this morning in the UK. Can't wait!
This is so cool. Thank you for taking a look at power consumption. :)
i have an 8 gig pi4 and i wanted a pi zero for a while now. I have ordered my pi zero2 online and in Hungary it was ~17 USD +VAT. I am happy that these are available in such a small country on launch day! Big thumbs up for that for the retail network : )
A magazine said that they are sending joke Pi's to Hungary where the speed will go to 5 ghz and then you fart
Heh. Your channel and Explaining Computers channel - along with ETA Prime's channel of course - are the only TH-cam channels I watch regarding anything microcontroller.
You for the clustering/Pi-based stuff, ETA Prime for the microcontroller gaming stuffs, and Chris at Explaining Computers because he's got a comfy feel like I'm watching a BBC educational program from the 80s.
I'm lucky that the Overland Park, KS Microcenter is about 2 miles from my house but they're always sold out of the Raspberry Pi 8GB I want.
The STL Micro Center has only had the 8 GB model in stock for months (though sometimes none in stock), I've been trying to get another 2 GB model :P
Dont know why but I love thee videos. You got yourself a sub, keep it up!
Ordered one the moment it was available. Not as interesting as the Pico, but still, $15 for a reasonably powerful computer messes with my 8-bit brain.
Good job with the x-ray. I bet they thought it might take longer for that one to be discovered.
great, never heard about the channel, but subscribed as I am sub of computers explained.
well done and explained.
Woke to yours and @ExplainingComputers new videos on the new RPi0w-2 this morning. Best day in a while.
Another video from Explaining Computers... dot com!
Sweet video man, love it! Very interesting
Hello Jeff, nice video as usual! :)
I paused mid video to order one, should be shipped soon :)
I like that with the raspi foundation, you don't expect anything, then boom! new board! However, it is becoming more expensive and difficult to try to "catch em' all"...
anyways, that is a great new board, will be perfect for HQ cam builds!
In order to compare efficiency, it would be interesting to compare the energy used for a fixed compute task.
For instance, transcoding a X Gb file on both, and see the Wh consumed.
The zero 2 might draw 2 times more, but for much shorter (less than half the time) , thus using less overall energy.
But i think that the idle power draw will still keep a place for the original zero W on battery.
Well done Jeff ! Very interesting
Wonderful! Finally a pi zero W that can handle all my dashboards. Wonderful small thing for running my smarthome display + dashboards
Great Content, I hope your channel is taken to another level so you can do bigger and better, tests with PI's
You mentioned the Kubernetes cluster; I just made a docker swarm cluster using 3 RPi Zero 2 W. The catch is that you will need to use ARMv7 as your base image for your containers. But it's incredible to see such a tiny PCB perform much. 😁
Preordered a Zero 2 W for ~18$ in a local store in Europe.
Can't wait to put my hands on it.
Jeff does great impression of Chris 👏
Yes, at 11:43 🤣
@@richard_developer_agriculture Yeah, i said to Chris sometime on TH-cam that when the intro starts i always think the news journal start with very important news. :) I got a like.
On the original Pi Zero W it made a difference to disable USB power. You might try that too, if you're looking to present minimum power requirements.
I used a Pi Zero W in a "Linux on Solar power" project. It turned everything off and only woke up every minute to record solar power stats from the Solar Charge Controller.
Nice idea; haven't tried that but I will.
Jeff a nice video again. Definitely a big upgrade for the original Pi Zero. I wonder if you run a camera with an RTSP stream thru the raspivid command? Would it use only one Core and would it benefit from the better performance? Less video lag would be a great benefit.
This is perfect for my needs! A while back, PRUSA of the MK3S fame released a guide to attach a Pi Zero directly to their Einsy RAMBo board in a seamless case solution. Just one problem: the Zero could run OctoPi okay by default, but attaching a camera caused things to explode in a hurry. Even with the same amount of memory, the 02 should have more than enough processing power to run OctoPi with a camera streaming at the same time. I'm sold!
Yeah, this little guy is ideal for use with 3D printers, though if you stream the camera feed, consider backing it off the 480p
@@JeffGeerling Oh no, the stream will be 480p, but ideally I want to attach a USB webcam for Octolapse streaming as well. My machine has the MMU2S, which means I want a camera on the selector. Maybe I should jerryrig a servo HAT in there to slide the camera up and down in it's enclosure?
That's nice! I can't wait to get mine! The old one is lovely, but this one si simply better!
Looks awesome! Super excited to order one, boot it up once and never touch it again!
Wooo, new videos from Jeff, Chris at Explaining Computers and Liz from Blitz City DIY! It's a happy Thursday!
Great video. Unfortunately the increased heat kills it for me. I love my Zero W and that I don’t need a fan, heatsink or heatsink case for it.
I use my zero as a wireless AirPrint server, Flic bluetooth server and HDMI-CEC bridge. It gets its power from my ordinary powered USB-hub. No additional power supply needed.
It's official, Jeff is the MKBHD of Raspberry Pi, getting all the new stuff before the release
Just need a fancy embargo box!
Oooo! Very pleased the zero got an update!
Disappointed by the fact it only has 512mb RAM although ultimately it’s going to depend on the use.
Maybe they'll release 1gb (or even 2gb) versions a few weeks later so the early adopters get to buy one of each like they did with the 8gb. if i'm not mistaken there was articles stating 8gb would not be released initially
@@beartastic-ftw Did you see bigger than 512MB piggyback RAM module...?
@@beartastic-ftw There's no space for a 1GB RAM die on top of the CPU die
This is such an excellent video. I nearly didn't watch it due to the click bait title. Subscribed so I can see your Null2 build!
love the outtakes
I'm excited because the Pi Port in my Prusa MK3S will hopefully now be useful! Just pre-ordered one to test it out!
OctoPrint tested it on a Prusa and said it was working great; much better than the Zero W!
This was HILLARIOUS! Right after the "Outtro and outtakes," with the reference to Christopher's channel, the video stream went RIGHT INTO his Explaining Computers "Raspberry Pi Zero 2 W: We have a new Pi!" video. I literally laughed out loud. Enjoyed BOTH of your videos on this. Shame they didn't put 2GB on the new chip. Really cripples it when you want to do some processing on-chip before sending over the network.
Haha nice, I guess TH-cam agrees that our videos pair well :D
I’ll totally buy some to replace the zeros I already have.
One per customer:(
It would be awesome if you got some Radx boards to try out. I've got their Rock Pi 4 which has 4 lanes of PCIe Gen 2 (in M.2 form factor), USB 3.0 on die, built in eMMC, and AES acceleration.
Thanks jeff for the infromation
Thanks for bringing up the Null 0! I have the complete kit and have now been wondering if I should get a Pi 02 for it. Decided. I will!
Check out my video coming Wednesday ;)
You are making us to want at least 1 of these. Cool channel. Thanks, Bro! Interesting Strato behind you (",)
Thanks for show us the Zero2! I have original Zero W running my DNS server and went with it over a full Pi because I liked the smaller power usage with it running non-stop, so that was nice to see you captured the 2's power as well. I am curious thou how did you get the speeds for a wired connection, should I assume you connected an USB to Ethernet adapter to it or is there another option to add a wired connection to the Zero I have overlooked? 👀
Would love to see a video on how you got this x-ray!!! With the holidays around the corner I was thinking of acquiring a Roku 4K but was hoping there might be an SBC you could recommend which would play videos as well as a Roku 4K using a Linux distro.
What instrument did you use for the X-Ray? I’m guessing the local TSA didn’t let you use theirs. In all seriousness though I too would really be interested to see a video about how you did this and who you worked with.
Good impression of Chirs !
just orderd 2 from pihut will be here tomorrow .. 4 cores will deffo help ..:) cheers for jeff and chris and eta for the pi bomb i got this morning lol
Looks great, I kept getting put off building a basic IP security camera with original Pi Zero W due to lack of processing power, looks like this might do the job.
I got lucky and ordered mine from Pimoroni, it was in stock as of late afternoon 29th October. I'm going to use it as a faster but still cheap Pi-Star platform for my digital ham radio modes. It will be nice to have enough power to run DMR, DStar and System Fusion all at once without the Pi bogging down.
Holy crap, I thought I'd never see v2 of this
The trick is to turn off the v1 specs in the kernel settings under system settings and then you fart
Heh, I just barely got my first Pi 0 W and was thinking today that it was getting decently old, then bam, new version! Hope I can get my hands one one, seems great.
The new one *always* comes out right after you buy the now-old one.
Same here, I just bought 1 one month ago
@@YoshioVids I got mine less than a week ago haha
I really hope you will never stop being Jeff Geerling. :P
I'm so glad I bought a handful of PiW's last month...
got mine today so now i have every version of the zero
Hey, looks like it might be time to add a redundant pi-hole finally. Been using the OG pi zero w for my primary pi-hole for years and I love it.
Excellent use case for it.
I love the Pi Zero W, and been waiting for a potential Zero 2 W, I'm so happy, I must have one, not sure what I'm gonna do with it yet though.
kvm, wireguard, WIFI remote 'down the garden shed' clients gui -nomachine- terminal, OPEN MPTCP ROUTER, Openwrt , 'batman mesh' to red shirt's remote sister for .local ip lan 'phones' ...... any combination of above for fun...
Finally! Yes it would have been much better with 1Gb of RAM but I'm not going to complain.
Ever since faster Pi's became a thing sufficient power in the smaller form factor versions to actually be useful as something more than a glorified microcontroller has been a glaring omission.
Now if the Raspberry Pi foundation could finally, finally, come out with an "A" model that contains the Pi 4 SoC I'd be delighted!
No, no, no, the Compute Module is not a reasonable alternate for those wanting a Zero with a bit of 'grunt' or an "A" of equivalent power to the Pi 4. Once you have factored in the inevitable IO board it's too expensive for most people's projects and when coupled to any IO board that has a useful range of ports you end up with something larger than a Pi "B" anyway.
PS
If there really is to be no "A4" I would really appreciate the option to buy "B4s" with the connectors and GPIO supplied separately. Being able to ignore what you don't need or mount connectors remotely would be a real boon to those of us who are forever disordering stuff from their new Pi's.
I love the logo on the BGA :)
We have 08:00 in Germany and again a super video from you. Thank you very much. Really brilliant information. Greetings PS: What makes the blade project?
Looking forward to the ETAPrime style intro in the next one
Could you test some heatsinks so we know which heatsink to get to run this Pi at 1.2?
And would a cluster of these be better for your use case than your current cluster?
great video!! did you know if the wifi chip is still able to do monitor mode?
I have been using a Pi Zero with my alarm system to send SMS Stuart updates with an SMS hat. Works great.
Brazilian olDman very great video , very great job... congratulations...
I am dead at the explaining computers at the end. 🤣
Can’t wait to see the Pi 5
I've just bough two (one in two shops). I'm eager to receive them.
Very good. Thank you
I signed up for the MagPi magazine just to be able to get my hands on one of these. It arrived via the mail on Friday. I loaded up RetroPie on it, and it would not run. It kept crashing, would not connect to wifi, or it would just not boot. Then I saw that the weekly builds support the zero 2, not the stable release. So I used that... And, man, this thing can emulate those old games much better than the original. Even some more intensive play station games run with a little overclocking (1300), but it does get hot.
That was a neat Easter Egg there with the raspberry logo.
Yeah, I did another video on building a handheld gaming device where I mentioned the RetroPie issue. I hope they get out a new release soon!
3:55 wow what an amazing easter egg
I already ordered one
I believe that after problems in the beginning with Far Eastern built products, they transfered the pic and place manufacturer to Sony at Bridgend in South Wales UK.
Using the Zero 2W with the HQ Cam for project likes a microscope would be a good upgrade.
Really excited about these new units, I can't wait to give one a shot, but I am a little worried about how available they're going to be, CM4s and the normal Zero W are both still very hard to find due to limited supplies, and if anything adding a new unit to their product catalog will only hurt that further unless they're also seriously upgrading their manufacturing capacity.
superb! does it work in the gpi case?
Great video 👍. If I used this to replace the Zero in the web cam project, would it handle 1080p?
I now feel the strong urge to make a gaming handheld with this
Love the nods to LTT and EC!
I'm glad they gave the new zero 4 cores, 512mb of ram seems like limitation, I'm wondering if swap could help, but might be too slow
Hopefully next gen pis have in house designed SOCs
35 bucks for a PI would be a dream here. They start at 70 and even the smallest RPi4 is 80 bucks. Using it for my 3D printer (Ender 3 V2), it should speed up the printing process and precision to another level. The logo under the chip is fun though :) I snatched on at release date though, maybe I just buy 2 more?
1) to get around using swap, enable ZRAM. That should help a smidge. 2) Zero 2 W lacks an "AV" Composite pinout which can be a deal breaker for some retro projects. Cheers.
If you watch the Explaining Computers video on this Zero 2 W, he shows you that there is, in fact, a way to solder composite video access from the bottom of the board.
I'm with ya on usb-c. Kinda annoying having to solder my own USB with C connector onto my PI Zeroes. I get that it's probably cheaper and you don't get high-speed USB but it saves so many headaches as I only have usb-c hubs that provide power, data and network than I've ever owned that are micro compatible.
Yeah even ignoring all the high-speed and alternate modes that the Zero can't do, just the physical USB type C connector would be great to cut down on the number of different cables to keep around.
I needed a micro-usb cable with data recently, I think I found my only surviving one after finding all of my other non data-capable ones first. Not having to worry about that anymore (as much) would be fantastic.
Yea personally I would have preferred USB-C to micro-USB, though as said, I can see why, for compatibility with older cases/spaces the original would fit in.
One of my ongoing interests is seeing if I can do everyday user stuff on the smallest computer possible. I’m going to try this. Can I watch a video? Write my stuff (word processing only)?
Connectivity, etc? I think I’ll try it with this version now. We’ll see. It’s just one of my weird hobbies. Will try a zero2 null build - when they’re available.
I will get one!
when.. it's in stock again (at the place I'll buy)..
