The ESP32 C6 is a WiFi, Bluetooth, Thread and Zigbee enabled RISC-V microcontroller that was announced by Espressif all the way back in early 2021 but sample units are now making their way into general availability! In this review we focus on the ESP32 C6 DevKit-C1. This microcontroller has clearly been aimed at the IoT and smarthome markets with all this connectivity.
There is 2.4GHz WiFi 6 802.11ax with b/g/n backwards compatibility. It has Bluetooth 5 LE and is Bluetooth 5.3 certified. And we have support for the 802.15.4 specification which includes Thread 1.3 and Zigbee 3.0 support. It’s like an esp32 c3 with extra radio functionality.

The high current draw in deep sleep is due to the additional components on the pcb. Other dev.-boards has this 'issue' too.
Yes, the voltage regulator and LED probably account for most of it.
@@johnchapman1903 and the uart-usb chip
@@johnchapman1903 another youtuber, @clough42, recently did a vid replacing the mercury batteries in a piece of old lab equipment with long life lithium cells and an ultra-low power regulator that would be *perfect* for this setup. It measured in the microamps for draw on standby. Texas Instruments TPS7A2501
Finally, someone who knows that it's pronounced as "RISC Five" and not "RISC Vee". lol Good job. Nice and Very informative Video.
This helped me get my ESP32-C6-DevKitC-1 up and running, so I can learn how to work with ESP32.
Would be very good to see a practical example of using ESP32 C6 utilising the thread programming aspect in conjunction with existing thread network ie Apple HomeKit ecosystem… I expect others would be interested in this also!
Hi, just curious about the power measurement. Can you sometimes make a video about how to measure microcontrollers power? Or maybe using other tools? Thanks, appreciate your great explanation video!
Really cool way of teaching!
4:40 that is not a typo on the datasheet. The 22pin has 4mb flash and the 30pin had no flash and needs an external flash chip which is 8mb for the module
The module itself draws 5 uA in deep sleep, but the board has components such as the regulator, which draws 5 mA. If low power is needed, the board must be modified.
18:02 Spec is for the module, you measured the dev board. You can measure the module consumption by removing the jumper (and putting your ammeter between the pins)
I would be very interested in a thread/matter example! It would be amazing if there was a straight forward matter on thread or wifi example that could be used as a starting point for custom iot devices. If the deep sleep works with the wake on thread I would be ecstatic. I've been using the nRF52840, but it's community seems much smaller then the esp32 community and getting things running on it has taken weeks with a lot of pain points.
The thread/matter explanation/demo-build from Nordic is good to understand the "connectedhomeip" framework used by Espressif, Nordic and co.
Have you figured this out? A device that can wake on RF communication would great for a few iot applications.
The C/C++ Extension Pack has the C/C++ extension in it...
along with CMake, CMake Themes and C/C++ Themes.
Thanks for the demo, this installation is a bit tricky and your presentation worked for me.
Well done.
Cheers,
we need a T-PicoC3 video next. that thing is cool..
I believe the SoC only comes up to 4MB, but the module has an extra 4MB (or just 8mb with none on the SoC) of flash added.
Very nice video, THX.
Nice info, thanks :)
Looking for to the thread demo!
I just checked the schematic. The 3.3V LDO Output is connected to CP2102's Regulator Input Pin. This has also been the case with the Pico Kit D4 Board as well.
Removing CP2102 from the board and testing the sleep current can get you the right result. I did measure 5uA range in deep sleep by removing the LDO and CP2102 in the Pico Kit D4 Board.
Why did they it ??? 😳
Without the LDO and the USB to UART converter, what purpose does the board serve? lol
Good video, new subscriber
Hi, can you send a link to the code sample you upload on the boards? (Coodinator and end device) thank you
Does it work with ESPhome?
I am looking for ESP32-H2 review, that was announced to come several weeks after this, is it available?
You need to measure current on the chip not the whole module you are measuring the usb to uart and the LDO quiescent current
The purchase link is already dead.
I'm trying to figure out how to transmit via zigbee to eps32c6 via arduino ide. Maybe you could make an example?thanks!
Hi,
When will you do a video with ESP32 C6 ZigBee?
Did you find an example with zigbee on arduino ide?
Is it thread certified?
is anyone having probelm downloading idf in mac. it seems to not run at all, the setup window itself is not opening
8MB Flash, thats the N8 model,
5mA in deep sleep is a lot! way too much for battery operated projects; possibly the on-board voltage regulator has a high quiescent current
The chip itself consumes a bit too much to transmit anything, be it WiFi or Bluetooth, just like in previous iterations (C3, etc). For power-conscious applications, it's better to use a single-stack chip (only BT LE, or only WiFi, etc.), like nrf52840 instead. Too bad we don't have a generally-available, cheap (for small makers like me) and royalty-free solution for most of this stuff, especially WiFi -- and by that, I mean outside Espressif offerings.
All in all, impressive chip, but power consumption (especially on TX/RX) really needs to improve.
zigbee battery powered devices are controllable (i.e. temperature/motion sensor or so) but when you put your ESP32 to deep sleep, there is no radio. I am wondering how they are doing this to control zigbee devices while still consuming low power and yet to be controllable - do they wake up device every few seconds to check if there is any message from the controller? that is what I do for my devices while using ESPnow: go to deep sleep, wake up, measure whatever needed, send data to the controller, check if there is any command waiting for you and if yes - then do it, if no then go to sleep again - but that is my ESPnow not zigbee - I would like to know how it is done in zigbee
Scheduled Wake up in longer intervals. You poll sensors each 5 minutes or half an hour or so and then go to deep sleep, you don't need temp sensor readings every couple of seconds usually... I think that presence of advanced sleep modes is the main advantage of ESP, when compared e.g. to Raspberry Pi Zero.
-- OR --
There is a possibility to query Zigbee when in sleep, because there's still running internal microcode and the power needed to communicate is very low (in contrary to wifi or usb). It depends on code possibilities to communicate. Maybe run simple sentence of signals from sensor might be possible ? Need to investigate it...
@@vencdee in your first case the sending device needs to be modified to accommodate this. it needs to keep retrying until there is an 'ack'. so we need a TCP like guarantee system that the message has been delivered. maybe the Thread provides this guarantee?
7:57 I can't find the TWAI (CAN) pins on the pcb antenna version, but they are mentioned below.
What's the advantage over the C3?
The thread & zigbee radio is the main one!
Sadly, the esp32-c6 does not preserver its WiFi-6 connection in deep sleep, it only does so when in automatic light sleep - which uses much more power than deep sleep. So if you are going to use deep sleep you have to code to have the esp32-c6 reconnect to wifi when it wakes up
Why sadly? That's a good thing...
Otherwise the device would be power hungry even in deep sleep mode, you silly!
@@alejandroperez5368 Silly says, read up on the low-power advantage of Wi-Fi 6 TWT
Bluetooth power consumption is disappointing. Gotta stick with NRF for BT applications that run on battery.
Still better than wifi... you may poll sensors or devices and then turn off BT/BLE.
@10:50 - and 7 months later... NADA ;-(
5mA in sleep is very, very high, not practical to run off a battery.
Kind of too big and too expensive for a "micro" controller.
You guys have no sense in promoting more Chinese spyware. What a shame.
