  • The ESP32 has become a mainstream Maker platform. Therefore, we have many different boards to choose from. Which one fits your project? Let’s get an overview and test the boards. And of course, we will add the information to our comparison table from the last videos.
    Contenders are boards from Lilygo (TTGO), Wemos (LOLIN), Sparkfun, Keyestudio, and MH-ET LIVE.

    Andreas, thanks for mentioning shipping costs and woes. I have been fighting these lately, as well as items getting lost, cancelled or significantly delayed. I find ordering through distributors and through bigger eBay sellers and Amazon and those with local stock to be faster, more reliable and affordable. Digikey was a favorite distributor when I was a design engineer for similar reasons. As with much of the pandemic I fear these choices may result in smaller businesses being pushed out, but what can you do? +1 for a future video on the topic and the supply chain in general.

    @Andreas. Thanks for your table. I have one question (sorry, I am totally new to this): Is the 3.3V Pin on the boards only input or also output (if powered over usb or lipo), and if yes, how much current does it supply? I am especially interested in the TTGO T7 V1.5. Thanks for an answer.

  • @marcvisser5140
    @marcvisser5140 3 ปีที่แล้ว +1

    Great video! Quick note about the TTGO T7 versions and the Live D1 mini: The inner pin headers have the same form factor and pin layout as the Wemos D1 mini. This enables a lot of readily available shields to be used! They can often be a drop in replacement by just changing some pin definitions.
    I always use the TTGO T7 V1.3 as it does not have PSRAM, and thus has pins 16 and 17 also available!

I that time the 1 1/2 year i have tested Europe produced boards too because of warranty issues when needed. But still ím on the D32 Pro. It works very well and i use all connectors.

    I especially appreciate the info on power usage in deep sleep - - accurate data is hard to find. I'm delighted to know that Lilygo improved that issue in their new v1. 5 of the T7 TTGO (after desoldering the LED). However, the link you provide currently offers the v1. 3 board instead, probably because the 3rd-party vendor changed the product at that link. I almost ordered it before I noticed. Perhaps you should link directly to the LilyGo store on Aliexpress instead?

    @Andreas Spiess excellent videos, they are so helpful. You asked if anyone knows of any ESPs that doesn't need the button pressed to upload code, I have not read the 586 comments below so if this has already been mentioned sorry. The "DevKitc v4" and "ESP32-S2", when uploading code from fast desktop almost never, but with slower laptop most times button needs holding down. So pooling resources with you and others my experience with these modules they have slightly better antennas than the "DOIT" boards, probably because the antennas have more space and over hang the main motherboard. Unfortunately the DevKitc v4 does use the AMS1117 regulator for the 3.3v however the board maker, Espressif, say it is fine to power the 3.3v pin directly with your own power supply, therefore one could assume deep sleep power usage is low but I have not proven if the AMS1117 leaks power on it's output pin, the power LED would also need removing. I power my boards via PoE splitters so I prefer a mix of deep_sleep and light_sleep.

    • @AndreasSpiess
      @AndreasSpiess  3 ปีที่แล้ว

    Hi Andreas,
    i really wonder why the power consumption is so different across the boards...
    If the battery input is passing a voltage regulator for the boards with the higer consumption, and the "winners" are cheating by just passing the 3.7v to the Processor directly, i would consider that as a bit unfair (maybe the other boards would be able to perform the same if you connect the battery to the 3.3v Pin?!?)
    For my plans i learned (from other Videos / Articles) that the best options for long running battery powered projects is two Lithium AA Cell which stay at 1.5V for a pretty long time... Here the Li-Ion Battery seems to be a real option, at least if the two winner boards to regulate the battery in.
    Did you investigate why these extreme differences exist?
    By the way ... thanks for the video - reaaally useful information on your channel!!

    • @AndreasSpiess

    Your Keyestudio board looks exactly like my DOIT boards. I found that I often have to press the EN button to get a sketch to load, but a capacitor from the EN pin to ground sorts out most of them. Some boards are said to need 10uF, I have 0.33uF on mine and it's fine, yet I also have one board that never gives a problem at all. It seems to be worse on my new MSI motherboard than on my previous Gigabyte board (vintage 2009!).

      The TP4056 charges the battery, so it has to be connected to the battery. If you use a module with protection, you have to connect it according to its data sheet ( www.aliexpress.com/item/32930640893.html )

    have you thought about designing some of the boards, ordering them and soldering yourself? most of these boards have just basic components like ldo regulator, some leds, usb-to-serial chip and a battery controller. The shield is easy to solder and bypasses hard challenges in wiring it in correctly. If you need more than 10 of these devboards I would definitely go with this. The most expensive part of course is the esp32 shield and you can get it as cheap as 2.2$ per piece on lcsc and the pcbs are almost free on jlcpcb. As to make it easier to solder, just using through hole and dip chips should do the trick.
