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. Thank you.

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!

Deep sleep current while USB powered is sometimes also important. For example when building a sensor, that also measures temperature. Deep sleep power usage from the board can easily affect the measured temperature 0.5 - 1 degrees. A lot also depends on proper case design for such a sensor.

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.

Sorry for the wrong link. It should be corrected by now. I usually use the links I purchased my boards and I got a 1.5 version from that supplier. Maybe you contact him before. Or buy where they promise the 1.5 version.

@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.

Great Overview, Thank you! If I build a solar-powered project, as described in #154​ (Solar -> TP4056->Battery) should I connect the battery via an LDO (+cappacitors) to the 3.3 v pin of the board, or should I connect the battery to the battery connector if the board has one (LoLin D32 V1.0.0)? or Maybe the TP4056 to the battery connector to benefit of battery protection?
@AndreasSpiess
@AndreasSpiess 3 роки тому
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 )

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!). Try it, you never know, it might work.

Cool video. Thanks a lot for sharing this information. Maybe you could include this board from ezsbc next time it claims to consume < 10 uA in deep sleep and also it already includes a circuit to measure the bat voltage. (With a digital switch so it do not consume current when you do not measure) It is from US. I ordered 2 and it took 1 month until it arrives. But it works. I can not verify that the current consumption in deep sleep is really under 10 uA

My first and only ESP32 (so far) is the Adafruit Huzzah32. I think they have new variants becoming available (including an "S2"). If you do another ESP32 lineup, I'd love to see how some/any of their boards stack up in your comparison. A nice feature (for me) is their diverse collection of add-on boards compatible with many of their offerings, including their ESP32 boards.

@Andreas Spiess - I have tested really a lot of ESP32 boards because i do this on a daily work day. I mean use ESP32 boards for profeesional use. I use always now since a year and a half the LOLIN D32 Pro. The one with the display adapter, ssd battery and SD card adapter. VEry well working and coding for use of both cores. 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.

Just got into this ESP thing, so this will come in very handy. Wish they would make some wider breadboards and maybe a board with a zif socket. Andreas, did you have any issues with RFI with these projects? Just made a nice wled project but it puts out a lot of rf spurious it seems (my FM receiver 5 meters away is having issues receiving like it should) . I think if I need to mount this on a pcb that I will need to have to place that data-line through some ferrite core. I see loads of projects on the web with just wires everywhere producing rf which also might interfere the onboard BT and wifi.
@AndreasSpiess
@AndreasSpiess 3 роки тому
I assume the EMI comes from your switching power supply, especially if your project consumes some power.
@Luke-san
@Luke-san 3 роки тому
It's connected to a quality power supply that already has a nice ferrite bead on the output. Maybe it's the data line (connected to D4) that addresses those leds. It's actually 1 big (antenna) wire. Guess I'll try a VK200 at the output of that pin.

Would be interesting to see how much of the POE can be siphoned off for active sensors. i.e. how marginal the power converter has been dimensioned.
