Board schematics

Postby drmacro » Tue Dec 25, 2018 8:36 pm

Hi,
Not sure this is the right forum for this question, but, I tried to post in the documentation forum and it wouldn't let me... :(

I have this board:
https://www.banggood.com/Wemos-TTGO-ESP ... 81331.html

I can't seem to find a schematic that I believe is actually of this board.

The silk screen on the board shows ESP32V1.0.0

In particular, I'd like to know what the battery power/charging circuit actually is so I don't let any magic smoke out... ;)

Thanks for any pointers.

I think that board is the same as the Adafruit Huzzah32. I published some notes about the Huzzah32 board at https://github.com/pantaluna/esp32-mjd- ... ev%20board

If you only want to know the polarity of the JSTPH2 battery connector then you can use a multimeter. When you buy JSTPH2 connector+wire from Aliexpress then you typically have to swap the wires. The Adafruit ones have the correct polarity.

Thanks for the info!

The Adafruit links work fine. Couldn't get the wemos links to load.

So, is this board a clone of the feather, or vice-versa?

The Feather is the original.
