esp32 thing, get battery status?

Post by tedder » Sat Dec 16, 2017 9:44 pm

The 'thing has a nice little lipo connector and 73831 chip. I see the chip has a 'stat' pin, and that's connected to an LED, and.. it doesn't appear to be connected to a pin. I can't find anything in the Thing documentation about it, but I thought it might be possible.

Ladyada puts it on A13. I can probably do a divider outside of the chip but I wouldn't be surprised if Sparkfun implemented it.

Looking at the schematics of the board, this is not implemented.( ... ematic.pdf) Maybe they did not want to "sacrifice" a pin by default as implementing a voltage divider is extremely easy if you want that (as they did on the Ladyada)
