Not a super technical topic, but I have a few EPS-12E test boards that I ordered (these - http://www.aliexpress.com/item/ESP8266-ESP-12E-serial-WIFI-Industrial-stable-version-A-full-test-board-Full-IO-leads/32370570377.html) that I ended up not using for the project I originally intended, so for "fun" I'm hooking them up to various lights/etc in my house and sticking them in old cigar boxes.
Anyway, I haven't been able to find a schematic for the board anywhere, but there are a number of LEDs that seem to be lit when I'm using this board, even when CH_PD is pulled to ground. I'm GUESSING they are coming from the power/voltage regulation circuit, but I'm not 100% sure. The thing is, I'd like to run this thing off of batteries, in an opaque enclosure, so LEDs don't do a whole lot for me .
Any tips on how to reduce/disable/remove the power draw from these LEDs on this board? I'm guessing there are a number of people on the forums who have used this board quite a bit in the past so I'm hoping somebody might have some great ideas
Thank you as always!
