What nodemcu firmware do you flash on your esp-12's. When I just leave all the settings on default like I do when I flash my esp-01 it flashes and says it succesfull ( shows chip data MAC etc.) but does not work afterwards. I pull GPIO 15&0 LOW but it won't flash correctly. Does it need more power than the ESP-01 or am I doing something wrong?

This one, at the moment:

I pull GPIO 15&0 LOW

...and CH_PD high, right?

Good work so far tracing out the pins - we do the work the vendors should do for us, and do it better than they do too

i found also this blog post with photo and trace about the breakout board; the image is:



of course, the jumper means "ready for firmware upgrade" when closed and "normal run" when open.

now going to test the ADC with the light sensor..
