Is it possible to get 3.3v out of the mcore board to power an ESP8266 chip? This post suggests it’s possible, but I only see pins for 5v.
I see full 5V but no 3.3v output.
You could use a voltage regulator: DC 4.75V-12V to 3.3V Voltage ???
ok thanks for the tip! that seems a bit better than other things I was thinking to make it work so I will give that a try
