Is it possible to Power a Arduino Mega 2560 and a NodeMCU V2 ESP8266 ESP-12E from a single 9V Block?
What would be the best solution?
- Can i power the ESP8266 directly via the Arduino Mega 5V output? (3.3V Output seems to weak)
- Is a Power Converter like this for the ESP8266 necessary?
- Should i use another external Power source for the ESP8266?
Thanks for any Help :)
