Review on π Enhanced Songhe Mega2560 + WiFi R3: Mega NodeMCU with USB-TTL CH340G, ATmega2560, ESP8266 32Mb Memory β Arduino & WeMos ESP8266 Compatible by Jay Hill
Switch settings for using an external power supply and no USB cable
A useful tidbit I learned through trial and error: If you want to use this board with an external power supply without connecting it to the USB port, you must set DIP switches 1 and 2 to ON and DIP switches 3 to 7 to OFF.
- Top marks for support and durability from testers
