The only stumbling points are:ġ.) The NODEMCU “Arduino friendly” pin names (D0 thru D8, plus RX and TX) don’t correspond with the actual ESP8266 GPIO pin numbers, so you have to make special arrangements to map the “D1”, “D2”, etc names to the actual GPIO pin numbers. It uses a somewhat different tool chain to compile the Arduino C code into binary files executable by the ESP8266, but the Arduino IDE and most libraries are the same. Both of these boards also use a WCH CH340G USB-to-UART bridge chip.Īs an Arduino-phil I use the ESP8266 Core from GitHub to adapt the Arduino IDE to the ESP8266. I suspect the same will be true for the Amica v0.9 (yellow or blue PCB) NodeMCUs (both considered out-dated) and the DoIt/SmartArduino brand NodeMCU V2. I have also found that these drivers work fine when connecting the LoLin NodeMCU V3 to my Windows 7 PC (I had to do nothing, since I had already loaded the drivers for my cheap Chinese Arduino Nano clones).
