![]() The new version NodeMCUv1.0 comes with the CP2102 serial chip,you can download and install the driver here. In order to upload code to the ESP8266 and use the serial console, connect any data-capable micro USB cable to ESP8266 IOT Board and the other side to your computer’s USB port. Use the USB cable to connect your NodeMCU to the computer,you will see the blue onboard LED flicker when powered up, but they will not stay lit. The NodeMCU programming can be as easy as in Arduino,the main difference is the distribution of pins in the nodemcu board.Following below operations and enjoy your first NodeMCU & IDE travel! 1.Connect your NodeMCU to the Computer The Osoyoo NodeMCU comes pre-programmed with Lua interpretter, but you don’t have to use it! Instead, you can use the Arduino IDE which may be a great starting point for Arduino lovers to familiarize themselves with the technologies surrounding the IoT.Note that when you use the NodeMCU board with the Arduino IDE ,it will write directly to the firmware, erasing the NodeMCU firmware.So if you want to back to Lua SDK,use the “flasher” to re-install the firmware.
