NodeMCU V2 WiFi module - wireless module based on ESP8266-12E - tested
Popular PCB with built-in WiFi ( ESP8266-12E ). It gives great possibilities of use in projects where wireless connectivity is required.
The module is programmed via the Micro USB connector. The board is compatible with Arduino, MicroPython and NodeMCU.
We have 10 GPIO ports at our disposal. Each of them supports PWM, I2C, SPI and 1-Wire. There is a 3.3V voltage regulator on the board, so it can be powered from the USB port.
