Description
WIFI ESP8266 NodeMCU V3 Module
Wi-Fi module based on the high-performance ESP8266 chip (compatible with: Arduino, ESP32, Raspberry Pi). The chip includes 10 GPIO pins, a 1-Wire bus, I2C, an analog-to-digital converter, and a built-in PCB antenna. The board features a USB-UART CH340 or FT232 converter for straightforward programming with Arduino IDE or PlatformIO. The module can also be programmed in MicroPython, and firmware can be updated over Wi-Fi without having to connect to a computer every time.
