Description
ESP8266 NodeMCU V2 CP2102 WiFi Microcontroller for Arduino
ESP8266 NodeMCU V2 CP2102 WiFi microcontroller is a versatile device recommended for IoT projects and hobby electronics.
With 16 GPIO pins, 1-Wire bus, I2C, an analog-to-digital converter, and a built-in PCB antenna, it offers rich capabilities for a wide range of applications.
The board integrates a USB-UART CP2102 converter, which enables easy programming in the Arduino IDE.
Users can also program the module in MicroPython or Lua, offering even more flexibility in choosing a programming language.
One of the microcontroller’s key features is the ability to program it over WiFi, eliminating the need for a constant connection to a computer. This greatly simplifies developing and testing applications in real-world conditions.
The V2 version of the ESP8266 NodeMCU microcontroller stands out for its board size compared to the V3 model. Its width allows convenient placement on 400 or 830 tie-point breadboards, leaving one row of holes free on each side.
