NodeMCU V2 ESP8266 ESP-12E Development Board

The NodeMCU V2 ESP8266 ESP-12E Development Board is a powerful and affordable open-source IoT platform, based on the ESP8266 WiFi module. It’s designed for rapid prototyping of smart, connected applications, and is widely used in home automation, wireless sensor networks, industrial IoT systems, and STEM education.

Built around the ESP-12E module, the board features the ESP8266EX SoC from Espressif Systems, which combines a Tensilica L106 32-bit RISC processor with integrated 802.11 b/g/n WiFi, offering speeds up to 80–160 MHz. The chip includes 64KB instruction RAM, 96KB data RAM, and 4MB flash memory, providing ample space for custom firmware and applications.

One of the most significant advantages of the NodeMCU V2 is its built-in USB-to-serial interface (CP2102), which allows easy programming and debugging through the Arduino IDE, PlatformIO, or Lua interpreter. This makes it perfect for beginners and advanced developers alike.
