shop/ circuitrocks/ wifi r3 atmega328p+esp8266(32mb memory)board

The UNO+WiFi R3 ATmega328P + ESP8266 Board combines an Arduino-compatible Uno R3 layout with built-in WiFi support. It uses the ATmega328P for standard Arduino projects and an ESP8266 module for wireless connection, making it a practical board for IoT, automation, and remote monitoring projects.

It also includes a CH340G USB-to-serial converter for easy programming through USB. With its Uno R3 pinout, this board works well with many common Arduino shields and modules.

Great for students, hobbyists, and makers who want one board for both basic microcontroller projects and WiFi-based builds.

Features:

  • ATmega328P main controller
  • ESP8266 WiFi MCU with 32Mb memory
  • CH340G USB-to-serial converter
  • Uno R3 pinout
  • Recommended supply voltage: 6–9V
  • Compatible with Arduino Uno-style projects
  • Useful for IoT, smart home, sensor, and wireless control projects
