Arduino Uno R3 Compatible powered by ESP8266 WiFi Microcontroller

SKU 328220

If you want to explore the world of easy Arduino with WiFi, then order this board from PMD Way. It harnesses the popular ESP8266 ESP12F WiFi-enabled microcontroller into the friendly Arduino Uno R3 board layout. 

Even if you're not interested in adding WiFi to your projects - this board runs at 84 MHz (compared to the usual 16 MHz of an Arduino Uno) - so you have much more raw processing power at your disposal. 

All the pinouts are marked next to the stacking headers for both Arduino IDE use and regular ESP8266 notation for other platforms. 


  • 11 digital input/output pins, all pins have interrupt/PWM/I2C/one-wire supported (except for D0)
  • 1 analog input (3.2V max input)
  • Micro USB connection
  • DC power jack, which accepts 9 to 24V DC.
  • Compatible with Arduino and WeMos D1
  • Compatible with NodeMCU
