About this board
The ESPDuino (also written as ESPDuino ESP-13 or Doit ESPDuino) is a Wi-Fi development board built around the ESP8266 on the ESP-13 module, laid out in the classic Arduino Uno R3 form factor. Developed by Doit, it works with standard Arduino Uno shields and breaks out the ESP8266 GPIO pins, making it easy to add 802.11 b/g/n Wi-Fi to Uno-style projects and IoT builds. In this guide, you'll find the ESPDuino pinout, datasheet, technical specs, and setup instructions.
