ESPduino is developed based on the ESP8266 ESP-13, which can be compatible with Arduino IDE, and the UNO R3 development board. By using the ESP8266 WiFi and MCU, ESPduino can work with the support of WiFi. Compared to the traditional UNO development board, users don't have to buy another WiFi development board. It is a good help for IoT projects and robot projects. The ESPduino has an ESP-13 WiFi module. The chip is also ESP8266. So, all of the ESP8266 source code and bin files can also be used on this board. Importantly, the Arduino code is also suitable for this board. The serial chip is CH340C. So, you should install the CH340 driver program before using it.

Specification:
