Boffintronics RoboBoffin Mini Controller

This is the custom designed Boffintronics RoboBoffin Mini control board used in the Cardboard Sumo Bot Addikit. It is based on the ESP8266 ESP-12 module and is compatible with the Arduino IDE and with NodeMCU.

The board includes an on-board USB Micro connector and USB to serial (UART) converter, making it easy to power and program the board by simply connecting it to your computer with a USB Micro cable.

Included are 12 headers set up for driving servos (5V, signal, and ground). Additional signals provided via P2 and P3.

Each board will come with the Cardboard Sumo Bot Driving software already installed. You can easily reprogram with your own code.
