Sumo Robot Controller R1.1 - controller for Sumo robots with ATmega328 microcontroller

Description

A controller dedicated to Sumo robots. It has a built-in ATmega328 microcontroller and is compatible with the Arduino IDE. It can be a great solution for beginners who would like to start playing with sumo robots, but are not yet able to fully design the control electronics themselves. The module can power two DC motors with a current consumption of up to 10 A (continuous current). The user has the ability to connect numerous sensors necessary in robot fights, including enemy sensors, edge sensors, but also the starting module. The board has buttons that allow you to easily test the operation of the drives. The module is powered with the voltage ranging from 8 to 25 V and has built-in voltage stabilizers 5 V and 3.3 V. The controller does not require soldering, and all elements are connected via screw connectors or goldpin lists. The library with the description of the configuration are available in the project's GitHub repository.
