Universal Combat Robot Controller      

by Tomasz Rejmer

Universal combat robot controller based on Atmega328AU, which allows radio control of two DC motors and 6 IO ports. The system is recognized by the computer as Arduino Nano, making it convenient to use and compatible with the Arduino IDE environment.

The controller has the following hardware functions:

• Built-in XT30 power connector,
• Switch connector,
• Built-in status power LEDs,
• 5V and 3.3V voltage converters,
• 5V power strip,
• Reset button,
• Two built-in H bridges,
• Pinout for the nrf24l01 module,
• 6 IO ports (2x PWM, 4x ADC, 1xI2C),
• Communication via mini USB B,
• Communication via SPI,
• Communication via I2C,

Microcontroller IO port list:

• PD2 (Arduino port 2) – M1A,
• PD3 (Arduino port 3) – M1B,
• PD4 (Arduino port 4) – M2A,
• PD7 (Arduino port 7) – M2B,
• PB1 (Arduino port 9) – CE,
• PB2 (Arduino port 10) – CSN,
• PD5 (Arduino port 5) – PIN1,
• PD6 (Arduino port 6) – PIN2,
• PC2 (Arduino port A2) – PIN3,
• PC3 (Arduino port A3) – PIN4,
• PC4 (Arduino port A4) – PIN5, SDA,
• PC5 (Arduino port A5) – PIN6, SCL,
