Description
Controller for a robot tank + grabber arm
Provides 4x full bridge motor outputs, each rated to 1.5A continuous (10A peak).
Also provides 8x Servo outputs, with adjustable power supply rated to 3A continous, with optional second power supply to power each bank of 4 Servos independantly.
Designed to be controlled via I2C from an SBC such as a Raspberry pi or Up board. Provides two 16ch PWM drivers, U1 runs at 1-1.5kHz for PWM control of the motors, U2 runs at 50Hz for Servo output.
