Motor Controllers

Arduino shield for driving up to 4 DC motors or 2 stepper motors and 2 servos. Features two TB6612 MOSFET H-bridge drivers (1.2A continuous, 3A peak per channel) and a PCA9685 16-channel PWM driver (12-bit, I2C interface) for motor speed control and servo control. Operates from 4.5–13.5 V motor supply, logic level configurable via Arduino IOREF (5V by default). Includes polarity-protected external power terminal, reset button breakout, and stacking headers for address selection (up to 32 shields stackable for 64 steppers/128 DC motors total). Ideal for robotics projects requiring multiple motors and servos.

CTRE Talon SRX Motor Controller. High-performance brushed motor controller with CAN or PWM control for FRC.

Single-axis stepper driver module advertised as TB6600-based. Rated 9–42 VDC supply, up to 4.0 A phase current, and up to 32× microstepping. Opto-isolated STEP/DIR/ENA inputs.

Dual-channel H-bridge motor driver module based on the L298N IC. Capable of driving two DC motors (or one stepper motor) with up to ~2 A per channel and motor supply voltages from ~5 V up to ~35 V (board-dependent). Includes an onboard 5 V regulator (activated via jumper) that can power the logic circuitry and, within limits, an external controller. Provides directional control and speed (PWM) control for motors, with built-in clamp diodes and a heat sink for handling power dissipation. Widely used in robotics and motor control projects.
