Actuators board

The actuator board allows for investigation into DC, servo, and stepper motors.

The Actuators board includes a DC motor with both analogue and digital feedback, a servo motor and a stepper motor, plus the circuitry to drive the motors.

The DC motor is driven using a standard H-Bridge driver IC and can be driven using simple digital on/off right through to pulse width modulation (PWM) techniques. By monitoring the feedback, a closed loop control system can be made to control the speed of the motor. A second H-Bridge driver IC is used to drive the four coils of the stepper motor allowing for full step and half step operation. The stepper motor features an internal gearbox to provide a high level of torque and precise angle control. The servo motor is a standard R/C servo motor with a supplied actuator arm.

The board features a DC socket to allow the various drivers to be powered from a secondary power supply.
