For brushed DC motors. Can drive most existing tillerpilots and mechanical wheel pilots.
| Voltage | 11.2-30v |
| Controller Current | 15mA to 22mA |
| Motor Current | up to 20A |
5 large wires attach to an external terminal block:
| 1 | Clutch - | Yellow |
| 2 | VCC, Clutch + | Red |
| 3 | GND | Black |
| 4 | Motor A | Blue or Green |
| 5 | Motor B | Blue or Green |
The power should be applied to the red and black wires. The motor is powered from the two blue or green wires. An optional clutch to engage the drive can be connected to the yellow and red wires.
| 1 | 2 | 3 | purpose | raspberry pin |
| Red | Brown | Black | +3.3v | 1 |
| Green | White | Brown | tx | 8 |
| Blue | Blue | Green | rx | 10 |
| Black | Black | Blue | 0v, GND | 6, 9 |
Note: wires colors will be one of 3 possibilities depending on the controller.
3 wires can be used for optional end stops. End stops prevent stalling the motor and stress to the drive.
Black - GND, 0v.
Yellow/Red - port/starboard stop switches, shorted to ground prevents further movement in that direction.
3 wires are used for optional rudder feedback.
| 1 | 2 | purpose |
| Red | Brown | +5v |
| Yellow | Blue | voltage for angle |
| Black | Yellow | GND |
Note: wire colors will be one of 2 possibilities.
A potentiometer with only 2 wires can connect to yellow and black pins. A resistor should be added from red to yellow of 1k ohms.
A hall effect sensor with analog output can be connected to these 3 wires.
Optional 10k NTC (2 wires) for temperature of the electric motor.
This is generally not needed because most motors will not overheat unless stalled for prolonged periods. It can be used to prevent the motor or drive system from overheating and burning out.
