Introduction to AM-CD2L

- Small DC motor drive board (Max current limit 100mA per Motor)
- Drive two small DC motors
- Control signal and drive power supply are received through the 10Pin Cable.
- Possible to drive in both forward and reverse direction

Small DC motor drive board, AM-CD2L

Connecting the Connectors

- Pin descriptions of 2x5 box header

1st	3rd	5th	7th	9th
Left motor B phase	Right motor B phase			VCC(5V)
2nd	4th	6th	8th	10th
Left motor A phase	Right motor A phase			GND

Pin numbers of DC motor connector J952, J953

Motor connector wiring method

1	DC motor A phase
2	DC motor B phase

Using AM-CD2L (DC motor drive module)

Connect the phase A and phase B of motor control signal to the microcontroller's port input.

	CCW	CW	Stop	Stop
A phase	1	0	1	0
B phase	0	1	1	0

Input signals for motor control is above. If 1 is applied to Phase 1 and 0 to Phase B then motor rotates as CCW. In contrast, if 0 is applied to Phase A and 1 to Phase B, the motor rotates as CW. To stop the motor, the same input should be applied on the phase A and B, and if the all the value is 1, then it will break very strongly
