Function
Power Battery
Input
Power source for motor. It can be as low as 5V and as high
as
19V
. The driver does not have protection against wrong
polarity on power input, thus user must be careful during
providing power source to this driver. Please follow (+)
and (-) marker on the PCB for the correct polarity.
Motor
Motor Terminal
Terminal for motor connection.
12V
Operating supply
Input for driver logic operation. User should provide 12V
CW Clock

Voltage controller input pin. These two pins control the
state of the relay in normal operation according to the truth
table 4.1 (brake, clockwise and counterclockwise).
PWM
Pulse Width
Modulation
Voltage controlled input pin. This pin is isolated using
opto-isolator. It will control the onboard MOSFET to ON
and OFF further control the speed the motor.
Gnd Ground
Logic ground signal. Internally separated from Power’s
