5. INSTALLATION (HARDWARE)
5.1 Connecting Battery and Motor
In a typical application, the motor power supply (battery) should be soldered to
connector provided. The control pin come with connector and is ready for user to interface
with wire.
12V should be supplied (12V) to this driver for logic operation. CW and CCW control
the activation and direction of the motor, while the PWM pin turns the motor on or off for
speed control. CW and CCW will activate the on board relay. Thus providing 5V using a
switch or relay to these 2 pin can turn on the relays further drive the motor. As for PWM pin,
user may provide a constant 5V to it if no speed control is required.
5.2 Connecting to Microcontroller

5.3 Connecting to switches (without microcontroller)
Typical Application Circuit using switches (no speed control)
5.4 Reverse-battery
The motor driver boards do not have any protection against reverse-battery. If user
connects the battery or power source wrongly it will damage the on board clamping diode
and further burn the driver. Thus please be careful during making connection.
