Product Usage Instructions:

Enable: Power on the device.

Control Lines:

• Pwml1: Controls forward movement.
• Pwml2: Controls reverse movement.
• GND: Ground connection for power supply.

Output Connections:

• VIN+: Positive power supply input (Active 10V-36V)
• GND: Negative power supply input
• M+: Connect to positive motor wire
• M-: Connect to negative motor wire

Control Methods:

Level Control Method:

• En = 0, Pwml1 = 0, Pwml2 = 1: Motor rotates forward
• En = 0, Pwml1 = 1, Pwml2 = 0: Motor reverses
• En = 0, Pwml1 = 1, Pwml2 = 1: Motor brakes
• En = 1, Pwml1 = 1, Pwml2 = 1: Motor is free

PWM Control Method:

• En = 0, Pwml1 = PWM signal (adjustable), Pwml2 = 1: Motor rotates forward, speed adjustable
• En = 0, Pwml1 = 1, Pwml2 = PWM signal (adjustable): Motor reverses, speed adjustable
• En = 0, Pwml1 = 1, Pwml2 = 1: Motor brakes
• En = 1, Pwml1 = 1, Pwml2 = 1: Motor is free

Package Includes:

• 1 x Module Board
