Description Power Supply, + Power Supply, GND Motor1_+ Motor1_Motor2_+ Motor2_Motor1 PWM Motor1 control signal Motor1 control signal Motor2 PWM Motor2 control signal Motor2 control signal

Voltage Reference Input, +5V OR 3.3V

Control Method

IN1 IN2 ENA/ ENB 00 x 11 x 10 1 01 1 0 PWM 0 1 PWM

In this table
• IN1 & IN2 the control signal input to change the motor behavior
• "0" TTL_Low
• "1" TTL_High
• "x" Any TTL, and it is default TTL_Low while no PWM signal.
• "ENA/ ENB" PWM speed setting

Note:

IN1 & IN2 To protect your motor, before switching the motor steering direction, make sure firstly to BRAKE motor by setting IN1 - 0 & IN2 - 0, especially when the PWM was set as 100%, full speed. And the suggestion time to brake is >0.1S, depending on your motor. +5V When the microcontroller operation voltage is 5V/3.3V, then please connect the reference voltage 5V/ 3.3V from the microcontroller. Or you will fail to control motors.

Connection Diagram

Back view, conductive layer Facility Safety and the Personal Safety Please add a between the Power source and this shield. Installation Tips The backside of the driver, as right-hand picture shows, that its conducting layer can be very wide, so you should take some measurements to ensure it won't short-circuit, like applying 1mm layer conductive epoxy or any other similar materials.

Pluggable Connector

You may find that the connector is designed as pluggable type to adapt with Male or Female wires.
