Product Description

This module has two H-bridge motor driver chips L9110, which can drive two DC motors or one 2-phase 4-wire stepper motor.

Product Functions

Pin Description

VCC: Connect to a DC 2.5-12V power supply (depending on the motor)

GND: Connect the negative pole of the power supply

IA1: Motor 1 control terminal, control A circuit, connected to microcontroller IO port

IB1: Motor 1 control terminal, control B circuit, connected to microcontroller IO port

IA2: Motor 2 control terminal, control A circuit, connected to microcontroller IO port

IB2: Motor 2 control terminal, control B circuit, connected to microcontroller IO port

OA1: A-way output, connected to motor 1

OB1: B output, connected to motor 1

OA2: A output, connected to motor 2

OB2: B output, connected to motor 2

Step by step motor:

If you want to connect a 2-phase 4-wire motor, here is the "A" route The meanings of phases A and B in the "B" path and stepper motor are different. If connected to a stepper motor, (IA1.1B1) corresponds to one phase, and (IA2. IB2) corresponds to the other phase.

Control development board

You can choose an Arduino development board, which is relatively easy to develop and provides libraries and sample programs for driving L9110. If you don't know how to use Arduino, you can purchase our Arduino development board, which provides detailed instructions for use.
