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.
