Dual L9110 driver chip for two DC or one 4 wires stepped motor, operated from 2.5V

up to 12V, is able to drive motor up to 0.8A max.. It is small in size, only

measures 28 x 21mm ideal to be used in small robots.

Pin connections:

1 VCC  2.5V-12V DC

2 GND  GND.

3 IA1  MCU or PWM controller IO

4 IB1  MCU or PWM controller IO

5 IA2  MCU or PWM controller IO

6 IB2  MCU or controller PWM IO

Screw terminal block connections:

   1 OA1 OB1 DC motor 1

   2 OA2 OB2 DC motor 2

Operation:

IA1 High，IB1 Low，【OA1 OB1】motor clockwise rotation.
