 1  L9110S-chip motor drive

6P black bent pin description:

1 VCC external voltage 2.5V-12V

2 GND External GND

3 AIA external microcontroller IO port

4 AIB external microcontroller IO port

5 BIA external microcontroller IO port

6 BIB external microcontroller IO port

4P green terminal:

   1 OA1 OB1 contact DC 2-pin, non-directional
