L9110S 모터 드라이버

Description:

• Motor drive of double L9110S chip
• Supply voltage: 2.5-12V
• Suitable range: Working voltage between 2.5-12V, the max working current is 0.8A
• It can drive 2 direct current machines at the same time, or 1pc two-phase 4-wire stepping motor
• PCB board size(L*W): Approx. 2.8 x 2.1cm / 1.1 x 0.83 inch (ultra small volume, easy to assemble)
• It has fixed installation holes, and diameter is 3mm 

Module port specification:

• 6pcs yellow pins:
• VCC --2.5V-12V voltage
• GND --GND
• IA1-- singlechip IO port
• IB1-- singlechip IO port
• IA2-- singlechip IO port
• IB2-- singlechip IO port
• 4pcs blue ports:
