1.Description:
  1>.The motor driver module itself is equipped with a built-in L9110S chip that can drive 4 DC motors or 2 4-wire 2-phase stepper motors simultaneously.
  2>.The module operates with a power supply voltage range of 2.5V to 12V.
  3>.It is suitable for motors within the voltage range of 2.5V to 12V and with a maximum operating current of 0.8A. This voltage and current range covers most of the smart car motors available in the market.
  4>.The module has the capability to drive either 4 DC motors or 2 4-wire 2-phase stepper motors at the same time.

3.PCB wiring terminal description:
  1>.MOTORA: Connects to 2 pins of a DC motor without any specific direction.
  2>.MOTORB: Connects to 2 pins of a DC motor without any specific direction.
  3>.MOTORC: Connects to 2 pins of a DC motor without any specific direction.
  4>.MOTORD: Connects to 2 pins of a DC motor without any specific direction.

4>.Module Instructions:
  1>.Turn on the VCC and the GND module power indicator light is on
  2>.When A1 is set to a high logic level and A2 is set to a low logic level, the MOTORA motor rotates in the forward direction.

  3>.When A1 is set to a low logic level and A2 is set to a high logic level, the MOTORA motor rotates in the reverse direction.
  4>.When B1 is set to a high logic level and B2 is set to a low logic level, the MOTORB motor rotates in the forward direction.

  5>.When B1 is set to a low logic level and B2 is set to a high logic level, the MOTORB motor rotates in the reverse direction.
  6>.When C1 is set to a high logic level and C2 is set to a low logic level, the MOTORC motor rotates in the forward direction.

  7>.When C1 is set to a low logic level and C2 is set to a high logic level, the MOTORC motor rotates in the reverse direction.
  8>.When D1 is set to a high logic level and D2 is set to a low logic level, the MOTORD motor rotates in the forward direction.

  9>.When D1 is set to a low logic level and D2 is set to a high logic level, the MOTORD motor rotates in the reverse direction.

5>.Package:
     1pcs L9110S 4 Channel DC Motor Drive Module
