A very compact dual channel H-bridge motor driver module. The module incorporates two L9110S H-bridge driver IC's to allow either one stepper or two DC motors to be independently controlled. The module can accept a supply voltage between 2.5 to 12V allowing for motors within this supply range to be controlled safely from a standard microcontroller. Maximum drive current is 800mA. 0.1" pitch header pins allow for direct connection to a microcontoller such as an Arduino requiring just two digital pins per DC motor for control in both directions. Screw terminal blocks provide convenient connection to the motors(s).

Modules Description:
  • Functio: Double L9110S chip motor drive.
  • Module supply voltage: 2.5~12V.
  • Suitable motor: Drive two DC motors, or a 4-wire 2-phase stepping motor.
  • Maximum operating current: 0.8A.
  • PCB board size: 2.8cm x 2.1cm, compact size.
  • Fixed mounting hole, diameter: 3mm;

Module interface specification:
pin description:
  • VCC: external 2.5V~12V voltage;
  • GND: external GND;
  • IA1: external microcontroller IO port;
