The motor driver board module uses an L9110S chip to control and drive the motor. The chip has two TTL/CMOS compatible input terminals and has anti-interference characteristics: it has high current driving capability, and the two output terminals can directly drive the DC motor. Each output port can provide 750~800mA dynamic current, and its peak current can reach 1.5~2.0A, Vcc=5V; L9110 is widely used in various motor drivers, such as toy cars, stepper motors, and power switches.
