The L9110 Motor Driver Module, using 2pcs of L9110S chips, it can drive for two DC motors or one 4-wire 2 phase stepper motor
L9110 is designed to control and drive motor of the two-channel push-pull power amplifier application specific integrated circuit devices, which will be separated in a single IC, and so reduce the cost of peripheral devices, to increase machine reliability. The chip has two TTL / CMOS compatible input level, and good anti-interference; two outputs for direct drive motor to the positive and negative campaigns, it has a larger current drive capability, each channel can be 750 ~ 800mA continuous current, peak current capacity of up to 1.5 ~ 2.0A; At the same time, it has a low output saturation voltage drop; built-in clamp diode to reverse the release of the impact of inductive load current, to make it in the drive relays, DC machine, stepper motor or switch power control the use of safe and reliable.
A set of male header pins is used to connect this module to your robot's microcontroller brain. The motors are attached via two sets of screw terminals.
A PWM Pulse Width Modulation signal is used to control the speed of a motor and a digital output is used to change its direction. This module can also be used to drive a single four line two phase stepper motor. Four holes make this board easy to mount onto your robot or other project.
L9110 has been widely used in toy car motor driver, stepper motor drive and switching power circuits, etc..
