This motor driver shield is a breakout board for two ST-Micro VNH3ASP30 full-bridge motor driver chips. Each chip incorporates a dual monolithic high-side driver and two low-side switches for full-bridge operation. The input signals INA and INB can directly interface with a microcontroller to select the motor direction and the brake condition. Pins DIAGA/ENA or DIAGB/ENB, when connected to an external pull-up resistor, enable one leg of the bridge. They also provide a feedback digital diagnostic signal. The CS pin monitors the motor current by delivering a current proportional to its value. The speed of the motor can be controlled in all possible conditions by the PWM up to 20kHz. In all cases, a low level state on the PWM pin will turn off both the LSA and LSB switches. When the PWM rises to a high level, LSA or LSB turn on again depending on the input pin state.
