The #203 Motor Driver is one of the most popular DC motor drivers for small mobile robotics around. This great motor driver provides a simple digital interface to a pair of low current DC Brush Motors. Requiring only a pair of I/O lines per motor, it is ideal for use with microcontrollers such as the HC11 MC, Basic Atomtm, Parallax Basic Stamptm, Microchip PICmicro®, Atmel AVRtm, etc.
Both motor speed and direction are controllable. Motor speed is variable by adjusting the duty cycle of the PWM input. Potential applications include robotics, home automation, or anywhere an extremely compact motor driver is needed.
