This module can drive one stepper motor. It uses the hugely popular Allegro A4988 IC. The stepper motor can be controlled through just 2 pins - one for direction and the other for speed and step control. This makes it easy to control the speed and position of the motor from a microcontroller, Arduino, Raspberry Pi, etc. It offers numerous features like features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It can drive stepper motors with an input voltage of 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
