STEPPER MOTOR DRIVER MODULE A3967

This Easy Driver compatible stepper motor driver module utilities the Allegro A3967SLB micro stepping driver to proved a simple and compact means of driving bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors from a micro controller. By default the module will accept a 5V TTL step and direction signal from the micro-controller to step the motor in either full, half, quarter, and eighth-step modes. By shorting jumper SJ2 the it can also be configured to be compatible with 3.3V micro-controllers that are not 5V tolerant. An on-board potentiometer allows for setting maximum drive current.
