EasyDriver Stepper Motor Driver Board

EasyDriver Stepper Motor Driver Board is a simple stepper motor driver for digital pulse control. It works with devices that can output a 0 to 5V digital pulse, and it can also work with a 0 to 3.3V pulse when SJ2 is soldered closed. The board includes an onboard voltage regulator for the digital interface. It can be set to 5V or 3.3V. It drives bi-polar stepper motors and motors wired as bi-polar, including 4-wire, 6-wire, and 8-wire stepper motors. Version v4.4 fixes the silk error on the min/max adjustment.
