A3967 Stepper Motor Driver For Arduino

This A3967 Stepper Motor Driver ForArduinois the latest version of EasyDriver v44 co-designed with Brian Schmalz. It provides greater flexibility and control over yourstepper motorcompared to the older versions.

It is a simple to usestepper motor driver, compatible with most microcontrollers that can output a digital 0 to 5V pulse (0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The module requires a 7V to the 30V power supply for amotor. The module has an onboard voltage regulator for the digital interface that can be set to 5V or 3.3V.

Connect a 4-wirestepper motorand a microcontroller and youve got precision motor control!EasyDriver drives bi-polar motors and motors wired as bi-polar. i.e. 4, 6 or 8 wire stepper motors. Themicro stepselect (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the micro-stepping resolution.The sleep and enable pins are also broken out for further control.

Note:Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to t
