library can set microstepping and generate the signals for each of the support driver boards high rpm plus high microstep combinations may not work correctly on slower mcus there is a maximum speed achieveable for each board especially with acceleration on multiple motors at the same time motors 4 wire bipolar stepper motor or some 6 wire unipolar in 4 wire configuration leaving centers out or

varies from motor to motor check motor coils schematic 100uf capacitor between gnd vmot make sure to set the max current on the driver board to the motor limit see below have a motor power supply that can deliver that current make sure the motor power supply voltage is within the range supported by the driver board set max current the max current is set via the potentiometer on board turn it while measuring voltage at the passthrough next to it the formula is v i 5 r where i max current r current sense resistor installed onboard drv8834 or drv8825 pololu boards r 0 1 and v 0 5 max current a for example for 1a you will set it to 0 5v for latest info see the pololu board information pages code see the basicstepperdriver example for a generic driver that should work with any board supporting the dir step indexing mode the microstepping example works with a drv8834 board for example to show what is possible here is the clockstepper example that moves a stepper motor like the seconds hand
