Custom StepStick for side mounting
this is a StepStick I've altered so that it can be side mounted to take up less board space. Constraints are that stepping is controlled by pin ms3 and so is either full stepping or 1/16 micro steps. Both sleep and reset are linked together so power control is through the enable pin. GND, VMOT and VDD are run to the board through extended header pins. The motor connections are free and pluggable.
