Idle stepper motor driver

SN754410 (1A continuous) or L293D (only 0.6A continuous, 1A peak, but with more durable internal clamping diodes than SN754410). Very easy to mount on VEMS genboard v3.x mainboard in 3 minutes if you want to control stepper motor, or other 4 independent output channels, max +-600mA load each ( this can drive to + or -, unlike the TPIC6A259DW that can only switch towards ground )
Note: assembled controller is equipped with this by default
