Description

There are a number of Step-Stick breakout boards to allow the nearly ubiquitous Step-Stick compatible controllers to control off-board drivers. But many off-board drivers like 5V and higher power. This is a simple board to provide a level shift and higher current(16mA) for off-board drives. The Step, Direction and Enable pins are sent to the Motor pins.
