BB-A4983 is a two-channel bipolar stepper motor driver that operates in full-, half-, quarter-, eighth- and sixteenth-step modes with an output drive capacity of up to 35V at ±2A load. The board can also power gear motors. It accepts DC supply voltage in the 8V to 35V range. Logic voltage can be between 3V and 5.5V.
Arduino, Pinguino and Maple can be used to control motors via this board. The spring contacts allow easy connect/disconnect of motor cables and power supplies. Jumper wires can be used to connect to Arduino/Maple/Pinguino/Duinomite-compatible boards.
The demo code package for the OLIMEXINO-85 includes an example for using this stepper motor driver under the Digispark Arduino distribution.
