Data Sheet

[Fig. 11 – Power supply of the logic circuits from a separate source]

Here, the BT1 voltage source can range from 0.01V to 32V as it does not power the board.

Connecting motors

This board can be used to control brushed DC motors or UniPolar Stepper motors (which have

5, 6 or 8 wires).

Connecting DC motors

[Fig. 12 – DC motor wiring diagram]

When connecting DC motors, we definitely recommend adding high-speed diodes for FlyBack

currents, for example Schottky diodes 1N5822 or 1N5819. This will prevent damage to the PS

and unnecessary tripping of protections. The maximum load for the diode will be created by a
