Frequently asked questions
How do I wire this motor to a microcontroller?
Plug the 5-wire motor cable into the ULN2003 board. Connect the board's IN1 to IN4 inputs to four digital outputs on your microcontroller, and connect the board's + and - pins to a 5 V supply and ground, sharing ground with the microcontroller.
Can the motor be driven without the ULN2003 board?
Yes. The 5-wire motor can be driven by a ULN2003 chip or equivalent driver, or by any driver that supplies the four coil phases in sequence. The included board simply provides the driver and a plug-in connection.
