Power Connection

Users should connect the recommended wall adapter, power supply to the DC barrel jack on the ProDriver. REMEMBER to disconnect the power before connecting/disconnecting your motor.

Input Control Pin Connections

The input control pins need to be connected to a microcontroller. To utilize the Arduino examples below, without modifying the code, we recommend using the SparkFun RedBoard (Qwiic) as the microcontroller. Use the table and image below to hookup the SparkFun RedBoard to the ProDriver with some jumper wires.

Note: Don't forget to ground loop the ProDriver to the RedBoard as illustrated in the image above.

Motor Channel Output Connections

The output channels for the H-Bridges need to be connected to the stepper motor. Users need to hookup the wire pairs for each coil to individual channels. However, the polarity of the connections isn't very important as the direction of the motor rotation can be controlled in software. For the recommended stepper motor, use the table and image below to hookup the motor to the ProDriver.

⚡ Note: Do not connect or disconnect the motor while the ProDriver is powered; as it may damage the ProDriver.

Motor Coil Pairs

In order to determine the wire pairs for each coil on their stepper motor, users can refer to the datasheet for the stepper motor. Often, the relevant information is indicated as shown in the diagram below.

For a 4-wire motor, users can alternatively use a multimeter to determine the wire pairs for the coils. This is done by comparing the resistance of one wire and against each of the three remaining wires. Whichever wire shows the lowest resistance against the first wire is the pair mate. The remaining two wires should show similar resistance between the two of them.

Single ProDriver

Utilizing the instructions above, an example of the standard assembly used for most of the examples in the Arduino library, is shown below.

Multiple ProDrivers

For users interested in utilizing multiple ProDrivers, we have provided an additional Arduino example for hooking up two ProDrivers in parallel. Use the table and image below to hookup the SparkFun RedBoard to the two ProDrivers with some jumper wires.

Note: By connecting the ProDrivers in parallel, they will need to be operated sequentially; they cannot be controlled simultaneously.
