REM: It is a test project for me to learn the basics of CircuitMaker. I don't plan on making the board and test the design so USE AT YOUR OWN RISK !!!
- A 2-pin jumper has been placed to connect the supply pin VMOT of the motor driver to the 5V rail. This is because stepper motors need their own separate power supply ( typicaly 12V, supplied through the DC barrel connector) to get enough current and voltage. If you are using stepper motors, remove the jumper and connect a suitable power supply to the DC barrel connector. If you are driving DC motors, you can maybe put he jumper on, letting you use the 5V supply of the arduino board (check your current spec beforehand, the board cannot deliver more than 0.4A).
- A 3-way, 2.54 pitch terminal block has been integrated to the design in order to connect a a temperature probe to the board
- If you are using a 4-wire bipolar stepper, connect each phase to port A ( AO1, AO2) and port B (BO1,BO2). If you have a 5-wire bipolar stepper motor, do the same and connect the common wire to the middle GND of the terminal block.
-If you are using a servo motor, connect it to one of the two 3pin connector provider ( check polarity)
