This is the schematic for the PCB and the motors will be connected on the X and Y output pins from the drivers. The PCB also has a MOSFET control for a powerful servo or a spindle. It has inputs for limit switchees, for controling the spindle direction, outputs for 3 axis step motors and so on and is fully compatible with the GRBL platform. Each driver has jumpers for controlling the microstepping. Add capacitors for smooth voltage at the input. It has a reset buton as well and pins for 5V and 3.3V. It also has pins for i2c communication.
