- Solder header pins into the stepper driver board, making note of TOP label. Insert header pins on bottom of board so that the long unsoldered header pins point down when the TOP label faces up.
- Expose one side of the thermal adhesive tape and attach to the bottom of the heatsink. Trim tape so it does not extend beyond heatsink edges.
- Expose the other side of the thermal adhesive tape and attach the heatsink to the stepper driver board on the side with the TOP label.
- Solder surface mount and through hole components onto the pcb.
- Insert stepper driver board into pin receptacles.
