stepper motor

First custom PCB

First custom PCB

This is my first working printed circuit board. I used the toner transfer method to draw the traces on the copper board. The purpose of this circuit board is to drive a stepper motor. This is a proof of concept for the final board version that will complete my equatorial mount project. The equatorial mount will […]
