Optical Homing or PEC sensor PCB for OnStep

Optical switch on PCB with JST-XH 3 pin connector, cable included. Easily add homing to your project by attaching this board inside the mount. When combined with a 3D printed or sheet metal blade that covers 180 degrees of the RA axis rotation you will have a fixed home position that persists between power cycles. The sensor can also be used in a similar way as a PEC sensor when appropriately mounted to the drive mechanism (such as the worm in a worm/wheel gear drive).
