Build a photogate interface with this bare PCB for the GP1A57HR photo interrupter. It exposes power, ground and signal connections, with the intended circuit changing signal state when an object blocks the gate. The illustrated assembly is a reference, so the sensor and current-limiting resistor must be supplied separately.

Before you buy

Check the schematic and resistor selection before assembly; the photo interrupter is not implied included.
