The optical endstop is a reliable and versatile endstop / switch for 3D Printers, CNC machines and other tools. Its innovative design is based on optical transmission, making it noiseless and ensuring a long lifespan of over 100,000 uses. Additionally, it is compatible with the RAMPS 1.4 board.

RAMPS is short for Reprap Arduino Mega Pololu Shield, it is mainly designed for the purpose of using pololu stepper driver boards (similar to 4988 driven board). RAMPS can only work when connected to its mother board Mega 2560 and 4988/DRV8825.
