RepRap optical infrared limit switch, equipped with a TCST2103 sensor, intended for detecting the home position and limiting axis travel on 3D printers and CNC machines. Its operation is based on an infrared optical barrier formed by an emitter LED and a receiver phototransistor, placed face to face on the two arms of the sensor. When a flag mounted on the moving axis enters the sensor slot and interrupts the infrared beam, the module output changes its logic state, signaling the control board that the travel limit has been reached. As a contactless system, there is no mechanical contact wear and no debounce effect specific to microswitches, which provides better homing repeatability compared to classic mechanical limit switches.
The module comes with an 800mm cable and connector, ready to connect to the control board, and has three pins for power, ground, and signal. It is compatible with Arduino boards (UNO, Nano, Mega), as well as common 3D printer and CNC control boards such as RAMPS 1.4, MKS, Melzi, or other platforms that accept digital endstop inputs. Many versions also include a status LED that visually indicates when the beam is interrupted, useful for mechanically adjusting the sensor position. The board is easy to mount through the PCB mounting holes, and the flag that interrupts the beam can be made from a simple 3D-printed part or a thin sheet of metal.

| V | +5 V supply | 5 V |
| G | Ground | GND |
Usage:
Mount the module on the machine frame, aligned with the axis travel limit, using the mounting holes on the board.
Install a flag (tab) on the moving part of the axis so that it cleanly enters the sensor slot without touching its arms.
Connect pin V to 5V, pin G to GND, and pin S to a digital pin of the development board or to the corresponding endstop input on the control board.
Power the system and check the status LED or the signal pin reading by manually moving the flag in and out of the sensor slot.
Configure the endstop logic in the firmware (Marlin, Klipper, or other firmware), reversing the state if the switching direction does not match.
Run a home command on the respective axis and verify that movement stops correctly at the desired point.
Fine-tune the module position on the frame to set the exact home position of the axis.
