Generic HS-S43P Touch Button Module - Capacitive Touch Sensor, PH2.0 Connector

The HS-S43P module is designed to operate on a DC supply voltage of either 3.3V or 5V, making it directly compatible with most common microcontroller platforms like Arduino, ESP32, and Raspberry Pi (using 3.3V logic). Ensure your power source provides a stable voltage within this range.

The output mode is configured by soldering a Jumper connection on the module's PCB. Soldering the two upper short-circuit points sets the module to 'switch' (toggle/latching) mode. Soldering the two lower short-circuit points sets it to 'button' (momentary) mode. Only one pair should be soldered at a time.

Yes, the capacitive sensing principle allows the HS-S43P to detect touch through non-conductive materials like plastic, glass, or acrylic, provided the overlay is not excessively thick. Sensitivity decreases with increased material thickness, so testing with your specific cover material is recommended.

Mount the module using the two provided screw holes to secure it to your enclosure. It is critical to maintain a small air gap between the back of the PCB and the mounting surface to prevent parasitic capacitance from causing false triggers. Avoid direct handling of the touch pad during operation to prevent overheating.

The module features a standard PH2.0 pitch connector for power and signal output. This common connector type allows for easy wiring with pre-made Jumper cables, simplifying integration into breadboards or connection to microcontroller GPIO pins.
