TTP223B Pre-Soldered Capacitive Touch Switch Sensor Module

TTP223B capacitive touch switch sensor module is a compact touch input sensor that detects a fingertip press on its touch pad and outputs a clean digital trigger for replacing mechanical buttons in interactive electronics. Based on the TTP223B touch IC, it is ideal for Arduino, ESP32, Raspberry Pi, and other microcontroller or GPIO projects that need simple human input for lamps, control panels, robots, wearables, smart home interfaces, and rapid prototyping. Use this capacitive touch module to add reliable single-touch control without moving parts, making it useful for sleek enclosures and DIY electronics builds. The header pins ship pre-soldered, so it works out of the box with no soldering required.
