It detects a finger touch on its sensing pad and toggles the output accordingly, requiring no physical pressure. The module handles the capacitive sensing, debounce, and output drive, making it easy to add touch input to Arduino, ESP32, or Raspberry Pi projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e2.5V – 5.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eDigital (high\/low), configurable moment\/latch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensing Method\u003c\/td\u003e\n\u003ctd\u003eCapacitive, single channel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e~60ms in low power, ~220ms in fast mode\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e15mm x 11mm (board)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;2µA (low power mode)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-esp32-touch-lamp\"\u003eTouch-controlled LED lamp – toggle on\/off with a tap\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eCapacitive secret switch hidden under a non-metal surface\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-knock-pattern-door-lock\"\u003eArduino-based door lock activated by touch pattern\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eProximity-based interactive art installation using the sensor's field\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe TTP223 module works directly with any 3.3V or 5V microcontroller board, including Arduino Uno, Nano, ESP8266, ESP32, Raspberry Pi Pico, and STM32. Its digital output drives a GPIO pin directly. It pairs well with relays, motor drivers, or LED strips for adding touch control without a mechanical switch.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3V or 5V, GND to ground, and OUT to a digital input pin. The on-board LED indicates touch. A jumper on the rear selects between momentary (touch-hold) and toggle (touch-latch) output modes. Keep the sensing area free of conductive paths; thin non-conductive overlays like acrylic or tape can hide the pad.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
