It uses the TTP223B IC, providing a stable digital output when a touch is detected. Ideal for replacing mechanical buttons in interactive 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\u003eIC\u003c\/td\u003e\n\u003ctd\u003eTTP223B\u003c\/td\u003e\n\u003c\/tr\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)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Mode\u003c\/td\u003e\n\u003ctd\u003eJumper selectable (momentary\/toggle)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;10µA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e~60ms\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-activated LED lamp\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eCapacitive proximity sensing panel\u003c\/li\u003e\n  \u003cli\u003eInteractive hidden wall switch\u003c\/li\u003e\n  \u003cli\u003eCapacitive piano keys\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with 3.3V and 5V systems like Arduino Uno, Nano, ESP32, ESP8266, and Raspberry Pi Pico. The module outputs a clean 0-3.3V or 0-5V signal depending on supply voltage. Common pairings include any microcontroller with a digital input pin.\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 pin. Keep wires short to avoid false triggers. Set the output mode using the jumper: A for momentary (high while touched), B for toggle (output state changes on each touch). No external components needed.\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.
