It detects touch through any non-conductive material (glass, acrylic) up to 5mm thickness. The module outputs a digital high signal when a pad is touched, with configurable modes (momentary or toggle). Ideal for adding touch controls to microcontroller 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\u003eTTP224\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e4 independent touch inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e2.4V – 5.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eDigital (Active High), configurable as momentary or toggle\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e~60ms in low power, ~100ms in fast mode\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;2μA at 3V\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\/touch-sensitive-switch-kit\"\u003eTouch-sensitive lamp or light switch\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e4-key capacitive keypad for password entry\u003c\/li\u003e\n  \u003cli\u003eTouch-controlled music player interface\u003c\/li\u003e\n  \u003cli\u003eInteractive art installation with proximity\/touch triggers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe module works with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, Mega, ESP8266, ESP32, Raspberry Pi Pico, and STM32. It communicates via simple digital pins—no library needed. Just connect VCC, GND, and the output pins to your MCU's GPIOs. Internal pull-up resistors are not required as outputs are active high.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3V or 5V, GND to ground. Each of the 4 output pins (OUT1–OUT4) goes to a digital input pin on your microcontroller. The module has onboard jumpers to set output mode (momentary or toggle) per channel. Ensure the touch pads are not covered by conductive material during operation.\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. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, the TTP224 module runs on 5V logic and can be directly connected to Arduino Uno's digital pins. No level shifting needed.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use it with a 3.3V ESP32?\u003c\/summary\u003e\u003cp\u003eYes, the module operates from 2.4V to 5.5V, so 3.3V logic is fine. Connect VCC to 3.3V on the ESP32 and the outputs will be 3.3V when active, safe for ESP32 pins.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I set it to toggle mode?\u003c\/summary\u003e\u003cp\u003eEach channel has a jumper pad on the board. Short the jumper for the channel you want in toggle mode (output changes state on each touch); leave open for momentary (active only while touched).\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
