Key Features of TTP223 Touch Switch Module
- Capacitive Touch Detection: Senses finger touch through the onboard pad - no mechanical pressure needed, eliminating switch wear and bounce issues.
- Wide Voltage Range (2.0V-5.5V): Directly compatible with 3.3V and 5V microcontrollers including Arduino, ESP32, ESP8266, STM32, and Raspberry Pi GPIO.
- Ultra-Low Power Consumption: Only ~1.5uA in standby, making it ideal for battery-powered and energy-harvesting applications.
- Configurable Output Modes: Use onboard solder jumpers to switch between momentary (default) and toggle modes, and between active-HIGH and active-LOW output.
- Fast Response: 60ms touch response and 220ms release time for snappy, reliable interaction.
- Tiny Footprint: At just ~11x10mm, it fits into the tightest enclosures and PCB layouts.
- Simple 3-Pin Interface: VCC, GND, and SIG - connect and read with a single digitalRead() call. No libraries or complex protocols required.
- Clean Digital Output: No debouncing code needed - the IC handles signal conditioning internally.
- Proven reliability across thousands of maker and industrial projects
Perfect For
- Touch-Activated LED Lamp: Build a stylish desk lamp that turns on/off with a simple touch - use toggle mode for latching control and PWM for brightness levels.
- Smart Home Touch Panel: Arrange multiple TTP223 modules behind an acrylic or glass panel to create a custom touch interface for controlling lights, fans, and appliances via relays.
- Interactive Museum/Exhibit Display: Let visitors touch pads to trigger audio, video, or lighting effects - no moving parts to wear out.
How It Works
The TTP223 IC continuously monitors the capacitance of the onboard touch pad. When a finger approaches or touches the pad, the change in capacitance is detected and the module outputs a digital signal on the SIG pin. In the default momentary mode, the output goes HIGH while the pad is touched and returns LOW when released. In toggle mode (enabled via solder jumper), each touch alternates the output between HIGH and LOW - perfect for on/off switching applications. The module requires no external components and self-calibrates on power-up.
Wiring Guide
| Module Pin | Arduino / MCU Pin |
| VCC | 3.3V or 5V |
| GND | GND |
| SIG | Any Digital Input (e.g., D2) |
Tip: Allow ~0.5 seconds after power-up for the TTP223 to auto-calibrate. Avoid touching the pad during this calibration window.
