Product Description

The Red TTP223 Touch Module provides a seamless interface for microcontrollers like Arduino, Raspberry Pi, and ESP32. The board features a circular sensing area on the front and two sets of solder jumpers (A and B) on the back for user customization. It operates in a low-power "sleep" mode and wakes up instantly upon touch detection. Its small footprint and three-pin interface (VCC, GND, I/O) allow for quick integration into tight enclosures. The onboard status LED provides immediate visual confirmation whenever a touch event occurs.

Key Features

Contactless Triggering: Capable of sensing touch through materials up to 3mm thick.
Low Power Consumption: Ultra-low current draw makes it ideal for battery-operated IoT devices.
Configurable Output: Supports both Latching (Toggle) and Momentary switching behaviors.
Status Indicator: Integrated Red LED lights up upon touch detection.
Stable Performance: Features automatic calibration to adapt to environmental changes.

Technical Details

Pinout: 1. VCC: 2V-5.5V Power. 2. GND: Ground. 3. I/O: Digital Signal Output.
Logic Levels: Output voltage follows VCC (CMOS logic).
Mounting: Surface mount components on a high-quality FR-4 Red PCB.

Prototyping and Engineering Tips from Robogears

The Solder Jumper Configuration: You can change the board's behavior by bridging the tiny pads labeled 'A' and 'B':
- Jumper A (Output Level): Open = Active High (Default); Closed = Active Low.
- Jumper B (Mode): Open = Momentary (Default); Closed = Latching/Toggle.
Hidden Switch Design: If mounting behind a plastic panel, use a thin piece of non-conductive double-sided tape. Ensure there is no air gap between the sensor pad and the panel surface, as air significantly reduces touch sensitivity.
Power Stability: If the sensor triggers randomly, place a 10uF electrolytic capacitor near the VCC and GND pins to filter out ripples from the power supply, especially when using long jumper wires.

Package Includes

1 x TTP223 1-Channel Capacitive Touch Sensor Module (Red)

Disclaimer

This sensor is intended for use with non-conductive overlays. Do not place metal plates directly over the sensing area, as this will permanently trigger the sensor or cause it to malfunction. Ensure the supply voltage does not exceed 5.5V to avoid damaging the TTP223 IC.
