§ 02 — Description

Compact TTP223 Touch Sensor v1.0 module for building touch control panels, hidden buttons and original custom user interfaces. Contactless and reliable control: With no moving mechanical parts, there is no wear, providing practically unlimited service life. Sensing through barriers: The sensor can detect a finger touch through protective coverings made of glass, plastic, wood or acrylic. Easy to use: The board features an LED that indicates press status and a standard 3-pin header connector (SIG, VCC, GND) with 2.54 mm pitch. Features Chip: TTP223 (TTP223-BA6) Sensor type: Capacitive touch sensor Operating voltage: 2.0 V – 5.5 V DC (fully compatible with 3.3 V and 5 V logic) Output signal: Digital (SIG / OUT) Board dimensions: 24 mm × 24 mm Indication: Built-in SMD LED showing press status Connection contacts: 3-pin (SIG, VCC, GND) Sensing through barriers: Works through non-metallic surfaces (plastic, glass, acrylic up to 3–5 mm thick)
