TTP226 8-way Capacitive Touch Switch Module

Key Features:

✔ 8 Independent Touch Channels – Control multiple functions with a single module (e.g., lighting, menus, or IoT triggers). ✔ Adjustable Sensitivity – Fine-tune via onboard potentiometer (default: ~50pF trigger capacitance). ✔ Digital Output (High/Low) – Each channel outputs 3.3V (HIGH) when touched, 0V (LOW) when idle. ✔ Low Power Consumption – <2.5mA in operation (ideal for battery-powered projects). ✔ Wide Voltage Support (2.4V–5.5V) – Works with 3.3V and 5V systems (Arduino, ESP32, Raspberry Pi). ✔ Multiple Modes –

• • • Toggle Mode: Toggles output state with each touch (like a push-button).

    • Direct Mode: Output stays HIGH only while touched (configured via jumper). ✔ Compact PCB (50×30mm) – Easy integration into panels or enclosures.

Applications:

• • • Smart Home Panels – Touch-controlled lights, fans, or appliances.

    • Industrial HMI – Dustproof interfaces for machinery control.

    • Interactive Displays – DIY music players, gaming consoles, or art installations.

    • Replacement for Mechanical Buttons – No wear and tear over time.

Pinout & Wiring:

• • • VCC: 2.4V–5.5V power input.

    • GND: Ground connection.

    • OUT1–OUT8: Digital outputs (connect to microcontroller GPIOs).

    • A0/A1 Jumpers: Configure mode (toggle/direct/lock).

Package Includes:

• • 1x TTP226 8-Channel Touch Module.
