Description

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.
