TTP224 - Touch 4Channel (Big)

🔍 About This Module:

The TTP224 touch sensing IC, which provides 4 capacitive touch inputs. It replaces mechanical buttons with touch-sensitive pads and is ideal for use with microcontrollers like Arduino, ESP32, Raspberry Pi, etc.

🧩 Pinout:

From left to right on the header pins:

1. VCC – Power Supply (2.4V–5.5V)

2. GND – Ground

3. OUT1 – Output of Touch Pad 1

4. OUT2 – Output of Touch Pad 2

5. OUT3 – Output of Touch Pad 3

6. OUT4 – Output of Touch Pad 4

⚙️ Onboard Components:

• TTP224 IC – Main touch sensor controller

• Big Blue Touch Pads labeled 1, 2, 3, 4

• SMD Resistors/Capacitors – For timing and filtering

• Solder jumpers – For configuration (e.g., toggle between single-key/multi-key mode)
