4-input Touch Pads

touchpad module (touch switch) capacitive touch sensor chip based TTP224. The module supports up to 4 channels, touch input, in which each of the sensor channels have a high sensitivity to the human touch.
The output of this module is a TTL signal, so you can easily connect this module to a microcontroller (Arduino, MCS-51, AVR, ARM, etc.).

- Working Voltage: 2.4 - 5.5 V
- Chip Sensor: TTP224
- Number of Channels: 4 Channels
- Interface: TTL
- Sensing Type: Capacitive
- Features: Equipped with a built-in LED as an indicator of the output signals from each channel touchpad
