The TTP224 4-Channel Digital Capacitive Touch Sensor Module is a compact electronic board that detects touch through a capacitive pad, giving you a clean digital output without any moving mechanical switch. It is a favorite among makers, hobbyists, and students building DIY electronics, smart switches, and automation projects, and it pairs easily with Arduino, microcontrollers, and other control boards. With four independent touch channels on a single module, it is ideal for adding modern touch controls to small projects and prototypes.
Key features
- Capacitive touch sensing with no physical button to wear out.
- Four independent digital touch channels on one board.
- Digital output that connects simply to common microcontrollers.
- Compact, lightweight design that fits tight prototype layouts.
- Based on the widely used TTP224 touch controller.
Typical uses
- Touch-activated switches and control panels.
- Arduino and microcontroller learning and prototyping projects.
- Smart-home and automation experiments.
- Interactive DIY gadgets and student electronics kits.
How to choose / tips
- Confirm your project needs multiple touch inputs - the four channels suit multi-button panels.
- Check that your controller's logic voltage matches the module before wiring.
- Keep the touch pads clear of metal and moisture for steady response.
