10piece set of TTP223B digital capacitive touch sensor modules, operating from 2V to 5.5V. Compact PCB modules that convert a fingertip touch into a clean digital output for easy connection to microcontrollers and control circuits. Key benefits mechanical switches with a durable, contactless touch interface to eliminate wear and reduce maintenance. Wide operating voltage range (2V to 5.5V) makes the modules suitable for both 3.3V and 5V systems and common microcontroller boards. Simple digital output provides fast, reliable detection and straightforward integration with microcontrollers and logic circuits. Small footprint and low power consumption allow placement in compact or battery powered projects. Important attributes Model: TTP223B digital capacitive touch sensor module. Quantity: 10 pieces per pack. Operating voltage: 2V to 5.5V. Interface: simple VCC, GND, OUT connections for easy wiring to controllers. Form factor: compact PCB module designed for breadboard or direct wiring. Material: PCB with surface mount components and touch sensing area. Performance: stable touch detection, suitable for repeated use and continuous operation. Compatibility Works with common microcontroller platforms such as Arduino and Raspberry Pi and other 3.3V or 5V logic devices. Compatible with custom circuits that accept a single digital input for on off control or interrupt signaling. Practical applications Home automation: a mechanical light switch with a touch sensor to create a sleek wall control panel or retrofit lamp controls. DIY electronics and prototyping: Use with Arduino or Raspberry Pi projects to trigger menus, mode changes, or user inputs without bulky buttons. Consumer products and kiosks: Implement touch controls for instrument panels, interactive displays, or small appliances where a low profile input is desired. What you get Ten TTP223B capacitive touch sensor modules, ready to wire into projects or mount on prototypes. Integration tips Connect VCC to the chosen supply voltage in the 2V to 5.5V range, ground to GND, and read the OUT pin on a digital input. For reliable detection, mount the module so the touch pad is exposed or beneath a thin nonconductive surface. Use the modules in both momentary and latching control schemes by pairing the digital output with simple firmware logic on your microcontroller. This set provides a practical, compact solution for adding responsive touch input to a wide range of electronic projects and control panels.
