Keyestudio RPI TTP229L 16-channel Touch shield for Raspberry Pi / CE certification

The Keyestudio RPI TTP229L 16-channel Touch Shield adds a versatile touch-sensitive keypad to your Raspberry Pi projects. Ideal for students, makers, and educators, this shield provides 16 capacitive touch keys to easily build interactive control panels and custom interfaces.

Sixteen capacitive touch keys

This shield expands your Raspberry Pi with 16 touch-sensitive keys, making it ideal for custom input interfaces. It is designed to fit directly onto your Pi, providing a neat and compact user-input solution.

I2C communication mode

The shield uses the I2C interface to communicate with your Raspberry Pi, minimising the number of pins required. This leaves the remaining GPIO pins free for other sensors and actuators in your project.

Onboard power indicator

Operating at a standard 3.3V supply voltage, the board features an integrated power indicator LED. This allows for quick visual confirmation that your shield is receiving power and ready to use.

Ready-to-use software resources

To help you complete your programmes quickly, the shield comes with an installation package and source codes. A comprehensive document is also provided to guide you through the setup process.

TTP229-LSF controller chip

Built around the TTP229-LSF chip, this board ensures reliable touch detection across all 16 channels. A dedicated wiki page tutorial is available to assist students and makers with step-by-step integration.
