Overview

The BOOSTXL-CAPKEYPAD is a BoosterPack plug-in module designed to demonstrate the CapTIvate capacitive touch technology on the MSP430FR2522 microcontroller. It features a 12-key numeric keypad with integrated back-lighting and proximity sensing for low-power wake-up functionality. The board provides a standardized 40-pin interface to connect with MSP430 LaunchPad development kits.

Why Choose This Part

The CapTIvate technology on the MSP430FR2522 offers high noise immunity and supports operation through thick overlays or moisture. It includes integrated LED back-lighting for the keypad and allows for ultra-low-power proximity sensing to extend battery life in portable applications.

Applications

Access Control Keypads
Developing secure entry systems that require a durable, moisture-resistant 12-key numeric interface.
Industrial Human Machine Interfaces (HMI)
Creating robust control panels for harsh environments where physical buttons may fail.
Smart Home Security
Implementing low-power alarm panels that wake up from sleep mode using proximity detection as a user approaches.
White Goods Controls
Designing sleek, easy-to-clean touch interfaces for appliances like ovens or washing machines.
