Overview

The LDC2114EVM (Evaluation Module) demonstrates the use of inductive sensing to detect a button press on a monolithic piece of metal. The EVM can connect up to 4 buttons using the LDCTOUCHCOMCOILEVM or customized coils designed through Webench. Button presses & levels of pressure are indicated by onboard LEDs to indicated through onboard LEDs. The device can also be configured at different duty cycles to reduce power consumption.

Features

<7µA at 0.625 samples per second
Up to 4 buttons supported
Dedicated button logic outputs
Integrated and configurable algorithms for button press detection

USB A - micro USB cable
Sensor interconnect cable WM11299-ND
