Texas Instruments  LDC2114EVM

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.
