The LDC2114EVM from Texas Instruments is a LDC2114 1.8V 4-channel inductive touch evaluation module. 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 indicate through onboard LEDs. The device can also be configured at different duty cycles to reduce power consumption.

• Less than 7µA at 0.625 samples per second
• Up to 4 buttons supported
• Dedicated button logic outputs
• Integrated and configurable algorithms for button press detection
• LDC is controlled by an MSP430 which interfaces to a host computer
