LDC1314 Evaluation Module for Inductance to Digital Converter with Sample PCB Coils


Order now


The LDC1314 evaluation module demonstrates inductive sensing technology for sensing and measuring the presence of a conductive target. The evaluation module includes two example PCB sensor coils that connect to the four channels of the LDC1314, and an MSP430 microcontroller is used to interface the LDC to a host computer.

This module is designed to provide the user with maximum flexibility for system prototyping. The LDC1314EVM is perforated at two locations:

  1. Between the PCB sensor coil (LC tank) and the LDC1314
  2. Between the LDC1314 and the MSP430 interface

The first perforation gives the user the option to snap off the PCB coils from the module and experiment with custom sensor coils, and the second perforation allows the user to connect the LDC1314 and sensor coils to a different microcontroller system or use multiple sensors in one system. An accompanying GUI allows for maximum flexibility and quick system prototyping.
