Automotive 4-Channel Capacitive to Digital Converter Evaluation Module


Order now


The FDC1004Q evaluation module is used to evaluate the FDC1004-Q1, automotive 4-channel capacitive-to-digital converter. The evaluation modules features a breakable PCB composed of three sections: a USB to I²C converter based on the MSP430F5528 microcontroller, the FDC1004-Q1, and two sensor electrodes to demonstrate the sensitivity of the FDC1004-Q1. The sensor can be removed and replaced with custom sensors designed for your specific application, and the evaluation module's GUI can be used to configure the FDC1004-Q1 registers and display the measured capacitive values in four separate graphs.
