描述
The US082-ZSSC3123EVZ board demonstrates the functionality and performance of the ZSSC3123 wide capacitive sensor. The board provides a standard Pmod™ Type 6A (extended I2C) connection for the onboard sensor to plug into any required MCU evaluation kit with a matching connector. The US082-ZSSC3123EVZ features Pmod connectors on both sides of the board to allow additional Type 6/6A boards to connect in a daisy-chained solution with multiple devices on the same MCU Pmod connector. With its standard connector and software support, the US082-ZSSC3123EVZ is ideal for rapidly creating an IoT system using the Renesas QuickConnect tools.
