Infineon Technologies IoT Sense Expansion Kit (CY8CKIT-028-SENSE)

Infineon Technologies IoT Sense Expansion Kit (CY8CKIT-028-SENSE) is a low-cost, Arduino™ UNO compatible shield board that can be used to easily interface various sensors with the PSoC™ 6 MCU platform, specifically targeted for audio and machine learning applications. The IoT Sense Expansion Kit includes two PDM microphones and one analog microphone. The Expansion Kit also includes multiple sensors to generate input data to feed ML algorithms, such as a 9-axis absolute orientation sensor and pressure and temperature sensor.

The Infineon Technologies IoT Sense Expansion Kit can plug into any Arduino UNO compatible development board from Infineon. The IoT Sense Expansion Kit is specifically designed to be used with the CY8CKIT-062S2-43012 or CY8CKIT-064B0S2-4343W Development Kits. The
CY8CKIT-028-SENSE does not include a programmable device on the board, but it does feature a configurable audio codec that uses I2C as the configuration interface.
