From the project

Si468x-based DAB/FM receiver module (M.2 E-Key) with open hardware and Linux integration.

Open-source DAB/FM receiver module based on the Silicon Labs / Skyworks Si468x series.

This project provides hardware, software, and documentation to integrate a modern digital radio receiver into automotive and embedded Linux systems.

The Si468x is a highly integrated broadcast receiver supporting:

- DAB / DAB+ - FM (RDS) - Digital audio output via I2S - Control via SPI / I2C
