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:
This repository focuses on building an open and reusable platform around the chip.
/pcb → KiCad schematics & PCB layouts
/driver → Linux driver / interface code (WIP)
/tools → debugging and testing utilities
/firmware → placeholder (not included, see below)
The Si468x requires proprietary firmware provided by the vendor.
