Today I soldered the radio module for my rapsberry pi based car radio. This was the last soldering/electronic challenge for this project now I only need to finish the software (= easy) and the hardware problems (= somewhat outside of my comfort zone :-))
The audio board consists of a AR1010 breakout board from sparkfun that connects via i2c and a simple preamplifier for the radio signal. The 3 connector on the right side go to the analog audio out of the raspberry pi.
