I2S Dacs and the Raspberry Pi

Let’s start with some nice schematics ¬†showing the connections needed:

 

– Raspberry Pi model B

raspberrypi_i2s_p5-1

 

raspberrypi_i2s_p5_2

 

 

– Rasbperry Pi model B+ and model 2

raspberrypi_B_plus_i2s_1

 

raspberrypi_B_plus_i2s_2

 

 

In order to configure I2S dacs is pretty straight forward. Just edit /boot/config.txt, enable the overlay for the dac of your interest and reboot!
