LAN and Audio with the CM3

Thu Apr 11, 2019 2:51 pm

Hi all,

Making some changes to an existing product where we need to add LAN capability and audio, both output and input (mic).

With respect to the LAN interface, is there a particular advantage to using something like the LAN9512 over the ENC28J60? I have the SPI pins available, so I could go in either direction.

With respect to audio, I am planning on using I2S on pins 28-31 as outlined here:


Does anyone have any particular recommendations on I2S mics or amplifiers that have existing device-tree overlays? Also, any other issues with using pins 28-31 to be aware of?
