OtterCastAmp

OtterCastAmp is an open-source Sonos Amp replacement, based on a Sochip S3 SoC and pulseaudio sink/source.

How do I get one?

We are currently planning a small batch production run, stay tuned. [editors notes: It is 2024 now and noone really expected how bad covid would affect the supply chain. While all parts are available again, we are only slowly getting interested in this project again]

You don't want to wait? You can of course run a small batch on your own! Please have a look into the gerber folder, a batch size of just 5 (and up to 30) boards is supported by JLC.

Installation & Configuration

After downloading and flashing the image, OtterCastAmp can either be configured via the config.ini file or via the web-interface.

Do you plan a PoE version?

Maybe. (25W of power is not enough and >50W isn't popular)
