I want to build a home-made multi-room home sound system.
I'm looking for a single board computer device with a minimal hardware configuration. In my thoughts, my only requirements are:
- Wi-Fi connection;
- Audio output;
- Push button to config wireless network through WPS;
- An LED to show current network status;
- Optionally, an RJ45 connection for development through SSH.
Actually no video output is required, nor additional USB ports.
What could be the cheapest solution for my needs?
