Which microcontroller modules are compatible?
ATMega1284(P)-based modules from Software & Circuits and Pollin (AVR-NET-IO modules, if the MCU is upgraded). Some run caffè!, some leva!, some ristretto!. Check the download page.

Can I have the firmware source code?
Source code is not made available. While the firmware is free, it is not open source.
