What "voltage signal" resistance can see any AVR?   Technically, it is possible to connect two AVRs, if the impedance of "voltage signal" is not too high.

A0 is realized either directly to the connector, or as an option. Blue board is better.

Why, your AVR as a Master can do it without Nyquist. Use CD4053.

They are Active, come also in 3.3V version (beware of not damaging it with 5V AVR).

To add to your DIP nightmares, may I add QFN packages. Arduino's lovers may say the phrase "non è un granché" (It's nothing special/not a big deal).
