You should explain this. CMOS is a very good digital buffer and bad analogue buffer /unless CD4066/4053, of course/....

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

Use of A0 is good to switch between two DAC. For more than 2, i.e. for 3 or 4 DAC, you may need CD4053.
You also may use selector lines, and...

Change it, exclude PD4 from setting. Never start initially with Motor ON.

switch IC Why, your AVR as a Master can do it without Nyquist. Use CD4053.
Mega328P NRND - WDF? 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).

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.
