Could simply replace the Nano clone on the Raduino with a Raspberry Pi Zero.
Easier to keep all software on one processor, no need to communicate with another processor.?
Would need to port the uBitx Arduino sketch over to C on the Pi Zero, but that should be easy enough.
A high speed morse keyer might be off by a few milliseconds now and then due to
interrupts and Linux housekeeping, but I doubt most of us would notice.

The RasPi has heaps of GPIO too - I'm wondering if the likes of a 'zero' could take some of the 'control ' and display functions from the Raduino? Would/could I^2C tie them? There must be a heap of non-critical stuff not? absolutely dependent on the microprocessor immediacy? A zero-W could give Internet remote ops too! (or has that already been thrashed and trashed?)
