Once the Nano is -almost- full, you can spend 90% of your time fooling around trying to make another feature fit.
Best to just go with one larger processor, if you add a second processor you then have to spend time getting them to coordinate.
Here's a possible upgrade: ?
I haven't tried one, but seems ideal. ?Lots of extra pins, flash, ram, 12 bit ADC's, processor power. ?And cheap.
This processor has 3.3v io like most modern parts such as the Si5351, not 5v like most Arduinos have.?
Not interested in having it make coffee, but plenty of other features that would be useful in such a rig:
? CW Keyer, ?SWR meter, battery monitor, stand-alone digital modes, diagnostic aids.
I think the Si5351 should be on the main Bitx40 (or uBitx) board, some filtering on those I2C lines. ?
Then we can have different off-the-shelf processors and displays, depending on the the feature set we want.
If you get noise in the receiver from the processor and display, that means it needs shielding and bypass caps and such.?

Now raduino use 95% of program storage space, so what is next¡ we can add one more nano in our transceiver or?
