Jerry,
You make a good point about being able to do software development right on the RPi.
In your opinion, what are the RFI concerns about using the Pi-Zero?

Indeed, the $2 Blue Pill has two 12bit A/D's, good to 1 msps, up to 16 channels.??
A 72mhz 32bit ARM processor, 64kbytes of flash, 20kbytes of SRAM, lots of IO pins
Runs on 3.3v, so no need for level shifters talking to an Si4432.
Totally blows the doors off a Nano in every way.

Documentation on the web telling how to program it is confusing.
No need to mess with special bootloader code for the USB port, you can program
any blue pill through the two pin UART port using a $2 CP2102 USB-to-UART dongle.
Read my old post here:

But I'd much prefer a $5 RPi-Zero.

Can do software development right on the RPi, has 3.3v IO pins that speak SPI,
and can drive anything from a $2 16x2 LCD to a 30" 1080p HDMI monitor.
Now on the RPi, the (nonexistant) A/D is definitely not up to the Nano spec.?
Though I don't see where the tinySA needs an A/D.
And would be easy to add an A/D as a peripheral if it is needed.
