HI Jack,
Have you considered the Asus Tinker board?? Same form factor as
Rpi but even more capable.? Does cost more as well.? Quad core
1.8GHz, 2 Gb memory, Gb ethernet, 24 bit 192khz audio, GPIO, WiFi
& Bluetooth.
Cheers,
Will,

I said almost the same thing a day or two ago...it has some
really nice features, like a 12-bit ADC (4096 instead of
1024). Another important plus is that it can be programmed and
run in the Arduino IDE.

In keeping in line with Farhan's $100 goal for the
Transceiver, I would seriously look at using the
"Protoneer" mentioned by some others. It has the
"Nano" form factor, is Arduino Zero based, runs at 3x
the Nano speed, has 8x the Nano flash memory, 16x the
Nano RAM, and has a DAC. Seems like that is a great
opportunity to sweep in some open source code like
that K3NG has for his keyer, other modes of operation,
and many, many, more features over time. 256KB of
flash memory is a LOT of available space. The
Protoneer is $10 and you can get a group together to
save on the $5 postage from NZ. I'm sure there are
plenty of firmware writers out there.
