An I/O Processor (IOP) for the uBITX V5... a Teensy 3.2 microcontroller with Audio Adapter Shield, housed within the uBITX enclosure, to provide TX and RX Digital Signal Processing (as well as a single USB interface to the computer).
kill my Teensy 3.2. I unplugged the Teensy-to-Raduino comm lines in
order to program the Raduino. When I plugged them back in, I didn't
realize that I was off by one pin. So I believe something that
should've only gotten 3.3V, got more. No light on the Teensy.
This development effort, while it has been fruitful, is definitely
complicated. I don't think I have the bandwidth to continue it. I plan
on merging all the branches back to master, collecting the pieces-parts
of uBITX V5D, and calling it "done". I will rebuild my uBITX V5 back
into a relatively stock configuration, and use an external digital
interface (see KK5JY).
