Teensy 3.5/3.6 upgrade for uBITX

n5ib_2
 

Here's what our little Skunkworks has been up to.

A wee PC board that accepts a Teensy 3.5 or 3.6 processor, then plugs into the space that would have been occupied by a NANO.
Corresponding I/O lines are routed to maintain compatibility with uBITX.
Since the Teensy has a RTC (real time clock) there's a spot for its backup battery.

In principle, the adapter could be used to plug in a Teensy anywhere a NANO used to live.
On a stock Raduino (have to remove the NANO and socket the space), an enhanced Raduino, our own RadI2Cino, or what else may come along.
Scads more memory, more I/O including lots of analog, an on-card microSD slot, and of course the RTC
The Teensy 3.5 runs on 3-6 volts, with 3.3V logic, but 5 V tolerant digital inputs. The Teensy 3.6 also runs on 3-6 V, but its logic is 3.3V ONLY, and is faster and has more memory than the 3.5

Prototype boards are in hand are about to get to beta test within the next few days. Firmware portability is of course the thing that must be confirmed,
We'll keep y'all posted.
