Possiblilty of a longer feather format board

Post by samveen »

My introduction to the Arduino environment was the feather nRF52, with it's nice breadboard-able form factor, which I did not appreciate until recently(almost 3 years of ignorant bliss), when I discovered that the Arduino Uno that I got wouldn't fit on to a breadboard. A big Thank You to LadyAda for that, and for making the lives of newbies easier.

Having said that, while working on my BTLE Keyboard project, I wished that I had a few more I/O pins to play around with (maybe 22 to 24 instead of the current 18). The blue-pill form factor comes to mind (which is approximately 4 pins longer (20 to the 16 per side on the feather).

With that in mind, might it be possible for the better-than-good folks at AdaFruit to consider extending the feather spec to create a LongFeather which adds a few pins more while keeping compatibility with the existing feather-wings? While not much, you have at least one guaranteed customer for 3 pairs of nRF52832/nRF52832 LongFeathers.

In the meanwhile, you could use these to extend the pins.
They are inexpensive and easy to use.
