Airlift bitsy vs airlift breakout for m4

by pauljk on Tue Aug 11, 2020 4:58 pm

If I have an itsy bitsy m4, can anyone offer advice on whether to buy an Airlift bitsy or airlift breakout for it?
I will be programming in c/c++ and not python. My questions:

1) are both supported by the same c libraries?
2) if using the airlift bitsy, will the proximity of the wifi signals interfere will adc readings on m4 analog pins?
3) if using the airlift breakout, my spi wires would be longer (than pins of a backpack, of course). Would/could this affect spi reliability?
4) any other pros/cons of going with one over the other?

My main thought was if wifi signals affected adc readings, then using the breakout, I could (attempt) to separate the breakout and shield the m4 from it, but doing so would lengthen the spi lines.

Thanks!

I can't see any reason to choose one over the other apart from physical constraints of your enclosure and mounting. While I haven't used the Bitsy, I've used the featherwing and breakout (with a Feather M4 Express before the airlift-wing was available).

Other than physical platform they are identical: same code & libraries.
