teensy4.1 vs 3.5/3.6

[ninja2]

Is the teensy 4.1 footprint pin-compatible with teensy 3.5/3.6?
I'm looking at Tindie's 3.5/3.6 breakout as they don't seem to offer a 4.1 version, thanks

Teensy 4.1 is the same form factor and very similar pinout, but not 100% identical. You could probably use that breakout board and simply not make use of the pins for the bottom side.

I wrote this list about Teensy compatability several years ago:

• https://github.com/TeensyUser/doc/wiki/Teensy-Compatibility

That compatibility description = just what I need, thank you

I forgot to mention, I did a google spread sheet on various microprocessors:

• Spreadsheet: https://docs.google.com/spreadsheets/d/1LSi0c17iqtvpKuNSYksMG306_FpWdJcniSRR6aGNNYQ/edit?usp=sharing
• The first sheet tries to compare each of the pins in common layouts
• The second sheet tries to give an overview of each Teensy
• The third sheet tries to give the pins used for various Teensy shields
• Other sheets compare the QT PY processors, ItsyBitsy processors, feather processors, feather wings, etc.
