No not all pins are freely available.
Unless you want to keep your own fork of the firmware updated with each release, you're best to pick an already included pin map.
Its not a simple ask to have your pin map included.
Serial 1 and 2 are also not available for serial interface with speeduino (Serial 1 is the native USB).
only Teensy 3.5 is officially supported.
as far as i know the knock interface isn't implemented, but i think the code is there, needs to be enabled in the INI file.

Thank you for your feedback.

@NickZ
I know that the 3.6 and 4.1 don't have an official support but as there is work going on to support them and i want get onboard.
This is exactly why I am here to find out what pins should I use to stay compatible with the work already done.
Its the last thing i want to keep my own fork for firmware.
Also if there is ongoing work for the knock interface over SPI than that is awesome. I will look into it.

There is no ongoing work to support the 4.1....

Why do you keep talking about it?

Josh isn't going to support it as it's completely overkill for Speeduino.

Hell he even made a video covering the subject.

Finished designing the first prototype.

If they arrive, ill let you know, how it goes.
I already have 2 people waiting to try it also.

Bit of an update:

Finished the enclosure design over the weekend (if you can call it that....).
The boards are already manufactured and are on the way, but there is a small issue with a lot of the chips that i intended to use...
Basically this project just got stopped in its tracks due to chip shortages.
8 different chips that are no longer available. Stock is either gone or the prices are 10X what they where 2 months ago.
Most of them have a lead time of 30 to 50 weeks.
I hope that these estimates are not correct.

So this will go on the back burner until this issue is resolved.
At least i have a cool paperweight until then.
