Hello all,

Does anyone have a comprehensive understanding and/or experience with what can be used with the T4's gpio that goes in line with anything from any other product? Such a hats or shields? Surely there must have been some consideration taken in account when designing the board such that there has to be at least a few products cross-compatible...

Any thoughts?

Hello.
I do not have a T4 board, but there is an M4.
If you first look at the comparison of the GPIO connectors of these boards, they are similar, the chip is obvious too.
To begin with the question - what exactly do you want to get from the GPIO?
If you look at this thread - https://www.friendlyarm.com/Forum/viewtopic.php?f=61&t=1914, you will see some results of my experiments with GPIO.

Sincerely, Pavel.
