Teensy 4.0 would likely work pin compatible for software, but the schematic shows it sending some 5v signals into it so not a straight swap (teensy 4.0 only takes 3.3v on it's i/o. I imagine you could make up a little board with level shifters to get what you want done. I just had a look around and I don't have the spares I thought i had. I must have 5 of them in projects somewhere.
