Nothing more to add except that it would be awesome if I could simulate some of the teensy MCUs Is your feature request related to a problem? Please describe. I would like to simulate some of the teensy MCUs

Describe the solution you'd like Add some of the teensy MCUs (doesn't have to be the latest)

notes I know there is a feature request for the teensy 3.2 and it's hard to implement the hardware but I will wait patiently if you approve this
