Teensies are awesome
Teensies are fantastic boards for projects that need a high clock speed unfortunately to make a Teensy an Xbox 360 controller third party libraries will be needed as the default framework hardcodes preselected USB description headers for specific devices. I needed a way to switch from one USB descriptor to another when sending a disconnect command out and I still haven't been able to use this device for that purpose however less dynamic USB connections work fine.

Work well in project for Intellivision flashcarts
I use these to power first generation RTO flash carts for the Intellivision. So far all three have worked as expected.

Small and quick.
It got the job done. Not much I can say about it aside from that.

Gotta love the Teensy 4.1!
The T4.1 is like an Arduino on steroids, yet still compatible with the IDE, plus PlatformIO. I've spent the past 6 years using the T4.1 to develop a midi controllable laser synthesizer to project abstract imagery from industry standard RGB laser projectors. PJRC's Audio Library and online object oriented Audio Design Tool is a game changer, especially for beginner programmers
