Meet Teensy 4 Pro

I've been tossing around how to deploy my Teensy projects to harsh environments, like bolted to the side of my Cummins engine as an example. I want to be able to seal it to IP67 waterproof standards etc etc. It's quite difficult to do with a 4.0 or 4.1 due to lacking mounting holes, and pins exposing the programming USB pins. So I'm thinking about designing a pro version inspired by the Arduino pros, but with the far superior Teensy. Is anyone else interested in this? I made a YouTube short with my initial idea, id love any and all feedback.

 
Also you wouldn't need to move chips from a teensy onto your board. You can purchase the bootloader chip pre-programed from pjrc, all of the other parts are generic and can be purchased from anywhere.
 
Using 0.1"/2.54mm pins rows instead of SMD connectors would be easier to use on any proto board available.
After the proto phase, designing a carrier pcb for projects would be far easier by not using smd connectors.

4 small mounting holes would allow better fixing than relying on the pins. Let enough space around hole for screw heads, whithout copper tracks.

Main USB pins should be present both on the CPU board and the pins. With solder jumpers to select which one to use.
Micro-USB or USB-C connectors are not well suited when you have to connect/disconnect a large number of times.
And they are not suited for harsh environment.
USB connector on the MCU board could be any type, with preference for USB-C.

Integrate the PJRC bootloader chip, but expose the JTAG port on separate pins, with selection to use either the bootloader chip or the JTAG pins. The board would also be usable with the MCUXpresso IDE from NXP

Vin should accept about 5 to, let say, 9V. When using the board on any vehicle, a better input power design would be implemented on the carrier board.

That's all for today
 
Have you come across the Teensy MicroMod ? https://www.sparkfun.com/products/16402 Not quite as many IO as you propose but is already commercially available off the shelf
I hadn't come across this, thank you for sharing! As long as I can get at least 2 of the canbus's to work this should be perfect for my use cases. I can't believe I didn't come across this in my searching. I think I'll order up a few of these and see how it goes!
 
Oh man this is PERFECT, exactly what I was hoping for. SO glad I don't have to design my own and can just buy these!
