Teensy 3.1/3.2 shortage (Design for Teensy 4.x?) #67

Closed NeusAap closed 1 year ago

NeusAap commented 1 year ago

Hello,

Since PJRC put a large disclaimer on their website regarding the stock and supply of the NXP chip on Teensy 3.x's & Teensy LC (see: https://www.pjrc.com/store/teensy32.html), I was wondering if anyone has already thought about, or maybe even designed an alternative design using the Teensy 4.x platform.

I would guess this would be possible, since their pinouts and capabilities are almost identical, but I just had not found any information about this yet :)

If anyone has done such thing, please let me know. And if not and I'd decide to do this I'll also share it ofcourse.

Kind regards, NeusAap

See further details in this thread, but: I'm currently working on a successor, based around RP2040, with on-board USB-C, and with all components designed for pre-build. Current status is: I have everything but I2C working.

There's no new functionality. The purpose of the project is to make it possible to make these things again, and with a chipset that's readily available.

Teensy 4.0 would also be possible, but it's a hugely overpowered chip for what the board is capable of, and I personally think there's a better approach.

Of course: a Teensy 4.0 fork is perfectly possible, and the licensing (and open-source nature) of this project mean anyone is free to work on it.

Awesome. Sounds like a great idea! Probably way better choice to use RP2040 stock wise and price wise. Can't wait to your new design! Might have to make 2 versions then. I've found one Teensy 3.2 laying aroung my house, so I'll start building that one first :)

Thanks for the answer!
