    Access to more GPIOs on Teensy4.1

    Ok, let me ask my question differently haha. Do you imagine having like a carrier board that is a ZIF daughter board? Or do you imagine having a carrier board that you can plug other zif cards into? I can't think of any other uses, if I'm missing something fill me in :)

    Access to more GPIOs on Teensy4.1

    This is a very interesting idea! I had originally vered away from dual pin rows because the stm32s drive me nuts when breadboardimg. I'd not considered soldering only the inside row male downwards for the breadboard, then soldering the outside row upwards to use jumper wires. That is very elegant!!!

    Access to more GPIOs on Teensy4.1

    I asked what your "purpose" for a ZIF socket was, you answered the question what "is" a ZIF socket.

    Access to more GPIOs on Teensy4.1

    For the connector, 2 of these would give 160 pins, which I think would be enough for the 128 or so pins, plus all the power and grounds. The important thing would be deciding on a form factor that could be consistent and easy to mate up to for carrier boards. The biggest downside I see to these...

    What would your purpose for the ZIP socket be?

    Access to more GPIOs on Teensy4.1

    Mind sharing your schematics/pcb layout with me? I've decided to go full steam ahead on this, and the more I have to copy for layout the better. It looks like it needs to be at least a 6 layer board, maybe an 8. and I'm going to design something like the micromod, as universal as possible so I...

    Symbols for KiCAD 8 of the MIMXRT1062DVJ6B

    Wow, this is awesome! Would you be willing to share this?

    Access to more GPIOs on Teensy4.1

    I also have a use case that could benefit from more pins. I previously posted about the idea of a Teesny 4 Max design to expose ALL of the pins, but I was pointed to the Teensy Micromod and it is working great EXCEPT, I still need more pins. It sounds like there might be more interest than just...

    AD7606p16_t4 library v0.0.1

    Yes it is! I wrote this library to always read all 8, and you just use the ones you need. I'll add a counter to the example so people can see for themselves, thanks for the idea.

    AD7606p16_t4 library v0.0.1

    AD7606p16_t4: Ultra-High-Speed 16-bit Parallel ADC Library 🚀 200K+ conversions/sec while main loop still runs 11M+ cycles/sec I built this library for 8-channel, 16-bit ADC applications using the AD7606. What makes it special: direct GPIO port manipulation for blazing performance that barely...

    Meet Teensy 4 Pro

    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!

    Meet Teensy 4 Pro

    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!

    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...
