    Post#8 above links to SFun page with docs, details and links

    sparkfun.com/tutorials/getting-started-with-micromod

    Indeed boot might be PGM, and reset might be On/Off - but 'it seems' like the 1062 doesn't offer a reset as used in conjunction with Teensy bootloader

    I thought for the fun of it, I would update my Excel document to add some pages for this one, as an idea of seeing what things in the sources and libraries might need to be updated. There are some interesting things I found when mapping all of the pins, which include:

    Again looks like common pins for 1-33 with T4.1. 34-39 are the SDIO pins. And 40-45 are new.

    Some interesting things include:
    We can create a Wire3 object for the new (hardware I2C 2 object which does not have pin exported for T4 or 4.1)
    All of these pins can probably be made PWM pins with Quad Timer. There are some duplicates. like QT3.1 is on pins 18 and now 43)
    FlexIO: All of these pins are on FlexIO 2, which is nice as it has DMA

    But maybe an interesting thing with these pins. Is I believe we now have all of the IO pins associated with 8 bit parallel LCD display sub-system. Which I think I marked up all of these in my last column

    Strange that the release is hold off (by sparkfun?). The new Raspberry Pi RP2040 got announced alongside MicroMod boards.

    Strange delay indeed. Assuming PJRC did their part the holdup may be on the SparkFun side? Maybe SFun PCB build with 1062 or the Pre-Order RP2040 bumped it, or release for this SparkFun LoRa Thing Plus that just showed up in email today ... or some other board of the week/month in development?

    Maybe it is/was waiting for the T4.x bootloader chip to be released?

    After all there is only one Paul, and with PJRC being down to just him and Robin due to the virus and distancing rules, I imagine he made the decision to come out with the bootloader first. There has been a steady clamor for it since the Teensy 4.0 was announced, while I don't know what the market for micromod Teensys might be.

    I could also imagine perhaps there is one or more parts that he just couldn't source ASAP. Unfortunately, with Chinese New Year starting on February 12th, it may make other supply chain issues hard for the next few weeks.

    Since it appears to have the required display pins and there is no development going on, I assume Paul or someone else has already selected a display and has working code(??)

    A micromod Teensy 4 seems really interesting, im guessing it wont come with a ethernet PHY, would it be as simple to add a DP83825I to the carrier board and then just use the native Ethernet lib?
    Also really hoping we will get a Teensy 5 micromod!

    I could be completely wrong, but I doubt it. At least I don't see anything in the micromod pins or carrier boards that mention Ethernet.

    As for a Teensy 5 MicroMod not sure what that would be. I am pretty sure from the future Teensy thread that next or future Teensy mentioned will be a released as a 4.x...
    But who knows Paul could surprise us

    oh yeah, sry. i mean the IMXRT1170 teensy. dont know why i just assumed that the IMXRT1170 teensy would be called teensy 5...
    hmmm seems like a shame to not get ethernet on the micromods, but then again, not many users need it, just happens that i need it
