    I am measuring the max rate that a stepper motor is driven at. Because steppers require acceleration and deceleration for best performance, the train of pulses does not have a fixed period. It was getting tedious to...

    Well, all the controllers on that list are based on the old 8-bit Arduino design and only support 3 Axes. Also, a lot of them don't have any isolation or noise control so EMI can cause problems like controller reset...

    As long as you are looking at headers, It would be great to find 2x3 2mm header+socket for the teensy 4.1 that works with the the 2.54mm pitch sockets. I've had real trouble finding ones that work together. The 2mm...

    Thank god this was a false alarm. The last thing I need is to deal with is customers not getting their stuff working because of counterfeit teensys.

    OK, that was good for a laugh. Over at EEVBlog there are several long threads about the Blue Pill Problem including some decapped STM32F103 showing that they weren't made by STMicro. I think they identified something...

    Amen to that. That's one of the reasons I based my CNC board on the T41. Another is that, unlike the BluePills and such out there, it is a totally consistent package. If you buy a BluePill today, you probably won't...

    Welcome! It's good to have another WA company building on Teensys. Looked at your store and see at least one Unicorn - reasonably priced 1x24 pin sockets! I usually just cut down 1x40s and hide the ugly end.

    You can also use Conn_01x24 in the Legacy Conn library. It doesn't have to be a socket but you do have to hook it up to 2.54mm pitch footprint - Pin_Headers:Pin_Header_Straight_1x24_Pitch2.54mm.

    It looks OK to me. It is fine to run the traces under the teensy. What kind of trace separation do you have there? Hard to tell from the image of the board. Unless you have to, I would not push the limits of your PCB...

    Well, I'm not sure how strict that is. The SFE docs say you don't have to adhere to the pinouts. Honestly, the same 2x3 ethernet header on the compute board would decrease my interest level. At least with the T4.1, I...

    I wonder if, instead of the 6 pin header, all the ethernet pins (R+, R-, T+, T- and LED) go through the micromod pins. They push USB D+ and D- through them so differential pairs are possible.

    Yes, wait and see is good advice. Though, having a product based on the T4.1, I am keenly interested in this development. I think I see the potential for a pony in there.

    In that case, a simple plug-in to read the voltage could be written. My breakout board has a serial port header on it so you could use that to get the tip voltage. Sounds pretty easy at first blush.
