Who Knows!!?2 T4 needed for a line follower.. what's next?![]()
I think that now that SparkFun are doing the Teensy manufacture Paul will have more time to devote to new Teensy Ideas and projects.I'm just looking to see if there are any new developments, hardware or software.
The only “new” developments to the hardware have has been the SDRAM DevBoard - But thats an open source members project sponsored by @Dogbone06 and not an official PJRC development.I'm just looking to see if there are any new developments, hardware or software.
A bit of overkill for sure2 T4 needed for a line follower.. what's next?![]()
Anyone here know what the deal is with Sparkfun not ever having T4.1's available? Specifically the no header, no eth variety. I've visited several times in the last few weeks and they are always listed as on backorder.. I keep having to buy from Adafruit and/or Mouser but I would like to get the better discounted 25+ pricing from SparkFun. Oddly, Mouser shows plenty of stock on the Sparkfun Teensy Part #s but are priced much higher with no qty discounts..

I did notice a designator on the PCB that changes from time to time. Not sure if this is a PCB fab lot code or something. It is different also under different batches of PJRC product. Looking at 3 different lots just now, I see this marked as C4, C2 and A6. This C4 marked board happens to be a Sparkfun board.
Are you referring to the six-part sequence of longer and shorter lines next to the micro USB connector? If so, I was wondering what they’re for?Wonder what they'll do with the PCB silkscreen bit hashes by the USB connector maybe?
Yes, that. Paul once noted IIRC that was to ID the PCB maker? ... I found three here and they all had the same hashes with 1062 dates: 2117, 2007 - the third recent from @KenHahn is screwed back under display.Are you referring to the six-part sequence of longer and shorter lines next to the micro USB connector?
