    Teensy as a Dongle

    I would like to be able to use a Teensy 2 in a "dongle" form factor. Is there any good source for a (solid, not cable) USB-A plug to USB-mini plug adapter? I haven't been able to find one. (Similar question for Teensy 3 and USB-micro adapter).

    I did see that one guy epoxied a USB-plug onto a Teensy as a replacement to the existing mini or micro receptacle, but would like to avoid that route for the time being

    Thanks,
    John

    Gotta Google for it...there's plenty of adapters out there, but it's a little difficult to find a reasonable price on a wide selection (so you can buy a bunch of random adapters and only pay shipping once!)

    Here's one from NewEgg...$1.69 plus free shipping. I think I'll buy a couple of these myself!

    I actually saw those on ebay as well, but if they are actually female ("receptacle") on the USB-A end, it's not what I need. It *looks* like a male ("plug") USB-A, but if so they are mis-labeled, and I can't tell for sure from the image.

    Thanks,
    John

    I think the NewEgg part is correctly labelled, it looks like the female USB-A connector which you normally find mounted in a PC. The male USB-A connector (as on a USB memory stick) does not have the springy fingers on the outer housing, that this one has.

    That's what I was thinking.

    I wish there was a Teensy with a USB-A plug form factor-- "teensy on a stick"

    Cool

    This might do, if you are willing to wait for delivery: http://www.ebay.com/itm/2pcs-X-USB-A...item3377477c55

    Here is one from a USA based seller: http://www.ebay.com/itm/USB-3-0-Type...item56500aa325

    Here is a version for the Teensy 3.0: http://www.ebay.com/itm/New-USB-2-0-...item20cde1babf

    This USB breakout board that might be useful: http://www.robotshop.com/productinfo...102&lang=en-US

    However, another approach suggests itself. Get the smallest mini-B to female A cable you can find, and/or get a normal one and slice it to size. On one side of your breadboard/pcb, put the teensy with the USB connection at the end. Attach the cable and loop the cable underneath the breadboard/pcb and then glue the female A side of the cable to the back end of the board, so you just turn the teesy around to insert it in the USB slot. Assuming the teensy is in a dip-24 slot soldered to the board, you can just remove the cable and teensy when you want to switch to something else. Something like this: http://www.robotshop.com/productinfo...102&lang=en-US

    With mini-B being deprecated, I expect you will need to look harder to find cables, etc.

    There are other microprocessors out there that are made as dongles.

    Not quite following that I'm looking for a small-as-possible dongle format. I'm thinking I will have to go this route: http://www.pjrc.com/teensy/projects/...ess_teensy.jpg

    Thanks!

    I'll like to second the request for dongle versions of the Teensy 2 and Teensy 3 Pretty please...

    [Someone who has just ordered a lot of adaptors similar to those linked above... wishing that he didn't need to]
