Description: USB On-The-Go is a really useful USB specification! It allows some small devices that would usually be unable to act as a host to have limited hosting capabilities! USB-OTG is common for things like tablet computers and smartphones in order to allow for USB peripherals like flash-drives, keyboards, etc. to be hooked up.

If you have a USB OTG device, you need one of these Female A to Micro-A cables to act as a host. Remember, not all devices are USB-OTG compatible, so make sure that whatever you’re plugging in actually has this ability so you don’t damage something!

Dimensions: 4" long

Customer Comments

  • BE CAREFUL! I looked at this thinking it would work out of the box for most Android phones and tablets but NO! Most android smart devices have USB micro B ports, not micro A ports. It will be better for you and your wallet if you just hack 2 cables into 1 instead of mistake this particular cable for the one you want. If this were a micro B cable, I would gladly buy a truckload and distribute them to my friends.

  • So, what devices actually use micro A? I was excited about a Sparkfun OTG cable, then I realized I have never even seen micro A before.

  • FYI: The micro-a plug on this cable is not compatible with the micro-b jacks on cell phones like the Galaxy Nexus which supports otg but isn’t compliant with the standard I guess.

    • Yeah, I noticed that the other day. The cable is compliant, but neither my Nexus 4 or my Nexus 7 seem to work with this cable.

  • Where was this three weeks ago when I needed one!?!

  • Ahh, you’ve made my day! I’ve found these to be stupidly hard to find, even though micro USB is pretty much The One Standard these days.

  • This should work perfectly with the Intel Galileo’s USB host port. Going to buy a couple.

  • Totally got burned by the “Micro-A” I had no idea there was more than one “micro USB” shape. Bought this to use on my Nexus 7 tablet and Galaxy Nexus phone. At least it was not really expensive!

    • I did the same for the Galaxy Nexus but a couple of seconds on the belt sander was all it took to convert this to a microB compatible plug.

  • Well, I didn’t read the description well enough. Micro A… Never seen a device with a Micro A socket. While this might be some kind of standard written on white paper somewhere how is this a practical design? Most people want a OTG cable so they can use their phone, tablet, media player or other device that supports OTG that has a standard Micro B socket that is used for everything. Lucky I already have a spare and maybe i’ll chop the sparkfun one up.

  • It would be worth while to do a production run of this type of cable with a Micro-B end (even if non-standard). I would buy two.

  • This cable will not work with the OTG on the pcDuino which has a Micro B OTG connector like Olimex olinuxino WiFi.

  • Bought this by following a link from the pcDuino pages… then got it and realized the pcDuino uses micro B. Not sure why anyone would link to a non-compliant product. Glad it was only $3.

  • is ID pin shorted to ground?

  • How about an OTG host cable for Mini usb OTG devices? Eg Female A to Mini-A (or was it Mini-B ? I cant figure these out …) well one that fits into Mini-AB and has ID grounded anyways…

USB micro A

Few devices use micro A, those rare times when they do and you want to connect to this is the part, well made and works perfectly. Like the latch, two prongs retaining connector once inserted.

With USB A on the other end, can connect to anything with break out boards or onto A or Micro B now popular.
