Breakout Board for USB microB

Description: This simple board breaks out a micro-B USB connector's VCC, GND, D- and D+ pins to a 0.1" pitch header. If you want to add the increasingly popular micro-B USB to your project, but don't want to put up with soldering the tiny connector, this is the board for you.

Dimensions: 0.8 x 0.45" (20.3 x 11.4mm)

Where is the fifth pin?
Mini-usb connectors have five pins, and the fifth pin is sometimes used for charging purposes. Having it broken out as well would be nice.

  Fake-Name,
  The Pinouts go as follows:
  1) VCC
  2) D-
  3) D+
  4) NC/GND
  5) GND
  Pin 4 is the only difference. If you set it as NC, it’s of Rev. B. It is set to GND, it is of Rev. A.
  I am finishing up fixing SFE’s footprint of the USB Micro. The pins are fully correct, and the symbol is quite confusing.

  hear! hear!
  
  fix that pin and i will buy dozens
  
  Also note that the male one has 5 pins broken out http://www.sparkfun.com/products/10031 spark fun is obviously sexist!

As with the miniB connector breakout, are you going to revise this one to break out the extra fifth pin as well?

Awesome – I’ve been looking for these!
Is there any plan to stock Male USB microB (and even miniB) connectors? I’m building custom USB cables, and the microB connectors seem to be rather hard to find.
Also a miniB female to microB Male adapter would be awesome!

I kinda like this being a 4-pin board. I bought one of these and soldered a USB A socket directly to it for a Micro-USB to Standard-A adapter.
Kinda wish the same 4-pin breakout board style for miniUSB was still in stock.

Wow, this would have worked perfectly had it had all 5 pins. I need both pins 4 and 5 available on this for a large project of mine. Anyone know where a micro USB female port just like this could be found with all 5 pin outs?

Never mind, I just realized this has all 5 pins available, but is just missing the pcb trace for pin 4. I guess I can manufacture my own trace using trace repair wire hopefully.

  Just a heads up for those looking for the 5 pin breakout, it’s available and can be found in the related products section of this page.

    mini != micro
    The related item I see is not the same connector as what’s on this page. I honestly can’t tell you the number of times I’ve confused mini with micro TBH..

      It was there at one point, I think we have since retired the board

Neat put the pad securing the USB is fragile. I ripped the connector off the board this past week with one connecting leg broken off and the pour pad still attached to the other. I’ll switch to USB B mini to get the extra ruggedness.

So why is it that your male USB micro breakout board has the 5th pin connected, but your female one doesn’t? I don’t feel comfortable soldering the connectors myself and this would have been perfect if that 5th pin was connected. =(

Great connector, except the USB jack broke off the board after a few uses. The mounting bars on the side broke away from the solder joints. After re-soldering, the solder pads broke off the board. Lame. I’ll try epoxy next…

What is the mounting hole size/spacing?

  Just taking some quick measurements, I’m measuring a diameter of the holes of 3.3mm with a center to center spacing of 15 mm.

  for dimensions, just look at the eagle files. eagle is free to download and you can get full dimensions from there.

I’m sorry, but this board is ridiculous, and certainly doesn’t deserve to be called breakout, when in fact it is missing to breakout the most important pin (4), the USB_ID. There’s really no other reason to buy such a board, unless that pin is also there. Otherwise you could just use any old USB-to-micro-USB cable, which either shortens ID to GND, or leaves it not connected. This pin is fundamental for being able to construct mobile phone OTG (ID=GND) devices, serial output (ID-R-GND) or designated chargers (D+=D-). Fix it, and we’ll buy thousands!

In fact your USB-mini breakout has this pin, so why not this one? (BOB-09966: http://www.sparkfun.com/products/9966 )
