Breakout Board for USB miniB

**Replacement: **BOB-09966. The new version breaks out all 5 pins on the USB connector. This page is for reference only.

We have no idea what USB device you are hooking up to, but if you need to add a miniUSB/USB miniB connector to your breadboard - here it is. Also good for an un-regulated, non-limited 5V supply up to 100mA.

    The PCB looks nice but it only has four terminal pads. The Mini USB connector has five. Probing the one that's missing is the only reason I bought this BOB.
    Doesn't "Break Out Board" mean all pins are broken out?
    Come on SFE, how about a redesign?

    It does not look like they brought out the ID pin. Why? This is my biggest complaint with all your breakout boards, if you are going through all the trouble of building a breakout board why don't you bring out ALL the pins? I see this issue on the MMC/SD breakouts also which seem to be limited to just the SPI signals and not the full 4bit interface ...DUMB!

    Any ideas why you say this will take up to 100ma when the rating for an normal usb socket is 500ma?

    • Applekid / about 15 years ago / 2

      500mA is the limit in USB 2.0. You're not supposed to draw that much without negotiating with the host that you're a high-speed device.
      Of course, everyone does it anyway. :)

      ?!? 2.0 USB flying pigs huh? blue everyone bridges 500mA apple not lolz random.
      So back to trying to address the question... Samtec seems to say that the part itself is good for 1A, so unless SparkFun isn't loving the current-carrying capacity of their tracewidths, I can't figure out where the 100mA comes from either. I was wondering the same thing before I saw your question.
      They might be right, or it could be a typo. I'm having a little difficulty believing that 500mA is problem for any reasonable layout and a good/Samtec part, so I'd just go for it. The worst that's (un)likely to happen is that it'll morph into a $1.95 blown fuse.

        AppleKid is right.
        You can draw up to 500mA, but you have to tell the host you are a usb-compliant device.
        If you dont, the host will limit you to 100ma.
        If you want the full 500mA, strap a usb-uart bridge on to it or something.

        • Natman3400 / about 14 years ago / 1

          Note: Drawing a 500mA current without tell ing the host you are usb-complaint can damage your usb ports. Plus some computers and usb expansion cards do limit you.

  • Does this include the connector or is it just the board?

      Not sure if you found out in the meantime, but it does include the connector soldered onto it.
