    Hi all,
    I'm about to set about repairing a Kindle Fire.
    The micro B USB had broken away from the board and in the process the pins got busted.

    I've a new one on the way, but was wondering if I can get away with just soldering the outside two pins (ground and +5v) so it can be charged using USB only.

    Its not mine so I don't know if there are other features provided by USB but it seems to have WiFi so I'm not sure why it would need USB data pins.

    The pins are minute and I'd rather not try to solder all 5... if it can be avoided.

    Ask the owner if they use the USB port for synching or anything other than charging.

    Ah yeah, I can ask.. but I was more asking if it will work without them connected.
    I assume it will - but wondering if anyone had any experience of that.

    Hmmm, you're right, it might need to see a voltage on the data pins in order to start charging, even if there is no other need for the data lines. You might find someone on a Kindle forum that knows. Maybe take a look at the Minty Boost - I think they've compiled some information about what various devices need to charge properly.
