So I have got a Eleven (Arduino Uno copy) micro controller, and during the programming it, i got excited to test the new algorithm, but forgot to pull out the usb cord. So the USB PORT on the arduino controller ripped right off...
So is there anyway to fix it? Can i solder the joints together? or its unfixable??
Here are the photos
Hi
Looking at one of my Elevens here it appears to be just connected by 4 solder pads for the mechanical connection to the board, and 5 fine electrical connections at the rear. That bit could be tricky, but re-soldered carefully under magnification I think you'll get your Eleven back.
All the best ! Geoff
thanks for the input Geoff!
Also I should mention, I am able to power the arduino/eleven by holding the serial port in place while connected to the laptop

I don't know how safe it would be, but if you soldered the big pads back on you may have a working board that might last until the finer contacts can be re-soldered.
Yes, that will be re-solderable.
First carefully clean off any old excess solder with solder braid.
Then add lots of flux.
Tin one pad, and hold the connector in situ. Re-melt that tinned pad and let the solder wick up on to the pin.
Carefully add more solder to the other pins and supports. If you struggle, add more flux.
Ideally you want a temperature controlled iron so you don't overheat the pads and lift them from the board.
It takes a steady hand, but it's not as difficult as you'd at first think. I regularly solder SOIC chips, and even 0.4mm pitch TQFP chips by hand. (the latter is "fun" to do).

You've still got a perfectly good 2.1mm socket there. I think that'd be a far better option for powering it. If you've only got 5V to power it, then connect that source to the Vin & GND pins.
Cheers ! Geoff
"If you've only got 5V to power it, then connect that source to the Vin & GND pins."
No, connect to the 5V & Gnd pins on the header. Using Vin will drop voltage as it needlessly goes thru the regulator.
It's perfectly possible to re-solder the connector. No pads has been ripped off - you are very lucky. Clean off the old solder on the connector and on the pads with a good solder wick. Apply lots of flux and re-solder the connector, simple.
