Chosen Solution

Original Jambox has a small board that includes the on/off, the mini jack sound output, and the micro-usb charging port. My board has been destroyed (I inadvertently overheated with a soldering iron, trying to reattach the charging port.) I need either a non-working Jambox that has an intact board, or the board itself. Any help out there?

Your best option is to pick up a faulty one from somewhere like eBay and gut the board. Then sell the remaining for spares.
