Yep this should be an easy fix. J15, when shorted sends uninhibited current to ground through the NPN transistor BC817. This transistor has a max collector current of 500ma. Chances are this was exceeded and burnt out the transistor. I believe it is the SOT323 package too. Can anyone confirm?
Thanks

I'm pretty sure there's only one version of the schematic for the UM2 at this point. Any changes to the board have been parts only I suspect - the layout likely hasn't changed.
