Garh. Just had a notification from Daniel that our power-filtration capacitors were installed in reversed positions, with the 6.3V cap on the
unregulated side.

We had initially spec'd 16V caps for both positions, but we couldn't source them at the time, so we put a 6.3V part on (what should have been) the regulated side. We're working on an interim solution, but until then, use only a 6V adapter for externally-powered Freeduino SBs!
What surprises me is that the ones I've been using here in the office have been happily eating up 12V for a few months with no visible problem. Mind you, the electrolytic is probably leaking power like crazy, but the fact that it hasn't started to bulge is a testament to the quality of the capacitor!
We'll have notification and replacement information on the website ASAP.
Regards,
Dave (the Freeduino SB guy, who's sucking it up right now!)
