Does anyone happen to know exactly what sort of fuse it is?

I know F1 was put there for a reason, but most switched power supplies have overcurrent protection, so connectiong a very havy load to the USB should only result in the power supply going off as protection. 2015-07-01 17:54 GMT-05:00 John Hawley <[email protected]<mailto:[email protected]>>: As was suggested, the likely cause is a blown F1 (from what we've seen). The fuse can be found on the top of the board near the USB connectors, opposite side from the sd-card cage. It's a little blue thing with an "N" on it. If you have a multimeter, you can check if there's any voltage across the line while the board is on, to see if it's blown (and something I'd recommend before considering an RMA or attempting to repair it yourself). Although it is possible to replace it with another 1.5A - 2A fuse of the same size (it has to be soldered), be aware that doing so will void your manufacturer's warranty. If you've been able to confirm that F1 is in fact blown, I'd recommend going through the RMA process as your first option. - John 'Warthog9' Hawley On 07/01/2015 02:42 PM, Ferchu R wrote: > I had the same issue as Peter (broken F1).
