The RDDRONE-FMUK66 includes a three electrical fuses, which will blow when too much current goes through them to protect the rest of the circuit.

The fuses have changed on recent boards to a automatically resetting type. You should never have to change them. If they do open, simply wait a very brief amount of time for them to reset. However you should determine *WHY* the fuse opened before attempting to use the board.

Determining if a fuse is blown

It is easily determined if a fuse is blown by using a multimeter to measure if the fuse is still conducting. If you are certain that a fuse is blown, you will have to replace it by a similar fuse that can handle 500 mA.

Fuse locations

RDDRONE-FMUK66 has three fuses, two (F1 & F2) for the CAN transceivers, and one (F3) for the USB port.
