Electrical fuses

The RDDRONE-FMUK66 includes three electrical fuses. They will blow when too much current goes through them, to protect the MCU and other components on the PCB.

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.
