Title: Gridseed / burnt down Post by: steff119 on April 22, 2014, 05:20:33 PM Can anyone tell me, what the marked parts (1-5) are?
I have two Gridseed miners (5 chip version, 350 KH/s), where this parts are burnt down. http://i62.tinypic.com/29d74fd.jpg Title: Re: Gridseed / burnt down Post by: jd_grinder on April 24, 2014, 11:10:42 AM the component marked FB is a ferrite bead(5 on your marking). the rest are capacitors.

If FB denotes ferrite beads, then 1 and 2 are ferrite beads. 3, 4, and 5 are caps.
