Looks like a controller board using a PIC single chip microprocessor. It's most certainly not a Bitcoin mining solution of any kind as the PIC 33EP generally runs off it's internal 7Mhz oscillator giving 70 MIPS - way too slow for SHA256 by several orders of magnitude.
Yay! Well done, thanks for posting totally wrong information in a thread. If you don't know what you're looking at, don't post.
Guys like you suck.

Op, the plans for these boards is open source, and should be accessible from Technobit's site. It doesn't look too important, as it's between a USB signal line and ground. Probably a filtering cap or inductor. I'd have thought the miner would run fine without the component.
Thanks for the reply. Had not come across any plans on the site but will look around some more on there. Otherwise I may just try as you suggest running the board without it. I'll still need to reattach a USB header on but that should be doable.
Cheers!
