Hey all, I'm wondering if anyone has any idea what this is? (see image) I have a broken HEX16A2 miner that is missing this. Hoping to try and repair it if anyone can assist with finding out what it is. Thanks for your help. Cheers. https://i.imgur.com/Nety0tL.jpg

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.

Thanks for the reply. However let me clarify. The included picture is a small part of the actual board. I'm just trying to figure out what the small part is that is circled in red. The actual board is a HEX16A2 which is an Avalon 2 based system. Cheers

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.

Contrary to what you suggest in your rather stupid and rude reply, I do know what I'm talking about and you quite clearly don't. Haven't you anything better to do with your life, or is your homework too hard for you to do tonight?

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!

I'm not sure of it's function here, but I can say with a 100% certainty that that is what it is. Source: I've taken several microelectronic and embedded systems courses and have soldered these in the past.

Thanks for the info. Would you happen to know what kind of capacitor if I were to try and source a replacement?

Which is EXACTLY what it is, therefore you were WRONG. Or are the 5x HEX16A2 boards I have which are happily mining at 20GH each a figment of my imagination?

Someone who knows post the uf/v value and size 402 502 etc. of that cap please. ie: measure yours if possible.

Use a multimeter and measure the capacitance. If I had access to this specific capacitor, I would. If you can find the circuit design and share it with me, I can find it for you.

You cannot measure the capacitor in-circuit. You really need to unsolder the good cap and measure it with a capacitance meter. The schematics would be a lot easier.

My professor (when I learned how to test capacitance) had a handy meter that would unsolder the capacitor as you tested it. It was one hell of a rig, but still. I tried looking for a schematic and found nothing
