Re: [Review] Avalon 6 Miner - Winter Mining - Notlist3d - Also FAQ and Help

Hi

  I have some, not working  Avalon 6 blades , with expired warranties, anyone knows if Avalon in China or USA offers service repairs for these blades.

Thanks


I would guess they would sell you another blade, but don't know on repairs.  Have not heard of repairs, just paying for new blades.   But contact BlockC and see what they say - http://www.blockc.co/#contact

Out of curiosity did you over volt them?  Or what caused the problems.

Blade never was over volt, physically they don't have any burn or lines parts, BlockC doesn't carry  after-warranties, any help on repair tips.
Thanks

Re: Antminer S5 Mosfet 5pin U3...U50 Need Part Number

The main part you are likely to need when repairing is the Hash ASIC BM1384, (U4 - U47). These would only be available from Bitmain, however I suspect they are not selling them, so you will need to remove devices from a failed board to repair others.

Rich


Rich I think that P/N is : SN74LVC1G07 Single Buffer/Driver With Open-Drain Output

Yes sorry my mistake, U6, U9, U12 ..... U39, U42, U45 are as you say SN74LVC1G07 The rest of the chips in the Range U4 - U47 are the BM1384

Rich


You are 100% about chips numbers ...
And thanks for confirm the SN74LVC1G07

Also step up U101 was founded by other user ( looks 100% exact part), take a look and let me know, here the link

Are you really asking for the part numbers for most, but not all, of the Integrated Circuits on an S5 hash board? If you have a board you can read them off? Give us a bit of background, why you want this information?

Rich


Rich
These part Number has a B2B number but do not belong to any commercial or technical part, that's why asking for help.
Basically need it for repair my bad boards

Thanks

I'd place my bids on TPS61170 as compatible.
I didn't check the pinout against what is on the S5 board, but it's the only one I've found in 6 pins package with specifications that would match the part on board regarding Vin and Vout.
The device marking is supposed to be BZS, but maybe the one on the S5 board is simply a clone from another manufacturer.

http://www.ti.com/lit/ds/symlink/tps61170.pdf

Am away from Home, but looking at a picture of an S5 Hash Board the Pinout ties up with the TPS61170, so I think a good call.

Rich

After checking the S5 board it looks 90% that TPS61170 belong to U101 ( step up voltage) for S5 hashboard

Re: Need S5 and S4 and S3 Hashboards Schematics

Antminer S1 schematics are available.

https://github.com/AntMiner/AntGen1/tree/master/PCB

They are a very good guide to the other Miners in particular the S3 if you combine them with the ASIC Datasheets.

It looks like pretty simple step-down circuit.What are you supposed to get out of it? I think you can use that other U2 circuit instead of U1 circuit. U2 seems to be pin-compatible with eg MP1484.



I check MP1484 and is not pin compatible any other sugestion, any sugestion
