Need some help on some info for old S3s

[Markitzero123]

I got two used S3s to play around with bigger SHA256 asics the previous owner didn't treat these things right the fans were in wrong orientation once I tested them unit 1 a somewhat good control board 1 good hash board 1 bad hash board, Unit 2 1 Bad controller and 2 good Hash boards. So I tried to make 1 good unit out of 2 half to non working units. I got it working but after a few boot the internal USB to UART section went belly up not seeing the Hash boards or Fan signals tried it on all 3 working hash boards. I was reading is post from back in 2015 on here were a adapter for the S3 hash board was worked on sadly I can't find a picture of the board or even the schematic, and the site alot of the picture were stored on didn't make it to the wayback machine

I am referencing this thread - https://bitcointalk.org/index.php?topic=671128.880

I am looking for the circuit diagram or schematic or even a good picture if it is a single layer board. If there is another way let me know.

I mange to find the pinouts I am thinking for the S3 Hash board from the thread, Can you use the old USB Block Erupters to slave out its USB to UART interface if that is what its header is for, I have 3 of those.

Right now the 1 and a half  S3s are paper weights. I know for bitcoin they may not be profitable but there is other SHA256 Altcoins and i am doing this as a hobby

What you could do is hook the boards via UART -> USB and try this way.

There is also this github project that used similar way.

Was created for the S1 but I am sure there is possibility of this working on the S3 boards too.

Hope this helps.

Both control boards will boot the custom OpenWRT and can load the Web interface but 1 the fans go full blast and the other not but doesn't see Hash boards or the RPMs on the Fans but the fans turn off waiting for the turn on command I am guessing.

The first link I am guessing forces the thing to do a factory image reset
The second link being mainly javascript which I guess replaces the web panel
