I saw this module for the first time, but it doesn't look much different from the original S9 hash board, except that the positions of several triodes have changed.
It can be seen that this is a repaired hash board, because this area is the power supply route of the S9 hash board. Once this area fails, the hash board will not work.

I don't see any difference between the old s9 hashboard compared to your hashboard.
You might be just purchased a used miner with a recon(repaired) hashboard.
Those parts are the most common issue like a shorted so possible that part in your hashboard disconnects all connections and replaces a new small board to bypass power or to fix the shorted part.

Hi All
Just purchased an S9 cheap and openend it up to check/clean and found they have added PCB boards?
Never seen these before anywhere on other S9 boards.
Anyone know what they are and why they are there?
Thanks
