Just want to inform all, that R4 and S9 control boards are compatible and accepts opposite firmware.

Tested on R4 with 9 hash board connectors (3 populated) -> moved to S9 and flashed latest fw for S9
S9 controller board with 16 hash board connectors (4 populated) -> moved to double R4 (all four hash boards with one S9 controller in R4 case). Left original S9 firmware.

Both S9 and R4 controllers are compatible dimensions and can be swapped. R4 ribbon cables needs to be removed from tray (they are a bit shorter, but usable).
S9 firmware requires TWO FANs or it will stop hashing.
