Is it possible to convert an old style SF800 to work with the new Kegboard Pro Mini?
If by “old” you mean a bare 3-conductor meter, then yes. You just need to crimp or solder an RJ-45 connection, following the KegJack pinout.
FLOW1 is available for a second flow meter
Does this mean I could wire up two flow meters to an RJ-45 and have it recognize the second meter?
Yes, it does!
Woot! Just ordered two of the Minis… Now I have one for an xmas present!
And I just realized I can plug a keg coaster into it.
Precisely
