I asked this same question as the board he (OP) has is a //3 and not a //1 (last characters of the firmware version) and it confused me as well.

Here is Terry's response.

"//1 and //3 are both the same old PWG V1 board with a minor difference, //6 is the PWG V2 board that we've been using on all N55 PWG systems since around 2018"
