@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.
@kimot in theory you might be right, but in practice... it just works. The propability of collisions is extremely low and this is, as far as I know, the only problem you can worry about. After all, it was not my idea to use MySensors with RS485:

@zeblong, you can generate these from the board files, however i'm leaving this one for @Ivan-Z to discuss with you as this is his device and he knows all details regarding this.
