Guys, addressing my ignorance, what are some uses/applications for the “common ground” option of these pcbs? Why would I need to do this? Thx Ted

If you do anything with TMCC or early Legacy, many of the signals and lights are returned to frame ground. So, most of the stuff I build either uses half-wave power or has an option to jumper for half-wave power so I can use it in those situations.
