I use the male and female ends on opposite sides depending on which part of an FoC set up they are on, so as not to be confusing. I think you can see them in the video when I remove the blade holder to show the access for the SD card.
Yup. Thats exactly where I saw them.
I've also seen one of these connectors on a MR soundboard before. It held together very strongly. Thank you very much. These will definitely come in handy on my current build.
