Yeah, there must be a small nubbin on the side of each male connector because the female connectors on the board all have a little locking mechanism on the sides.
Initially I thought the connectors were 2.0mm, but after a more careful inspection, the ones on the board above appear to be 2.44mm, so..... 2.5mm or 2.54mm (seems to be a standard)?
