Are you sure about the gender? For these application IDC connectors are often used, with the male boxed connector on the board, and a female connector to a flat cable:
"IDC" seems to stand for "Insulation Displacement Connector" (which is rather cryptic AFAIC).
If the board has indeed the female connectors then they're for what's called male headers
At the left there's the "straight" version, right the "right-angle" version. These are for PCB mount as well, and with the straight connector your satellite board will be vertical, while with the right angle connector it will be in the development board's plane. The disadvantages should be clear: the way the connectors are placed close to each other on the development board doesn't offer the freedom the flat cables would give you. Unfortunately I haven't seen these headers for flat-cable mount. I would make a small adapter PCB for the header to connect to a flat-cable assembly, like a Micro-Match
which is a one-part connector for directly connecting a flat-cable to a PCB.
