This is a set of stackable headers so you can make your own shield for the Mojo. They are high quality gold plated headers. Gold plating is important when you have this many pins because it makes it a lot easier to connect and remove your shield (as well as giving a better connection).
The Mojo uses a standard 0.1 inch pinout so with these headers you can turn a generic protoboard into a custom shield.
These are the same headers we use for all our stackable shields. And the pins are 0.394 inches long.
