How to get Exoskeleton Mark II using console?

The equipment called exoskeleton-mark-ii so you can just type
/c game.player.insert({name="exoskeleton-mark-ii", count=5})
To see the names of all items in mod you can just open mod folder, there will be 'prototypes' folder inside. In there you will see .lua files, open them with text editor - there will be the names of needed items in "name" section. Works with all mods!
