“They are ev3/NXT compatible connectors but you will have to google for what each wire is online and my biggest problem is they don't fit onto a breadboard! I had to solder wires on witch is kinda difficult as there very small ik some other connectors witch are like this but have a mini breadboard that works perfectly with breadboard if that's what you are looking for I would recommend that for you.
The product itself is perfectly fine tho just remember it won't easily connect to a breadboard unless you solder on wired like me.”
