Wow. This is a pretty big deal. There have been third party hubs to pilot Lego Technic motors for a while now, but this HAT is a lot cheaper than any of them (TBF it doesn't work the same either, with no battery, button or physical casing etc.), works with the latest batch of motors, has official blessing, and the RPi is also a lot more extensible and flexible on every aspect. This is a no brainer purchase for anyone trying to do more things with Lego Technic in my opinion.
