For which version of kit is this?
Thank you!

SCK 2.1 :rocket:

I try to follow the instructions at but somehow this doesn’t work for me. First I can’t get a red light so I can’t get it into Set Up Mode. Second (I already had the token written down) I can’t get a steady green light. A flashy one I have, but my Macbook won’t see the SCK. Can you help me update the firmware? Thanks!
