No, it needs a wall wart.

from a different thread:

If I count correctly, that's 379 LEDs which might light at the same
time, especially if you tinker around with MfL. 240 for the endless encoders, 80 for the 5x8 Matrix, etc.

They are quite bright, so even if they are low power versions and take only, let's say, 4 mA (in case of a 1:1 busy cycle), that's already 3 times the capacity of an USB link, for the LEDs alone. Wow!

Lets cross our fingers that they included powersupply is one of those super light weight ones (like the ones with cell phones .. )
