What’s the difference between blink(1) mk3 and blink(1) mk2?

The blink(1) mk3 is visually almost identical to the mk2. It comes in a smaller box but comes with the same 5ft USB extension cable.

Internally, the mk3 uses a new USB chip that is more powerful and allows for firmware upgrades over USB.
