Oh-oh! I just noticed something between the Empire and the Stubby boards. I went by a number of reviewers who said the boards are the same except the Empire ones are 100 watt boards. Well then how come the Empire board has two screw connectors (where the larger gold plated screws goes) on the fire button side and one on the up/down side? The Stubby board has just the opposite.
Vaperz Cloud pic of the Stubby PCB and the Empire PCB one are identical pics. And here's Bogan's pic of the Stubby PCB.
Identical to the two Vaperz Cloud pics. I see now swapping out Stubby PCB for an Empire PCB isn't going to work. As the connections are in the wrong spots. Now I wonder what the board looks like in the Stubby 21. As the Stubby 21 doesn't have an USB port showing on the outside anyway. May not have an USB on the PCB either just like the Empire PCB.
