Just got someone else PCB too… The sticker show my design (HotPlate, which they assigned design number 10220a). The PCB I got (the wrong one) does have that same number on it. So I guess a problem occurred while laying out the batch PCB (which get sent to fab house with all customers design grouped). They put the design number on the wrong design or something like that. So I probably got switched with some mate’s PCB!
I just sent a ticket, will see how it goes.
Meanwhile, did you get the issue resolved on your side?
P.S., if my “switch mate” come to this forum, I got a PCB with the inscription “Koholz Industries 2015” and “rev 1.0” on front silkscreen. My design has “Hotplate Ctrl v1.0 - Eric Hoffman” written on back silkscreen… That it, it even has my name on it and it got switched
