So, you did end up flipping it? I agree that it's not something that is really ideal to do, but knockoffs are like that sometimes.

 

Banggood is just a reseller not a manufacturer, this is a well known issue with some cheap Chinese boards the keyway is on the wrong side of the connector. Usually they do not last long in the market before they fix the issue, Chinese want to sell thousands and bad news travels fast in the Internet age. Not helpful if you actually have a board with swapped keyways, but glad you figured that out and got it solved. Otherwise, please note that Amazon and the likes sell the same stuff from the same Chinese factories, so there is no guarantee you will get a perfect board from them either.

 

Not all of them
Mine worked fine, but it is BangGood... so everyone's mileage may vary on any item.

Still, very nice job of catching that and if someone else has this issue they will not be lost.
