It appears there are 2 versions of the PCB out there. I know there was some discussion about modifications to the initial PCB design IF another batch was ordered. I guess they were ordered?

I see the 7805 voltage regulator (circled red) faces oppositely. The left photo looks to be PCB Rev 1.0 (circled yellow); the right photo Rev 1.1?

If you're having a problem with the voltage regulator, can you confirm the 7805 orientation matches the version.
