That's how mine are still set up.
And for what it's worth here are the prints of the two different styles in place.
My #2 module I have battery consumption issues with but I think that is because it got submerged in water once in the first location it was sitting (need to replace that 
). My #3 has been in a freezing-to-hotter-than-hell steel mailbox for a couple years and is only just now giving me some battery consumption concerns (it is also the only one NOT hacked per my prior post). #1 has been in a dusty freezing-to-hot environment for a couple of years and been rock solid only sipping battery.
I had forgotten these had some differences, interesting to me that #1 has never given me concern.
#1 (as pictured in prior post above discussing freezer use)
