Difference - 2GIG-CP21-345E and 2GIG-CNTRL21-345?

Are these the same 2 panels or are there differences between them? I’ve seen different sellers advertising them with these various 2 model numbers.

2GIG-CNTRL2-345 is a previous hardware version of the same panel. 2GIG-CP21-345E is the proper model number for new panels. (Looks like that was missed in the product description, thanks!)
