I do not know if there is a difference between them or even if they perform the same tasks, one of them works better than the other, or is the only difference in the factory for the board?
Please help if there are any anyone who has tried using any of them before or anyone has information on the subject
And thanks a lot in advance for the help.

They look the same, never even seem them before, quite interesting. Without any documentation it will be impossible to say anything sensible about how they are put together and how the firmware, that is on there already works, or how hard it will be to upload your own.
