AP28/9120 different about v01, v02, v03

[Maurizio Caloro]

Hello
I have asked myself a few times what the difference is between the 2802-I-E-K9 V01, V02, V03 ?

Also with the 9120AXI-E this would interest me especially with V05, V07?

Unfortunately I have found nothing, I think to this there is certainly also documentation about it, Would be very happy about possible info. Thanks

  - There is little sense to know more because most of it is 'an inside job' ; at one point during the Covid period hardware changes where sometimes introduced to compensate for the lack of components (chips) , that can sometimes lead to the requirement for software upgrades (e.g.)

As @marce1000 mentioned before, normally hardware revisions are confidential work and use to be directed to replace different hardware model components due, or maybe becuase the wireless chipset vendor (Qualcomm, Broadcom) changed something on their chips.
