From the pull request by zpc0, 22460 and the comment by strrs, it looks like there are at least two versions of hardware for BE805, asian countries gets v1.0 and v1.20, while north america gets v1.0 and v1.60, I got v1.0 from costco a year ago, recent purchase by my friend is v1.60.
From TP-link Malaysian website, it confirms v1.0 is same as v1.60
IMPORTANT: Model and hardware version availability varies by region.
Please refer to your TP-Link regional website to determine product availability.
Vx.0=Vx.6/Vx.8/Vx.9(eg:V1.0=V1.6/V1.8/V1.9)
Vx.x0=Vx.x6/Vx.x8/Vx.x9 (eg:V1.20=V1.26/V1.28/V1.29)
Vx.30=Vx.32/Vx.33 (eg:V3.30=V3.32/V3.33)
There are hardware differences between v1 and v1.2.
The other PR is for the v1 version because v1 uses the AQR113C,
while 1.2 uses the RTL8261BE.
