i guessed he meant via gpio-lib/sysfs setting this gpio to low…at hardware layer imho it is hard to access (especially when board is running) without shorting anything else (once i know the pads to do this)
Well, it is not that hard if you have the right tools. It is a development board for a reason.
I was hoping that this is a fix to mend the horrible signal to noise ratio degradation when SFP is not populated, but it seems the core PCB design remains same. Yes I am ranting here, because you could simply look at AsiaRF board design and take some notes and learn. High speed signal routing, ESD protection measures and heat management, just copy, paste, but oh well…
BTW I just retired my BPI-R4 due to various device quirks. I still use BPI-R3 as it holds pretty well, besides the bug you cannot plug 100Gb device to the switch part, it still stalls making it dog slow.
When it will be available in market ? 
Like BE19000 almost 2 years or 3 from announcement date 
Nice Update!!! The BPI-R4 V1.3 looks like a solid refinement with better serial port protection, improved SIM/eSIM support, and some useful hardware optimizations. Good to see small but meaningful upgrades. Looking forward to its availability.
Hello, how do I purchase one of these new boards? Ideally as a kit.
As far as I know, BPI-R4 V1.3 is expected to be released in July.
Stay tuned.
I looked at the BPI-R4 Pro schematic:
It looks like the new v1.3 revision of the R4, but I’m not sure …
→ Have you had any problems with the Pro?
I thought the problem on the R4 v1.1 had been “solved”?:
→ [BPI-R4] Zyxel PMG3000-D20B SFP module not detected - #58 by simon
→ Sadly, Simon did not answer you …
7 July its a great day and the weather is hot , so can we see hot sales 
with V1.3
