Do you need this FPC network adapter board?
This board is for internal testing and is not yet officially for sale. Note: We have only tested its network transmission; no further reliability testing has been conducted.
Let me know how many people need it.
IMO most people want a PoE out - i dont understand why a “pro” board like the R4 pro has none.
Poe-out would need a much more powerful supply and bigger/better regulators. Imho you better using external poe adapters if you need it
the idea behind poe out is to not require a extra poe adapter 
that it requires a stronger power supply should be clear, as it powers the other device too.
I believe POE is 48 volt at 1 Amp. So it would need a very strong power supply.
dont believe.
poe is 12.95w, poe+ is 25.5w per end-device
Just back to topic. I thought the fpc adapter will be sold too as it was listed in the spec,so i got one for adding the software support (in my repo). Will change to overlay to have it visible only when needed.
Imho cable is currently a bit short and case does not have abilities for mouting the subboard.
Yes, BPI wants to see how many people need this adapter board so they can figure out how to arrange it.
yes, I need 
but ofc for reasonable price, frank thanks for new overlay to handle this lan port.
what are some use cases for this? I struggle to imagine any besides the obvious of getting another port.
Imho it is just another port from internal switch,so supported without the current mxl firmware/driver hassle.should be usable in uboot too,but not tested.
Because it’s a network port connected via an FPC cable, the length of which can be customized. Therefore, this network port can be placed anywhere for customer use.
Yes， need it to support one more ethernet port.
When will it go on sale
Which image/code do you use? I guess the port is not enabled…only in my dedicated kernel i have added an overlay for the fpc which must be loaded
As the level of customer demand is currently unknown, we are producing a small quantity of these boards; sales channels should become available before long. For specific pricing and availability, please consult BPI.
mmortalWrt 25.12.2self-compiled firmware
Do you need any other patches?
It depends on which dts immortalwrt is using for r4pro
The upstream dts has the internal ports disabled except lan5 so you have to enable the fpc port and set leds with overlay.
I thought i had it ported to openwrt too,but seems not.
