There are 2 versions of the BS-U25WF:
- with a ralink rt5350F and one anteena, see this russian blog: http://qpcb.buhost.ru/?page_id=87 there is a picture of rx and tx
- with a mt7620n soc, this ona has 2 antennas (that is the one I have)
Both are with a baseboard and a pluggable mainboard with the soc.
I found the tx and rx also on mine. So I had chance to unbrick it. and it runs openwrt just fine, altough the ethernet port doesn't work, altough when booting The lights of the ethernet port flashes and you get a failsafe message through it. Once it is booted it doesn't do anything anymore. Will probably a configuration issue.
I don't get it working as wireless repeater also, it works as AP and as Client, but not both on the same time. Probably also something in the configuration.
I didin't have time to look into it further. From the moment I find out how you can add pictures to this forum, I will upload some pictures of the serial location.
Further I can tell you these specs:
- soc: mt7620n
- Wireless: rt5390
- ram: 64Mb
- Flash: 16Mb
- 2 antennas

Picture of SOC - I don't know I you can see, but there is written: MEDIATEK MT7620N
