Mistery box
galileo:
Does anyone recognize this board? It is claimed to be an SDR from a drone but it looks like a development
board for a router to me.
What I deduced so far: looks like it has 2 receivers with 4 ports each an Ethernet port, lots of unused SMA ports.
TNC like connections give WIFI vibes.
Any ideas?

Would have to be some very weird router - the circular connector hints at serious use. The way that the capacitors and connectors are held in place is something that you don't do for the fun of it, but rather when you really need it due to vibrations. It could be something drone-ish hacked together from borderline off the shelf parts?
More photos would be more useful, such as what is the chip in the middle? FPGA or ASIC?
AndyBeez:
From the solder mask color and component density, the top board looks similar to a Cisco made PoE business access point. Take a look under the top board for any identifying brand names or serial numbers.
What's underneath? I'm guessing, but those boards might be RF amplifiers.
The whole unit looks a prototype though, so don't expect a user manual anywhere. Maybe it is the base station for a drone system? Or it fell off a phone mast.

That picture is from the New York Times article which reported that Iranian weapons are supposedly made with Western parts, right? Why don't you say so?

Behind a paywall unfortunately.
AndyBeez:
Well then... as a possible drone launch control system, the Russian war criminals attacking the civilian's of Ukraine with Iranian drones, might just want their Roubles Dollars Bitcoin payments back for parts they could have otherwise sourced from a dumpster in Minsk.
