I'm trying to identify the board and chip of a Chinese made wifi6 extender. It's an AX3000 and seems to be a white-label device since it comes in many names - Fenvi, Kebidumei, and some others.
The device surprisingly works well, but the software is terrible and pretty much useless. I'd like to have Openwrt running on it instead.
I opened up the device but couldn't find anything to identify this by. So I don't know if there's an openwrt image I could use.
Looking for help identifying it
PCB is green, you know. Kind of we dont see through heatsinks either.
I could remove the heat sinks if that will help. I hoped the shape and brand will trigger some ideas.
It's a WD530A v2 PCB... but that doesn't help with the software side of things much.
You should just be able to rotate the heatsinks from side to side a little bit at a time to get them free (assuming it's just an adhesive and not a cement holding them down).
One of them is likely the main routing chip, the other is likely a wifi chip. They're the important bits.
Connect to the serial port shown on the device and log the output from boot up. This should indicate the boot loader (hopefully U-Boot) and may tell us what SoC is used.
Managed to get the heat sinks off, these are the chips:
This thing doesn't come with a USB connection for serial, so I ordered an adapter and will report the boot loader info as soon as I have it.
pretty much no device do, you need an USB TTL.
MT7981b, you've got a few options to look through to see what might be the closest match...
You'll want to wait until you get the TTL adapter to really check on some of the more intricate details.
The rule for the serial is you start by only hooking up GND and RX.. once you've confirmed you've got your RX right, then hook up TX. NEVER VCC/+VE
looks very similar to the Cudy RE3000
I saw another post claiming to have used the Cudy RE3000 image, but the post got locked before the author said they were successful or not.
The 4-pin serial port is clearly marked with 3V, R, T and G.
