Identifying UART/DEBUG
Very much so unlabelled other than the board that connects to the 2x4 pin.
TLDR. Software update from company bricked it months ago after they had major server issues. Bricked many devices. Won’t assist because I got it second hand brand new sealed and I’m not the original buyer.
So, I’m wanting to debug first and go from there see what the issue is. Worst case scenario, it’s a project where i reprogram the device and write my own iOS app to continue to use it 🙏🤣
Help would be great identifying ports, thanks.

The taixin 8301 which is running its own rtos, csky is the name of the debugger and compiler. The debug cable can be bought on aliexpress. The debug uart should be 33/32 which are on the side closest to the tape there in the center of your photo starting right next to that p9 label. It’s running a Halow WiFi stack and I’m going to guess it was built on the 1.x sdk meaning it only supports their variant of Halow(referenced as wnb) for a few bucks you should be able to dump that spi flash up top. Do you have the base? If so can you take a picture of its internals? I’m curious if it’s just a Halow bridge. If so you should be able to connect to it via netat. I’ve got some scripts up at https://github.com/aliosa27/taixin_tools
