Any hardware engineers here?
Just bought USB server (like, a box) and looks like it's built on EST E3868M4-B but I can't find any datasheet for it. Is there any information available about its pinout, architecture and is it possible to reflash it with something different? Any information is welcome
Boosts are also welcome, and feel free to kick my ass bc I'm asking stupid questions

There's debug interface on bottom left, I wonder if it's UART or something else. Big chip on the left is already mentioned E3868M4-B, another one on the right is RTL8211CL and below both of them something that looks like flash memory (F25L004A, looked it up, it is 4Mbit flash). A couple of voltage regulators on the top and that's it
