    Just exploring about this tp-link XN020-G3v router. I’m mostly interested in connecting to the UART, won’t be tinkering with electronics of it, but out of curiosity I tried to search what these chips are. and I couldn’t find much about the big chip. Can anyone describe the 4 main chips on it ? Best would be datasheet, but whatever information you can provide.\n
    \n
    I suspect\n
    \n
    1. bigger one(ECONET EN7526FCU) is CPU/SOC, (couldn’t find datasheet/specs). Can anyone provide details ?\n
    2. MT7592N is definitely network IC(found datasheet)\n
    3. Le9641PQC is network IC. required for VoIP. (found datasheet)\n
    4. AJ194 (backside) is flash ? How to tinker with it ?\n
