    You're a Bad Ass! I think you provided everyone a solid foundation with knowledge to build skills.

    Great job! Kindly do a video on how to edit the firmware and write it back to the chip 🙏

    What microscope are you using?

      At the time of recording this video, I was using Andonstar, but see my latest video on Tomlov, I switched to using Tomlov since

    Note: If a 8 pin chip is next to a bigass inductor, it's possibly a power supply IC 😉

    Hello, really nice video !
    How long does it take to read the flash on the TP Link ?

    I guess those resistors on TX and RX lines, working as voltage divider. In this case you can use 5 voltage logic.

    What microscope are you using to look at that? My eyes are not as good as they use to be.

    But can you extract that chip data using the UART port?

    • @TechnicallyUnsure

      Unfortunately no, you can not. UART is just for communicating with the OS, reading and writing to the "terminal".

    Good job
    I bought a T48 a while ago. For handling with controllers Atmega16, v32, 644
    T48 did its job with atmega644 microcontroller
    But with the Atmega16, 32 controller it copy random and mismatched data to the data on mcu memory
    If you match the data in the beffer with the data in the controller, it gives more than 900 errors
    I wrote to the manufacturer China... No respond.
    I wrote agine in Chinese , they did not respond and did not provide any support
    I never recommend programmed t48

    Hmm n300. Wonder what website has a write up on exactly what you did…

    The mystery board looks like a HooToo Tripmate Nano Travel Router. I have one the same.

      Oh. My. God. Thank you man! I really didn't know what it was and I just googled it and YES! I had that, you are 100% absolutely correct. Thanks for letting me know

    so im guessing you watched a video that suggested that you make a video that has a bunch of pointless hand movements. to help explain stuff. thanks, great job
