A failed modification of my CH341A Mini Programmer

  • The CH341a Mini Programmer is a super cheap BIOS chip programmer that I've owned for a while now, but I've recently found out there's a problem with it. While the chip socket is powered at the correct 3.3v, the data lines are pulled up to 5v, which is way too hot. Modifications to run the controller chip off of the 3.3v rail are fairly straight forward, and fix the problem completely.
    However, things can sometimes go wrong as you'll see in my attempt.
    It's a relatively cheap components to purchase, and I have a new one on order which I will have to modify when it arrives.
    In the meantime, I have decided to attempt and replace the broken pin as a test of my micro-soldering skills. But that I'll do in another video.
    Shout out to Voltlog and Graham at Adamant IT for their video on this, which I followed to make mine:

    Losing my time. You used half an hour just peeling the wire.

      Never done this type of repair before, but I was not peeling the wire, but trying to attach it. That is when I broke the pin in the connector and was looking how to reconnect it. This was failed repair. But I have since purchased a newer revision of this programmer.

    since started viewing this i knew you were gonna f.. the ch341 because the way you wer working on it
    1st forcing the pin to desolder it instead of (a much more easy) use of desoldering wick
    2nd it would be easier to start the jumper wiring from the 3.3 regulator and taking the wire alla the way to the pin
    3rd it seemed you choose use the thicker copper wire you found instead of a slim one like 0.5mm
    that 2nd and 3rd mistakes caused you to brake the pin, and all mistakes you made throug your video definitely was going to drive you to damage the chip.
    did you make another try? hope so

      Yes, thanks for the comments. This was my first attempt at micro-soldering so it was a new experience for me. I did realise my error, and after a little research I managed to purchase the correct wire and jump it. I did not record it as it took me way longer than expected. Needless to say, my soldering skill have improved since.
