One of the best explanatory videos on this topic I have ever seen !

The voltage issue of the ch341 affects the 3.3v eeproms only with the 1.8v adapter the voltage is correct for the data pins i used mine on both chips without modification but i consider getting another one and mod it, as for the clip i got no issues reading 3.3v bios chip on board i got the same readings using the clip and the bios adapter but for the 1.8v bios chip i got different readings sometimes the chip was not even detected despite checking with the multimeter the bios pins to make sure they're making contact with the bios legs so yes the clip is to be avoided btw the neoprogrammer feels more trustworthy than the other ch341 tools. Nice demonstration

Good luck with your new company. If you maintain the quality you now deliver, you will have enough customers in no time!

Good video!
keep in mind to measure the ch341a pin 4 and 8 volt first before "fixing" as some dont have 5volt problem depending on pcb factory.

[alhassanibnyussif]

very good explanation thanks a lot sir

[darattaqwa]

Very well explained, good for us beginners

[smithjunkin]

Great video and Good Luck with your business. I hope you do well and to see more videos..😎😎

I had a torture with a clamp for 2 days, could not get it to stick and then i made a lucky contact but reading was inconsistent, it could not erase chip, then could not verify, etc. etc, assorted errors; now i found this video that confirmed that clamp is a pain; some soldering skills and i could take the bios out of motherboard, and use the 200 mil SOP8 adapter on the CH341A programmer; i will post edit after my experiment;

Nice bro, .. very well explanation... Keep it up🤗 more video please😁

Wish you the best with your small business venture and thank you for the informative video.

A simpler 3.3v mod is to cut the 5V trace on the back, and then bridge / jumper the 3.3V and 5V header pins beside the ZIF socket. Then bridge the 3.3v pin on the regulator to capacitor C4, which connects directly to pin 9. No wires or lifted pins required.

I think Sorin in one of his videos used clamps on chip on circuit and broke 1 leg from bios chip

[ohmware]

im using the clip, but not onboard, just to use clip if that sop8 adapter is not avialable... and the software i used is flashrom which i think its more convenient

[box_e.commerce.markeking]

Très génial tutoriel je vais l'essayer 😢 merci pour tt

[stevedebeukelaer]

Hi Mike great video. If you got time can you make tuturial how NVDC Circuit works and how you much aproach it to fix it. I woul realy apreciate it.

Thank you

Great video . The clamp is crap. There is no voltage problem according to Sorin.

[Abdallah.]

Thanks commander really best video on YouTube about programming. However how much air flow and temperature u used ?
Another from my experience I saw that xmc chips has problems with ch341a not always can be success programmed maybe I'm doing something

[pauldanster]

Thanks bro. I think i damaged or corrapted my bios sindbthe PC is nolonger booting. I flashed using clamp.

[ozdemiranil]

I don't know so much about electronics but Sorin made a video about this voltage mod and he said mod is unnecessary. Because that voltage doesn't burn chip with low amps.

Please can you explain and show us in a second video, how you program the Windows key and serial number in a bios file. It would be great!
