WWZMDIB CH341A EEPROM BIOS Programmer SPI I2C + SOIC8 SOP8 Clip + SOP8 SOP16 Conversion Plate for 24 25 Series Flash

I used this WWZMDIB CH341A BIOS Programmer to recover and flash the BIOS on my ASRock BC-250, and it worked like a charm. If you’ve ever bricked a motherboard or need to update firmware directly on a chip, this is the tool you want in your kit. The kit comes complete with the CH341A programmer, a solid SOIC8 clip, and SOP8/SOP16 adapter boards — everything you need for in-circuit programming. No soldering required — just clip it on the chip and go. The SOIC8 clip held firm and made clean contact with the BIOS chip on the first try. It supports a wide range of EEPROMs (24, 25, 93 series), and it was compatible with the chip on my ASRock board with no issue. I used open-source tools with it, and the backup, erase, and write process was smooth and reliable. If you’re into PC repair, BIOS modding, or just want a way to unbrick a bad flash, this little device is powerful, affordable, and easy to use. Absolutely worth it for the peace of mind alone.

Never thought I’d need this, but it came through when flashing BIOS. Setup was straightforward and the tech worked exactly as expected. Reliable and worth having in your kit. I can't say much about durability aside from it's not a rugged piece it's delicate the way ram would be. Take care of your things.

This thing right here.... too much power for a couple buck lol. I was not sure this will work to be honest. I had a 16 pin BIOS chip that needed flashing I paired this with a 300mil SOIC 16 to SOIC8 adapter and got the job done. Now I've been using it to make back ups off all the BIOS chips I work with (old and new) and I haven't have a single issue. I did notice that has a wek point by where the USB-A connector meet the CH341A board, those welding spots could becomenundone by the weight of the boar + connectors, I will suggest to handle the devuce with care and if possible place something underneath it to keepnit stright while using it to avoid bending and possibly breaking those welds.

I am mostly using this to read into flash chips for reverse engineering purposes, and it does its job as intended. Nothing less, nothing more. Works best with my Linux machine though, my Mac was hit and miss with this chip. I cant speak for its success with windows.

They are hard to clip on to bios chip I must be missing the trick

Decent reader. Less than decent clip.

4/5 based on price to quality comparison. Would have liked some type of instructions, or at least a link to a site with a diagram for different chips. I need 3.3 V to flash my bios chip, but wasn't able to find documentation on how to set it upp. Although I don't think that is specific to this brand. It seems to be difficult to find instructions on using these programmers in general. Especially for a 3.3 V chip without having to do DIY modifications. I would still recommend it if you know that it will work for what you're trying to do. Its worth the price and I will be keeping the one I have even though I couldn't use it this time. It's going in my computer tool bag.

This doesn't seem to work at all. AsProgrammer cannot find it. It initially comes up as USB-UART LPT by default. Maybe that's normal. But, the appropriate driver for the CH341 doesn't seem to work with it and I have to manually select it as the driver. I also noticed that the chip on this is a CH341B, not CH341A, so that might have something to do with it. Though it's sold as a CH341A, so that seems scammy. No documentation or user guide or software included. Maybe someone out there has a better idea of how this is supposed to work, but from what I've found, it should be pretty quick to setup. So, I'm leaning toward scam.

Tenía 2 laptops con problema de bios una Dell y una Hp. Con el pude reprogramar fácilmente y sin problema, no tuve que desoldar la bios ni nada. El programa lo encuentran en línea y los archivos hay un canal en telegram que tiene de todas las marcas.

Muy buen producto, me sirvió para la recuperación del bios
