CH341A Programmer EEPROM Programmer SOIC8 SOP8 Flash Chip Eeprom Programmer IC BIOS Test Clips 24 25 Series 93C46 Flash BIOS USB Programmer Module (Double Clip+ USB)

easy to use

The clip is garbage and should not be in this, shipping in a bubble envelope leads to damaged pins when they smash thru.

Used this to reprogram a bricked LG subwoofer motherboard. It worked perfectly, for $9.... Immensely satisfied.

Got this for programming eeproms and such. It works fine, but was missing one of the headers shown in the picture (the 2 strip headers) and the packaging could be improved (it was a static bag inside a "bubble wrap envelope") quite a bit.

Review for CH341A Programmer - A DIY EssentialThe CH341A Programmer is a versatile tool that has quickly become a must-have for anyone delving into DIY electronics and chip programming. If you're working with EEPROM, Flash memory, or BIOS components, this programmer could save you time and simplify your projects.Performance:Once you get the hang of it, the CH341A performs admirably. The device supports a wide variety of chips, particularly from the 24, 25, and 93C series, which makes it great for various applications. Programming is relatively straightforward, and I appreciate its reliability in reading and writing data. The double clip feature is especially useful as it allows for a secure connection to SOIC8/SOP8 components, ensuring that you maintain a good connection throughout the programming process.Setup and Usability:There was a learning curve to using the CH341A, but it’s manageable with some patience. Initially, I encountered a few hiccups, but after watching a couple of tutorials and experimenting with different settings, I was able to unlock its full potential. The accompanying software is user-friendly, although it could benefit from a more comprehensive guide for beginners. It is crucial to familiarize yourself with the correct pin configurations to avoid any frustrations during use.Build Quality:The hardware feels decent for the price. It’s not overly rugged, but it should hold up fine for casual hobbyist use. The USB connection is stable, and I appreciate the compact design—which makes it easy to store and transport.Applications:Whether you're trying to recover a corrupted BIOS or experiment with EEPROM programs on microcontrollers, the CH341A is a practical solution. It has proven especially useful for those of us working on vintage hardware or programming flash chips for projects. The ability to quickly test clips with BIOS is a standout feature I've found particularly valuable.Value for Money:At its price point, the CH341A Programmer is hard to beat. It provides great functionality without breaking the bank, making it an excellent addition to any DIY enthusiast's toolkit. Considering the features it offers and the projects it enables, it’s certainly worth every penny.Conclusion:Overall, I can confidently recommend the CH341A EEPROM Programmer to anyone involved in chip programming or DIY electronics. It’s a fantastic tool that, after a bit of trial and error, operates efficiently and effectively. Just be sure to utilize video tutorials and community forums if you run into any snags, as they can greatly assist in your learning process. Whether you're a seasoned veteran or just starting out, this programmer can elevate your projects to the next level.

First thing first, the programmer works well. The app is traditionally minimalist, but it is very easy to use. The device is well priced, considering that the package also includes a clamp and a couple of adapters.The PCB is well made, yet there are a few design shortcomings that make this programmer less useful:- USB connector is soldered onto the very end of the board. The board is considerably large, and the connector can break if you accidentally lean on the board or bend it excessively.- ZIF connector is for DIP chips. Modern devices almost never use DIP chips, serial eeprom uses smaller packages (SOIC, SOP). Reading these smaller chips is not easy with this programmer. A soic connector would have been more useful.- The clamp, from personal experience, is useful in limited cases. Most of the time, other logic on board interferes with programmer's signals and you end up with random read/write errors.

This is a simple, generic CH341A-based programmer board, and should work just fine with any software written for this chip. I used AsProgrammer to successfully read and write a few I2C EEPROMs.At first, I had trouble when using the SMD clip on an in-circuit memory IC, but realized it was because other components on the board were drawing power from the 3.3V rail. Not a fault of the programmer, but something to be aware of. Also, the jumper across pins 1 and 2 changes what mode the chip is in. You'll usually want to leave the jumper in place.Everything arrived completely undamaged, although it was just in an ESD bag.Basically, no worries at all. It does what it's meant to do, and is pretty cheap.

I wasn't ablr to get the ZOF sockrt to jold a chip on it's own. I held it down fot testing lirposes, only to discover that the linux tools that are available support very few bios chips. Out of the 5 motherboard I wanted this for, it did not support the bios chip on any of them. If you are using this in windows, you may have better support, but I prefer to keep my soul, rather that selling it to microsoft. Switch to linux and don't look back. Enjoy.
