My chip was from an HP ProBook 640 G3 and is held in place with a spring retainer mechanism; therefore, programming is done out of circuit. The spring clip of this device _must_ make solid contact, even at the risk of crumpling the pins. Just flatten them out later like I did. If using IMSProg like me, the telltale sign of a bad connection is that erasing only takes a few seconds. With a solid connection, it should take closer to a minute. The programmer works well and is a very inexpensive alternative to raspberry pi and whatnot. If you have a locked BIOS and need to get by the forgotten/unknown password, this is your oyster.

At first the readings I got from the eeprom were blank, I tried repositioning over and over and then with some research I found that I needed to add an additional jumper to the device to match the voltage read/write of the eeprom. If you are having the same problem please look through my photos for jumper placement, this is only for automotive I do not suggest changing jumper settings for any other type of programming. ## Features - The SOP8 clip enables in-circuit programming of without disassembling the chip, making flashing the BIOS simpler and more efficient. - The main purpose of the CH341A Programmer is to back up, erase, program, calibrate and other actions on various software. - The CH341A programmer supports most of the 24/25 series SOP8 chips on the market, but not all of them. Please be sure to check whether your chip model is within the compatible range in the product description before purchasing. - The SOP8 clip support both wide body and narrow body SOP8 chip with 1.27MM Pitch. - We provide detailed PDF tutorials, CH341A software, and drivers, which will be sent to you by email after the order.

I have the same chip and have not been able to detect it or read it. **Q: Can this be used to flash pic/avc/picaxe chips?** A: No, it's for SOP8 EEPROM chip **Q: Is it possible to use this flasher in Command Line Inteface?** A: Yes. **Q: Does this work on macos? what software should i use?** A: This is a windows based program, most of the time a chip cannot be read without removing it. The clip doesn’t fit a standard 8 legged bios chip either. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great for Programming BIOS *by S***T on January 10, 2026* I'm new to BIOS programming, but after understanding it's quirks, this is quite a powerful tool!

Then I found myself wanting to downgrade it. Oops. Fortunately I was able to learn online that I could probably downgrade it with one of these CH341a programmers. I know nothing about these EEPROMs and stuff, but I managed to do it, so I'll share how in case this helps anyone. I created a Ubuntu USB stick and booted another computer with it to run this programmer. The YouTube video I found on using this said the second LED on this programmer will light up when you have a good connection to the chip, but I couldn't get it, and when I'd try to run the Linux 'flashrom' program to read the chip, it said no chip found. Then I read one reviewer that said this chip clip is junk, so I bought a blue Pomona one that was supposed to be better and soldered it to the wires from this one. That one IS a better clip, but in retrospect I believe the one included with this kit would've been adequate for me since the problem turned out to not be the clip. I noticed that when I had the clip on the chip solidly, some LEDs on my motherboard that are usually blue when the computer is on would light up a very dim green, but flashrom still didn't see the chip. If I turned the clip around 180 degrees, I'd get no light from those LED's but flashrom would now say "unknown chip", which really threw me since it made me think it was now seeing the chip and just didn't recognize that model chip. Turned out the orientation the lit those onboard LED's a little was the right one. I couldn't read the writing on top my chip, so I couldn't Google for its model # to find its voltage. I assumed 3.3V, but ended up changing the jumper to 5V also, with no luck either way. Later I learned that the chip was probably 1.8V and Amazon sells voltage converters for use with this programmer for that. But before I bought one of those, I decided I'd try something that was probably stupid. I just turned my PC on with the clip clamped onto the chip, figuring it would supply 1.8V. To my amazement, it worked! For the first time, flashrom was able to identify my chip as a MX25U11283SF, which I then Google'd and found is in fact a 1.8V chip. So I'm not sure how I didn't kill it with the 3.3V and 5V, but I was finally able to program an older version of the BIOS downloaded from ASRock's site, and the computer has been working fine since. By the way, the second LED on the programmer only came on during read/write activity for me. P.S. one of the product photos tells you to make sure to connect to pin 1 on your chip correctly, yet in the photo pin 1 on the cable going into the programmer is backward from how it should be! Look at the diagram on the programmer to find its pin 1. ## Frequently Bought Together - KeeYees SOP8 SOIC8 Test Clip and CH341A USB Programmer Flash for Most of 24 25 Series BIOS Chip with PDF Tutorial - Comidox 1Set USB Logic Analyzer Device Set USB Cable 24MHz 8CH 24MHz 8 Channel UART IIC SPI Debug for Arduino ARM FPGA M100 Hot - IZOKEE CP2102 Module USB to TTL 5PIN Serial Converter Adapter Module Downloader for UART STC 3.3V and 5V with Jumper Wires --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/138516502-sop8-soic8-test-clip-and-ch341a-usb-programmer-flash-most](https://www.desertcart.pl/products/138516502-sop8-soic8-test-clip-and-ch341a-usb-programmer-flash-most) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-22*
