Featuring the reliable CH341A USB chip, it supports 24 and 25 series FLASH chips with a fast 2-3 Mbit/min erase speed. The kit includes essential adapters and a SOP8 test clip for safe, pin-accurate connections, making it ideal for repairing, unlocking, and backing up firmware on a wide range of devices including motherboards, routers, and set-top boxes. ## Description BIOS Chip Connection Method and Pin Diagram: Because the BIOS chip on a tablet is not directly plug-and-play like on a desktop PC, when using SOP8 test clips to connect and test the BIOS chip, you must ensure the pin correspondence is correct. Connecting it backward will burn and destroy the chip. For this unit, pin 1 of the BIOS chip is the pin with a small dot. Generally, the test-clip ribbon cable has one wire in a different color, which is the first (pin 1) wire. Make sure this colored wire corresponds to pin 1 of the chip. In this way, you only need to check whether the pin 1 markings match on the test clip and the programmer to ensure everything is correct. Also be sure to pay attention when connecting the test-clip ribbon cable to the adapter board—make sure each pin on the adapter board is inserted into the correct position. BIOS Flashing with Programming Software: After confirming that the chip connection is correct, connect the programmer to the computer. Open the programming software: 1) First step: Detection — check whether the chip information can be read. 2) Second step: Erase — the process is relatively slow, usually takes dozens of seconds. 3) Third step: Blank check — confirm the chip is blank. 4) Fourth step: Load/Select — open and select the .bin file. 5) Fifth step: Program/Write — takes a few minutes. 6) Sixth step: Verify — must pass validation/verification. After completing the above steps, you can solder the power back on and power on the device to check. If the battery/power is low, you may see a few lines of English text—this is also a successful result. After charging for a while, it should boot normally and enter the operating system properly. Package Includes: 1 x CH341A 24 25 Series EEPROM Flash BIOS USB Programmer 1 x 1.8V adapter for iPhone or motherboard 1.8V SPI Flash Memory SOP8 DIP8 1 x SOP8 SOIC8 to DIP8 EZ Programmer Adapter Socket Converter Module 150mil 1 x SOIC8 SOP8 Flash Chip IC Test Clip socket adapter BIOS/24/25/93 Programmer Review: Excellent product - It worked great to backup/restore BIOS on 1.8v winbond 25q64fw for a Lenovo Ideapad 330s-15arr. Laptop would not post, black screen, fans running, LED light on. Used the CH341 to read/backup current corrupt state of BIOS and then using the backup to find and copy important information. Lastly inserted the copied information into clean BIOS before writing back to chip. I had to reposition the clip a few times as it was not seated properly and my application would not detect the chip but once the connection was established it worked fine. Review: Do not listen to other reviews regarding the 3.3v!!! - I'm entirely convinced that people have never actually tested this device while in use then state you should convert it to 3.3v. While flashing it is the correct 3.3v but when it's not it will show what is perceived to be "incorrect" voltages. this is the intended function of the device and works flawlessly. Yes the device the device doesn't come with instructions or software but if you're buying one of these you should already have enough knowledge where this would never be an issue. Great product that does exactly what it needs to do. ## Features - The programmer uses the specially produced CH341A usb chip usb/usb1.1 comms. - This unit is Suitable for amateur programmers of 24 and 25 series FLASH. - Support USB to TTL. - Erasing speed is probably 2-3 Mbit check every minute. - Usage: TV set memory, desktop motherboard, LCD, notebook router, card, DVD, set-top boxes, unlocking software, backup, erasing, burning, checking, repair etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VMPZFWH | | Best Sellers Rank | #8,327 in Computer Internal Components | | Brand | KOOBOOK | | Color | black | | Compatible Devices | Cellular Phones | | Connector Type | USB-A or Mini-B | | Customer Reviews | 4.2 out of 5 stars 180 Reviews | | Finish | Clip | | Finish Type | Clip | | Input Voltage | 1.8 volts | | Manufacturer | KOOBOOK | | Mfr Part Number | KB360 | | Model Number | KB360 | | Number of Items | 1 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | UPC | 682559869002 | | Unit Count | 1 Count | ## Product Details - **Brand:** KOOBOOK - **Color:** black - **Compatible Devices:** Cellular Phones - **Connector Type:** USB-A or Mini-B - **Finish Type:** Clip ## Images ![KOOBOOK EEPROM BIOS USB CH341A Programmer SOIC8 SOP8 Test Clip Adapter Set | SPI Flash 1.8V Adapter+SOP8 SOIC8 to DIP8 Adapter Socket Converter for 24 25 Series Flash - Image 1](https://m.media-amazon.com/images/I/618OQvF-USL.jpg) ## Questions & Answers **Q: I need software driver information** A: Get neoprogrammer and watch a YouTube video on installing and using it. Works well for me. **Q: What software does it use?** A: Neoprogrammer. Works well for me. If your chip is not supported, edit the chiplist.xml file with a text editor with some chip that is similar. Worked well for me using the SOIC8 ZIF socket on two types of EEPROMs, and burned a lotxof chips successfully. **Q: The programmer support windows 10** A: In a word, yes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product *by M***E on August 4, 2025* It worked great to backup/restore BIOS on 1.8v winbond 25q64fw for a Lenovo Ideapad 330s-15arr.
