Eeprom BIOS USB Programming Device Kit CH341A + SOIC8 Clip + 1.8V Adapter + SOIC8 Adapter For 24 25 Series Eprom Flash
60.00 AED
CH341A USB programmer kit listing with SOIC-8 clip, adapter board and 1.8V adapter for supported 24-series EEPROM and 25-series flash applications. Confirm chip voltage, pinout, package dimensions and software compatibility before purchase.
The CH341A EEPROM BIOS USB Programmer Kit is a versatile, low-cost tool primarily used for reading, backing up, and rewriting firmware on 24-series EEPROM and 25-series SPI Flash memory chips. It is widely used for BIOS recovery on motherboards, repairing bricked routers, and modifying firmware in various consumer electronics.
Kit Components & Functions
CH341A Programmer Module: The core USB interface that communicates with the chip via SPI or I2C protocols. It typically features a ZIF (Zero Insertion Force) socket for direct chip placement.
SOIC8 (SOP8) Test Clip: Allows for in-circuit programming, meaning you can clip onto a chip while it is still soldered to the motherboard.
1.8V Adapter: Crucial for low-voltage chips (e.g., modern laptop BIOS chips). Standard CH341A programmers output 3.3V or 5V; using them on a 1.8V chip without this adapter can permanently damage the chip.
SOIC8 to DIP8 Adapter: A small PCB used to mount SMD (Surface Mount Device) chips for more stable connection when they are desoldered and placed directly into the programmer’s ZIF socket.
Common Use Cases
BIOS Repair: Flashing a working BIOS image to a motherboard that failed an update or became corrupted.
Firmware Modification: Unlocking hidden BIOS features, such as “Turbo Boost” unlocks on certain motherboards.
Data Backup: Reading and saving the original firmware (“dumping”) before making any hardware or software modifications.
Device Unbricking: Restoring functionality to routers, TVs, and set-top boxes after failed firmware installs.

Essential Usage Tips
Pin 1 Alignment: Always align Pin 1 of the chip (marked by a dot or notch) with the red wire on the clip and the corresponding mark on the programmer.
Software: Common compatible software includes AsProgrammer, NeoProgrammer, or the command-line tool flashrom for Linux.
Power Down: Never attempt to program a chip while the target device (motherboard/router) is powered on.
Verification: Always perform a “Verify” operation after writing to ensure the data was written correctly and matches the source file.
