SOIC8/SOP8 Test Clip + CH341A USB EEPROM Programmer — 93CXX / 24CXX / 25CXX
This kit combines a SOIC8/SOP8 in-circuit test clip with a CH341A USB programmer module for reading and writing 93CXX, 24CXX, and 25CXX series EEPROMs and SPI NOR Flash chips directly on the PCB — no desoldering required. Essential for BIOS recovery, ECU programming, router firmware flashing, and embedded system repair.

Why Choose This Kit?
- In-Circuit Programming — SOIC8 clip reads/writes chips without desoldering from PCB
- CH341A Reliability — Proven USB-to-SPI/I2C bridge IC used in millions of programmers worldwide
- 3.3V/5V Selectable — Protects 3.3V-only chips (most modern SPI flash) from 5V damage
- Free Software — AsProgrammer and NeoProgrammer are free, actively maintained
- Complete Kit — Clip + programmer + cable; ready to use immediately
Typical Applications
- BIOS chip recovery and firmware backup (laptop, desktop motherboard)
- Router and switch firmware extraction and flashing
- ECU EEPROM reading for automotive diagnostics
- Smart TV and set-top box EEPROM repair
- SPI NOR Flash programming for embedded Linux devices
- 93C46 EEPROM programming for odometer and immobilizer repair
FAQ
Q: Can this programmer read W25Q128 (128Mbit) SPI flash?
A: Yes — CH341A supports W25Q128 and other large SPI NOR flash chips via AsProgrammer software.
Q: Do I need to power off the target board when using the clip?
A: Yes — power off the target board and let CH341A supply 3.3V to the chip via the clip. Leaving target power on may cause conflicts.
