CH341A USB Universal Flash Programmer Kit
A versatile and cost-effective solution for reading, writing, erasing, and repairing firmware on 24/25-series SPI Flash (EEPROM) chips. Designed for hobbyists, repair technicians, and electronics enthusiasts, this kit supports in-circuit programming via a non-destructive test clip, eliminating the need for desoldering. Powered by the CH341A USB interface chip, it offers reliable compatibility with consumer electronics firmware repair tasks, including BIOS/UEFI recovery, router modding, and TV/set-top box repairs.
Supported Chips:
24-series EEPROM: 24Cxx (e.g., 24C02, 24C64)
25-series SPI Flash: W25Qxx, MX25Lxx, SST25VFxxx, and other 3.3V/1.8V chips.
Limited support for Atmel microcontrollers (e.g., ATmega8/AT89S52) via third-party software.
Interface: USB 1.1 (CH341A chipset) with plug-and-play driver support (Windows XP/7/10/11, Linux).
Voltage Support:
3.3V (default) with built-in voltage regulator.
1.8V adapter included for low-voltage chips.
Speed:
Erase/Verify: ~2–3 Mbps (e.g., 16 Mbit chip takes ~5–8 minutes).
Programming: 2–3x faster than legacy ATMEGA8-based programmers.
Adapters & Tools:
SOIC8/SOP8 Test Clip: Beryllium copper pins with anti-slip design for stable in-circuit programming.
SOP8/SOIC8 to DIP8 Adapter: Converts surface-mount chips to DIP8 for breadboard compatibility.
EZ Programmer Socket: 150mil spacing for secure chip placement.
Software Compatibility: Works with NeoProgrammer, AsProgrammer, FlashROM, and CH341A official utilities.
CH341A USB Programmer ×1 (Supports 24/25-series EEPROM/SPI Flash).
1.8V Voltage Adapter ×1 (for low-voltage chip programming).
SOIC8/SOP8 Test Clip ×1 (beryllium copper needles, no soldering required).
SOP8/SOIC8 to DIP8 Adapter ×1 (150mil spacing, EZ programming socket).
USB Cable ×1 (standard USB-A to USB-B connector).
Repair: Recover corrupted BIOS/UEFI on motherboards, laptops, or GPUs.
Data Management: Backup, erase, or modify firmware on routers, TVs, set-top boxes, and automotive ECUs.
Hobby Projects: Flash custom firmware for IoT devices, retro gaming consoles, or Arduino-compatible boards.
Security: Securely erase sensitive data from discarded electronics.
✅ Beginner-Friendly: No soldering needed; test clip enables in-circuit programming.
✅ Broad Compatibility: Supports thousands of 24/25-series chips and common 3.3V/1.8V SPI Flash.
✅ Portable & Affordable: Compact design ideal for fieldwork or home labs.
Driver Installation: Required for Windows (download from manufacturer’s site).
Test Clip Stability: Ensure proper alignment with chip pins to avoid read/write errors.
Voltage Check: Always verify chip voltage (1.8V or 3.3V) before programming.
