CH341A USB BIOS EEPROM Flash Programmer Kit – SOP8 & 1.8V
CH341A USB Flash Programmer Complete Kit
Take full control of BIOS chips, EEPROM modules, and Flash memory ICs with this comprehensive CH341A/CH341B USB programmer bundle. Whether you're recovering a corrupted BIOS, re-flashing firmware, or reading and writing serial memory chips, this all-in-one kit gives you everything you need in a single package. Made in Mainland China.
What's Included in the Kit
- CH341A/B USB Programmer – Wide compatibility with 25 and 24 series EEPROM and Flash chips
- SOP8 Test Clip – In-circuit chip reading/writing without desoldering; clamps directly onto the IC
- SOIC8 to DIP8 Adapter – Lets you mount SOIC8 surface-mount chips into the programmer's ZIF socket
- USB Cable – Connects the programmer to any standard USB-A port on your PC
- 1.8V Adapter – Essential for reading and writing modern low-voltage (1.8V) Flash and EEPROM chips that would otherwise be damaged by the standard 3.3V output
- ZIF Socket Adapter – Zero Insertion Force socket for easy, damage-free chip seating
Key Features

Frequently Asked Questions
Q: What is the 1.8V adapter used for in the CH341A programmer kit?
A: Many modern Flash and EEPROM chips — particularly those found in ultrabooks, tablets, and embedded systems — operate at 1.8V. The standard CH341A programmer outputs 3.3V, which can damage these low-voltage chips. The included 1.8V adapter steps down the voltage so you can safely read and write 1.8V ICs without risk of damage.
Q: Do I need to desolder the chip from the board to use this programmer?
A: Not necessarily. The included SOP8 test clip allows you to connect directly to most SOP8/SOIC8 chips while they remain soldered on the board (in-circuit programming). However, results can vary depending on other components on the board, so desoldering and using the ZIF socket or SOIC8 adapter is recommended for the most reliable read/write operations.
Q: Is this CH341A kit compatible with Windows 10 and Windows 11?
A: Yes. The CH341A USB programmer is compatible with Windows 7, 8, 10, and 11. You may need to install the CH341A driver (freely available online) the first time you connect it. Once installed, it works with popular free programming software such as AsProgrammer and NeoProgrammer.
Q: What chip types does this programmer support?
A: This programmer supports a wide range of 24 series I²C EEPROM chips (e.g., 24C01 through 24C512) and 25 series SPI Flash chips (e.g., W25Qxx, MX25Lxx, SST25xx). It is widely used for BIOS chip flashing on desktop motherboards and laptops.
