CH341A 24 25 Series EEPROM Flash BIOS USB Programmer

The CH341A programmer is a USB-to-SPI/I2C/Parallel tool designed for programming and troubleshooting EEPROM (24/93 series), BIOS Flash (25 series), and other storage chips. Powered by the CH341A chip, it provides a straightforward interface for communicating with microcontrollers and external memory via a standard USB port.

This module is ideal for backing up, copying, and rewriting BIOS firmware, as well as reading/writing EEPROMs in electronics projects or repair work. It comes with test clips (SOIC8/SOP8 clip) allowing you to program chips directly on-circuit without soldering, which helps preserve fragile components.
