The CH341A/B Programmer Complete Set is an essential USB-based EEPROM and SPI flash programming tool for 24 and 25 series chips. It provides a simple way to read, write, erase, and verify EEPROM data, making it ideal for BIOS updates, firmware repair, and IC testing. Equipped with a SOIC8/SOP8 test clip, it allows in-circuit programming without desoldering the chip. Supporting both 3.3V and 5V operation, the programmer is compatible with a wide range of devices and microcontrollers. Featuring stable communication through TXD, RXD, and POWER LEDs, it is a must-have for embedded system developers, hardware engineers, and repair technicians. Features: Supports 24 and 25 series EEPROM chips Includes SOIC8/SOP8 test clip for in-circuit programming Compatible with Windows 7/8/10 systems Dual power modes: 3.3V and 5V selectable Built-in TXD, RXD, and Power indicator LEDs Stable USB communication using CH341 chip Supports read, write, erase, and verify operations Ideal for BIOS/firmware updates and IC testing Package Includes: 1 x CH341A B Programmer Complete Set
