9-Piece CH341A USB Programmer Kit 1.8V Adapter Board & SOP8 SOIC8 Test Clip. EEPROM SPI Flash Module for 24 25 Series: SOP16 SOP28 BIOS Flasher, Router Motherboard Recovery Tool

【EEPROM Flashing & System Recovery】 Engineered around the CH341A architecture, this USB programmer functions as a primary diagnostic tool for 24cxx and 25cxx series SPI flash chips. The hardware supports standard BIOS recovery and unbricking procedures for PC motherboards, set-top boxes, network routers, and LCD TVs, while maintaining full operational compatibility with open-source software interfaces including flashrom. 【PCB Architecture & Circuit Protection】 The main unit utilizes a black-gold PCB substrate featuring CNC-machined structural edges to minimize direct soldering requirements. A 500mA self-recovery fuse is physically integrated into the circuitry to automatically isolate exposed pins, computer ports, and connected components from sudden electrical short circuits during operation. 【Multi-Voltage & Chip Package Configurations】 Hardware includes a dedicated 1.8V adapter board alongside native 3.3V and 5V power outputs. The kit features an SOP8 SOIC8 test clip for in-circuit interfacing, coupled with SOP16, SOP28, and DIP8 modules. This structural design accommodates 1.27mm pitch wide and narrow body chips across 150mil, 200mil, and 300mil specifications, including the high-capacity w25q64, w25q128, and w25q32 series. 【USB to TTL & Microcontroller Interfacing】 The customized primary board exposes standard SPI pinouts and dedicated TTL interface connections (RXD, TXD, GND). This specific configuration allows the module to operate as a direct USB to TTL serial converter for serial debugging and online microcontroller programming, functioning compatibly with Atmega and equivalent MCUs. 【Operational Diagnostics & Clip Handling】 Integrated onboard LED indicators provide real-time visual feedback for current power status and read/write data transmission cycles. To prevent physical damage to the hardware during disassembly, the in-circuit test clip must be manually pinched open for alignment prior to clamping and must never be removed by applying direct pulling force.
