CH341A CH341B USB EEPROM BIOS Flash Programmer with SOIC8 Clip, Dual Voltage, Automatic Chip Recognition

This compact USB programmer module provides a versatile and reliable way to read, write, and debug 24 series EEPROMs and 25 series SPI flash chips. Built around the CH341A and CH341B interface chips, the module combines automatic chip recognition, integrated USB to TTL serial support, and flexible power output to simplify common programming and tasks. Key features and benefits Broad chip support: Works with 24 series EEPROM and 25 series SPI flash devices in 8 pin and 16 pin packages. Automatically recognizes 25 series chips for faster setup. Integrated USB to TTL interface: Use the USB to TTL port for serial communication, direct device access, and firmware operations without a separate adapter. STC microcontroller support: Supports downloading firmware to STC series singlechip microcontrollers for incircuit programming and updates. Power output options: Builtin 5V and 3.3V power supply outputs allow safe operation of both low voltage and standard devices. Visual status feedback: Separate indicator lamps for 24 and 25 series activity provide immediate confirmation of operations. Expandable SPI access: Dedicated SPI pins allow easy connection to custom adapters, test clips, or breakout boards to extend functionality. SOIC8 SOP8 test clip compatibility: Designed to work with common 8 pin test clip setups for insocket programming. Small footprint: Compact dimensions 70 mm x 27 mm fit easily on a workbench or inside test rigs. Practical applications BIOS or firmware recovery: Read and rewrite SPI flash chips on motherboards, routers, and embedded devices to recover corrupted firmware. EEPROM and flash programming: Update or clone configuration data on 24 series EEPROMs and 25 series SPI flash ICs for and manufacturing tasks. Microcontroller firmware flashing: Program or update STC series singlechip microcontrollers during development, testing, or field repairs. Technical notes Condition , SMD packaged module. Designed for use with 8 pin and 16 pin SPI and EEPROM chips. Ensure correct voltage selection and wiring before connecting to target devices. Module dimensions 70 mm x 27 mm. This module is a practical tool for engineers, technicians, and hobbyists who need a compact, multifunction programmer with USB to TTL capability, automatic chip recognition, and flexible power options.
