CH341A USB Programmer kit for incircuit EEPROM and flash work What it is A compact USB programmer built around the CH341A USBtoTTL chip, supplied with a SOIC8 test clip and a 1.8V adapter for safe, incircuit programming of common EEPROM and flash chips. Key benefits Easy incircuit programming and diagnostics for EEPROMs such as 24CXX, 25CXX, and 93CXX without desoldering chips. Automatic chip model detection and read/write indicators simplify workflows and reduce guesswork. Flexible voltage support: selectable 1.8V adapter plus native 3.3V and 5V output options to match target device requirements. Stable data transfer ensured by an onboard 12 MHz quartz oscillator for reliable reads and writes. Compact, hobbyistfriendly solution that meets the needs of DIY electronics hobbyists and technicians. What is included CH341Abased USB programmer module. SOIC8 test clip compatible with SOP8 chips at 1.27 mm pitch. 1.8V adapter for lowvoltage devices. SOP8 to SOP16 adapter and 4pin headers for expanded connectivity. Multifunction extension pins and 12 MHz quartz oscillator for stable operation. Compatibility and form factor Supports EEPROM and flash families 24CXX, 25CXX, and 93CXX. Output voltage options: 1.8V (adapter), 3.3V, and 5V. SOIC8 test clip designed for SOP8 packages with 1.27 mm pitch; works with both widebody and narrowbody SOP8 chips for nondestructive connection. Includes headers and adapters that increase connectivity options for different board layouts and package types. Main functions Read, write, erase, and backup flash and EEPROM contents. Automatic detection of supported chip models to accelerate setup. Visual read and write indicators for clear status feedback during operations. Incircuit programming capability to keep components on the board while working. Practical use scenarios BIOS recovery and updates on motherboards by reading and writing EEPROM contents without removing the BIOS chip. and firmware recovery for routers, TVs, and other consumer electronics that use 24 and 25 series flash memory. Data backup and calibration tasks for embedded systems during troubleshooting or development. Why choose this kit This programmer kit combines voltage flexibility, automatic chip detection, and a nondestructive SOIC8 test clip to make EEPROM and flash programming more efficient and less error prone. It is well suited for hobbyists, technicians, and field service tasks where convenient, reliable incircuit access matters.
