Click the "IC" button, select the family (e.g., SPI Flash), manufacturer (e.g., Winbond), and exact model (e.g., W25Q64FV).
If you are deep into the world of hardware hacking, BIOS recovery, or motherboard repair, you have almost certainly encountered the . This little black (or green) USB programmer has become the unofficial Swiss Army knife of the electronics bench. It is cheap, ubiquitous, and gets the job done.
I cannot stress this enough. If you don't backup, you cannot restore if the flash fails. Conclusion neoprogrammer 21 019 ch341a best
: Beyond common 25-series SPI Flash and 24-series I2C EEPROM, version 2.1.0.19 supports specialized 93-series Microwire protocols, Nuvoton chips, and certain Embedded Controllers (EC). Key Technical Features Performance Capabilities Supported Protocols
NeoProgrammer is a free, third-party programming software designed specifically for the CH341A USB programmer. It is based on AsProgrammer 2.1.0.13 but has been significantly enhanced and modified to support a much wider range of chips and offer advanced features that the original software lacks. The version 2.2.0.10 is widely considered the most stable and feature-rich release, making it the go-to choice for anyone using a CH341A programmer. Click the "IC" button, select the family (e
This is the secret feature. The CH341A can also program 24CXX series EEPROMs (used for Keyboard Controllers and monitor firmware). Select "I2C EEPROM" from the chip type dropdown. Most other programmers require a separate $50 device. NeoProgrammer 2.1.0.19 unlocks this on your existing CH341A for free.
