The latest reported version of NeoProgrammer for the CH341A USB programmer is v2.2.0.10, released on May 31, 2024. This tool is a popular alternative to AsProgrammer, used by technicians for reading, writing, and repairing memory chips like EEPROM and SPI Flash. Key Features in Version 2.2.0.10
- Driver Conflicts: Windows 11 (23H2 and newer) has tightened driver signature enforcement. Old Neo Programmer drivers (pre-2022) often trigger "Code 52" errors or BSODs. The latest version ships with signed WinUSB drivers that are fully WHQL certified.
- Chip ID Collisions: Older databases often misidentified chips, leading to writing a firmware meant for a 2MB chip onto a 16MB chip, effectively bricking the target device.
- Write Corruption: A bug in the write buffer handling of the 2021 version caused the last 64 bytes of data to drop when writing certain 24CXX EEPROMs. This bug is squashed in the latest release.
