NeoProgrammer (often distributed with names like NeoProgramer or NeoProgrammer V2.x) is a Windows utility used to read, write, and verify firmware on EEPROM/flash chips via USB programmers (commonly CH341-based devices and some USB-to-SPI/I2C adapters). Version identifiers such as “21019” are not a standard public semantic version from a vendor but appear in community distributions or repository filenames; the software is commonly circulated on GitHub, hobbyist forums, and in zipped packages posted alongside open-source forks for specific programmer hardware.
EEPROMs: Includes I2C (24Cxx), SPI (25xxx, 95xxx, 45xxx), and MicroWire (93Cxx). neo programmer 21019 download link
