Allows you to modify parameters (like MAC addresses, serial configurations, or regional tags) straight in the buffer layout before triggering a write procedure.
Enhanced support for I2C devices such as AT24RF08 , PCA24S08 , and specific SPI EEproms like M35080/M351xx .
is a widely acclaimed version designed for enhanced stability and expanded chip support, replacing older versions like AsProgrammer 2.1.0.13. Key Features and Improvements

Do not run the "Auto" function on unknown chips. Read the datasheet first, or you might erase a security fuse. Ask me how I know.
The original software that ships with generic CH341A hardware is notorious for data verification errors, slow write cycles, and restricted device lists. This utility resolves those restrictions completely. Key Features of NeoProgrammer 2.1.0.19
: Always read the original chip data twice and save them as separate files. Compare their MD5 checksums Allows you to modify parameters (like MAC addresses,
: Enables direct editing of binary contents, allowing you to alter MAC addresses, inject serial keys, or clear password regions before executing a write sequence.
