NeoProgrammer is a community-driven, enhanced version of the open-source "AsProgrammer" project. Specifically, version is a stable and highly recommended release that has turned the CH341A from a basic EEPROM writer into a versatile multi-chip programmer.
Unlike the restrictive older software, the 2.1.0.19 version introduces critical engine stability updates and widened IC database support.

The NeoProgrammer 21-019 CH341A consists of the following components:
NeoProgrammer supports an extensive range of memory families: : Standard chips found in most PC BIOS. NeoProgrammer is a community-driven, enhanced version of the
Desolder the target component using a hot-air rework station and place it into an appropriate SOP8-to-DIP8 adapter frame. Lock this adapter securely into the 25XX portion of the ZIF socket. This eliminates circuit noise and provides 100% stable read/write validation loops. 2. In-Circuit SOP8 Test Clip
: It works with a vast range of chips including SPI NOR flash , I2C EEPROMs (24Cxx) , MicroWire (93Cxx) , and even experimental support for SPI NAND . (button “Read ID”) – confirms communication
: Plug in your programmer. Open NeoProgrammer and click "Detect IC" . If it fails, check your chip's orientation (Pin 1 must match the board diagram).
