NeoProgrammer (a later fork) added Chinese telemetry and forced updates. The official ASProgrammer GitHub version dropped CH341A fast mode. The sits in a sweet spot—no bloat, no cloud calls, and perfect compatibility for legacy XP-era repair benches.

While many users look for pre-compiled, zipped versions of AsProgrammer 2.1.0.13, advanced users and developers often compile the software themselves. The project is primarily built using the (an open-source Delphi-like environment).

Hardware enthusiasts prefer this specific build over stock manufacturer software due to its deep stability patches and extended chip support database. Click Read ID to ensure the software communicates

Before we focus on the exclusive 2021 build, let's establish a baseline. ASProgrammer is a free, open-source (or freemium) software used to read, write, and erase SPI (Serial Peripheral Interface) flash memory chips. It is the preferred alternative to commercial software like CH341A Programmer Software because it supports a wider range of chips, including NAND flashes, and offers better stability.

The CH341A driver is unsigned. Reboot your PC and press (or Shift+Restart -> Troubleshoot -> Startup Settings -> Disable driver signature enforcement).

Many older versions of ASProgrammer had signature issues on Windows 10 after the 2020 update. Version 21013 was the first to natively include patched drivers that bypass Microsoft’s driver signature enforcement without requiring permanent test mode. The sits in a sweet spot—no bloat, no

The 21013 exclusive has a memory limit of 64MB for the GUI. For 128MB chips (W25Q512), use the CLI version only. Or split the file into two halves (using HxD) and write them sequentially.

The 2021 exclusive is sensitive to cable length. Use a 15cm (6-inch) USB extension max. Or, go to Hardware Settings -> Reduce "SPI Clock" from 24MHz to 12MHz.
