CH341A, UsbAsp, Bus Pirate, Arduino, AVRISP (LUFA), and FT232H. Supported Chip Types:
To help you decide, here's a comparison table of AsProgrammer against its main alternatives:
: A portable version of 2.1.0.13 is often shared via Google Docs/Drive by community members.
Built-in editing features allow users to modify specific bytes of a firmware dump directly inside the application before executing a write command. Asprogrammer 2.1.0.13 Download
It's important to note that this version has been superseded by newer releases. The official GitHub repository ( nofeletru/UsbAsp-flash ) shows the latest version as . A popular derivative, NeoProgrammer (v2.2.0.3) , is also based on AsProgrammer 2.1.0.13 and supports over 1,600 chips. While newer versions exist, 2.1.0.13 remains a solid, widely tested choice.
Unlike legacy flashing utilities that glitch outside of legacy environments, version 2.1.0.13 provides full support for Windows XP, 7, 8, 10, and 11 .
Use the , Erase , and Write icons on the toolbar to manage your firmware. CH341A, UsbAsp, Bus Pirate, Arduino, AVRISP (LUFA), and
Absolutely. While newer programming hardware (like T48 or TL866II) comes with its own software, Asprogrammer remains the go-to solution for the budget-friendly CH341A. Version 2.1.0.13 strikes the perfect balance between features and stability. It’s lightweight enough to run on an old Windows XP laptop in a workshop, yet powerful enough for professional board repair.
is a highly efficient, open-source alternative flashing software designed to control popular hardware flashers like the CH341A USB mini programmer and USBasp . When modifying motherboard BIOS, reviving bricked routers, or modifying automotive EEPROM chips, the stock software packaged with cheap programmers frequently fails, throws execution errors, or fails to recognize modern high-capacity chips. AsProgrammer v2.1.0.13 provides a streamlined, lightweight, and incredibly stable utility that fixes these constraints, cementing itself as an essential tool for technicians and hardware enthusiasts alike. Why Choose AsProgrammer 2.1.0.13?
| Problem | Solution | | :--- | :--- | | Chip not detected | Check connections. Lower speed in settings (e.g., SPI speed to 1 MHz). | | Verification failed | Poor contact. Clean chip pins or use lower programming voltage. | | Driver error on Windows 10 | Disable driver signature enforcement temporarily or use a signed driver. | | Asprogrammer crashes on start | Install .NET Framework 4.8.

Avoid third-party "download sites" (e.g., softpedia, uptodown, random driver sites) – they often bundle adware or outdated builds. Only use GitHub or the developer’s trusted repository.
Always perform a Verify after writing to ensure the buffer matches the chip's content. ⚠️ A Note on Voltage
Includes a built-in hex editor. You can modify firmware directly before flashing—a lifesaver for patching BIOS logos or MAC addresses.
