: Beyond the CH341A, it supports UsbAsp, AVRISP-MKII, Arduino, and FT232H programmers.
The brought several refinements that made it more stable than earlier builds: asprogrammer 21013
: It is frequently the "hero" of technical stories where users "un-brick" expensive hardware (like motherboards or GPUs) that failed during a software update. Hardware Compatibility : It supports various programmers including Potential "21013" Connections Project/Issue ID : Beyond the CH341A, it supports UsbAsp, AVRISP-MKII,
The CH341A outputs logic HIGH at 5V, even when you select "3.3V mode" in software. ASProgrammer 21013 cannot fix this hardware flaw. : Beyond the CH341A
