: Known for providing a comprehensive Arduino Library for Proteus that includes various boards.
Proteus Design Suite is a proprietary software tool used primarily for electronic circuit design, simulation, and printed circuit board (PCB) layout. While Proteus includes built-in models for standard 8-bit AVR-based Arduinos (such as the Uno and Nano), the Arduino Due—based on the Atmel SAM3X8E ARM Cortex-M3 processor—often requires an external library to be imported into the software for successful simulation. arduino due library for proteus free download
: This is the most popular source. They offer several versions (V2.0, V3.0) of their Arduino Library for Proteus . Note that earlier versions only included AVR boards, but they have worked on adding advanced boards like the Arduino Due in more recent updates. : Known for providing a comprehensive Arduino Library
