This paper provides a comprehensive technical and pedagogical analysis of mBlock version 3.4.12, a significant legacy release developed by Makeblock based on the Scratch 2.0 offline editor. As a bridge between graphical programming and textual coding, mBlock 3.4.12 played a pivotal role in STEM education by enabling seamless hardware interaction with Arduino-based platforms. This paper examines the software's architecture, its implementation of the "Scratch to Arduino" translation mechanism, extension compatibility, and the specific stability characteristics of the 3.4.12 build. Furthermore, it discusses the software's relevance in modern educational contexts, particularly for institutions maintaining legacy hardware or requiring offline functionality on older computing systems.
