Shenzhen Dianmao Technology Co., Ltd. is a Chinese educational-software house that focuses on lowering the entry barrier for children and teenagers who want to create with code. Its catalogue revolves around two complementary tools: the Source Code Smart Manufacturing Editor, a visual, block-based IDE that now exposes both digital and analogue hardware pins so learners can toggle LEDs, read sensors or drive motors from the same drag-and-drop canvas, and that also supports simultaneous multi-board connections for classroom-scale robotics projects; and Programming Cat Custom Courses, a game-like desktop player that turns curriculum-mapped Python, C and AI lessons into quest chains, awarding collectible badges for every loop, function or debug solved. Together the products cover the typical STEM workflow—design on screen, compile, flash to micro:bit, Arduino or custom boards, then test in real time—while embedding assessment dashboards for teachers and cloud saving for students. Because the toolchain is bilingual and hardware-agnostic, it is equally at home in primary-school maker clubs, after-school coding centers and provincial innovation contests. All Shenzhen Dianmao applications are offered free of charge on get.nero.com, delivered through trusted Windows package sources such as winget, always installing the newest builds and allowing batch deployment of the entire studio suite.
