STM32CubeIDE for VSCode, NanoH2 dev kit, and a CNC hot‑wire cutter (Jul 24, 2026)

🔧 Tool of the Week

STM32CubeIDE for Visual Studio Code — 3.10.0 A practical VS Code extension of STM32CubeIDE: better build analysis (ELF support), Zephyr integration, CLI project creation, and a few usability fixes that matter when you actually ship firmware. Good if you use STM32s and prefer VS Code over Eclipse. 🔗 https://community.st.com/stm32cubeide-for-visual-studio-code-mcus-133/new-stm32cubeide-for-visual-studio-code-3-10-0-released-167104
