# Welcome to the ST-LINE technical blog > We're opening a space to share the technical decisions, field lessons, and tools we use to build electronics, firmware, software, acoustics and medical devices. Published: 2026-03-24 Category: regolatorio Tag: meta, blog Page: --- This blog collects our daily technical work across five areas: analog and mixed-signal hardware, real-time firmware, desktop and web software, environmental and architectural acoustics, regulatory pathways for medical devices. ## What you'll find here We won't write marketing posts: articles will start from code, schematics, and lab measurements. When a technical choice didn't work we'll write it down, with the reason: that is the part a reader needs, and the part that is usually missing. ## The five categories **Hardware** — schematics, layout, component choices, mixed-signal and RF cases. **Firmware** — bare-metal and RTOS, drivers, protocols, embedded debug. **Software** — cross-platform desktop, backends, web platforms, integration. **Acoustics** — measurements, regulatory assessments, passive design. **Regulatory** — IEC 60601, IEC 62304, ISO 13485, MDR, 510(k), MDSAP. ## One blog, two languages Every article is published in Italian and English. Translations are curated, not automated: each post goes through editorial review before publication. See you in the next article.
