Chip selections, measured results, and the mistakes we learned from — written by the engineers who shipped them.
The end-to-end hardware design flow we follow — schematic capture, multi-version PCB iteration, and signal integrity — illustrated with three real board designs.
How to get a working hardware prototype in weeks, not months — prototyping strategy, iteration discipline, and power-budget lessons from real builds.
How we ship LVGL graphical interfaces on low-cost MCUs — memory budgets, frame-rate tuning, and when to choose LVGL over TouchGFX, drawn from three delivered products.
The full IoT stack we build — low-power sensor nodes, LPWAN connectivity, and cloud backends — with lessons from a five-month smart agriculture deployment.
How we structure firmware with FreeRTOS — task partitioning, real-time scheduling, and filesystem integration — based on three shipped embedded products.
What it actually takes to bring up embedded Linux on a new board — CAN bus data acquisition on i.MX6 and a full OpenWrt smart-home router.
A practical guide to WebRTC app development — when to self-host signaling, how embedded devices like ESP8266 join browser calls, and why Speex still beats Opus on tiny silicon. Lessons from four shipped projects.
