Designing Hardware Products

This is a full stack hardware development pipeline that takes you from a product brief to Gerber files, compiled ESP-IDF firmware, and a cross-platform mobile app without manual handoffs between phases. It's deliberately opinionated about the toolchain (ESP32 variants, KiCad, UniApp) and orchestrates them through five sequential phases you can run or skip individually. The pitch is zero-human-touch automation, which is ambitious for hardware where physical constraints matter, but the phase structure is solid and the references cover real gotchas like high voltage topology and KiCad 9 quirks. Best for IoT products where you're starting from scratch and comfortable with the ESP-IDF ecosystem. If you're doing something exotic or already have half the stack built, you'll spend time working around the assumptions.
