Working notes on the engineering decisions behind connected hardware — written by Aditya Chilka, Founder & CEO of Rapid Circuitry.
BLE, Wi-Fi, LoRa/LoRaWAN, and cellular (LTE-M / NB-IoT) compared on range, power, bandwidth, and cost — a practical decision guide.
A practical DFM checklist for getting boards right on the first build — footprints, fab margins, assembly, panelisation, and test.
When to run ML on the device instead of the cloud, what fits in a few hundred KB of RAM, and how to ship TinyML on the ESP32, STM32, and nRF52.
The real stages — EVT, DVT, PVT — of taking an electronic product from working prototype to manufacturable hardware, and where schedules slip.
