These are the full-stack builds: a sensor on one end, a dashboard on the other, and everything in between — WiFi, MQTT, cloud APIs, and battery strategy. If you’re moving from blinking LEDs to systems that run unattended for months, start here. The boards below are the ones we reach for in our own client work.
