Engineering approach
Connected products live or die on power efficiency and radio performance, so RF-aware layout and antenna matching are treated as first-class design constraints. On this board, that translates into a component set built around ESP32-S3 + ESP32-C5 and GPS, with layout and stack-up decisions driven by radio layout, antenna placement, power budget, and reliable wireless connectivity in real-world conditions.
