Solar-Powered LoRa/GNSS Controller

Project overview

Solar/battery-powered field controller combining charging, LoRa communications, GNSS/GPS positioning and an ESP32-class processor.

Engineering approach

Power electronics work lives or dies on thermal design and conversion efficiency, with layout decisions directly affecting how much heat a board has to shed. On this board, that translates into a component set built around 4L and SX1262 LoRa, with layout and stack-up decisions driven by power conversion efficiency, thermal management, and accurate current and voltage sensing.
