Creating a Custom Info Station Using Phoenix Framework and ESP32

This article explores the creation of a smart information display system using the Phoenix Framework for the backend and an ESP32 microcontroller with an E-Ink display for the frontend. The project aims to provide users with quick access to public transport schedules, weather updates, and other important information without needing to check their phones. The author discusses various hardware choices, including selecting low-power devices and battery-efficient components. Detailed architectural designs emphasize using Phoenix for serving content, leveraging SVG for rendering, and the feasibility of running Elixir on microcontrollers via AtomVM. The article also outlines considerations for deploying the application on a Raspberry Pi and the necessary steps to manage resources effectively, showing how users can implement their unique projects using Elixir and Nerves.
