Learn how to create custom board definitions for Zephyr RTOS in this 42-minute tutorial video from Digi-Key. Discover the complete process of setting up a custom board named "nyan" based on the ESP32-S3 SoC and integrating it into the Zephyr ecosystem. Master the essential steps for configuring board.yml, device tree sources, and Kconfig files, then implement a simple LED-blinking application to test your custom board's functionality. The video breaks down existing board definitions, walks through CMake configuration, YAML setup, Kconfig options, and devicetree implementation before demonstrating how to write and run a demo application. By the end, gain the knowledge needed to adapt Zephyr to your own hardware for IoT, robotics, and other embedded projects, with additional resources provided for further learning and a challenge to enable I2C or SPI on your custom board.
