Score: 6.5/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 6)

LWDT is a lightweight device-tree and driver framework for ESP-IDF, inspired by Zephyr RTOS, that enables hardware abstraction across multiple board variants without runtime overhead. It addresses the common pain of #ifdef spaghetti and duplicated driver glue in ESP-IDF projects, making it a practical tool for ESP32 developers building multi-variant products.

Target audience: embedded engineers, firmware developers, iot developers
