💀 BRIEFING

Nebula is not just another ESP32 dev-board. It is an ultra-compact, modular handheld platform designed for advanced sensor monitoring, high-current PWM control, and researching airflow dynamics. Built around the ESP32-S3 WROOM-1, featuring an Always-On E-Ink display and a complex sensor array. The device is powered by a high-density energy stack and encased in a custom shell.

Disclaimer: This device includes high-current output drivers. It was designed for educational purposes, pneumatics research, and thermal control experiments.
