Outdoor embedded device for exploration
Nomad is a custom outdoor mobile device built around the ESP32-S3. It is designed for explorers, researchers, and outdoor enthusiasts who need reliable positioning, long-range communication, environmental awareness, and practical survival utilities in a compact rugged package. I made this project entirely myself, the idea comes from my passion of making useful objects that help people in specific actions.

- Staying connected through long-range LoRa messaging.
- Understanding local conditions through environmental sensing.
- Conserving energy through deep sleep and power-aware firmware.
- Providing simple, fast interaction through buttons and a menu-driven UI.
- Accessing to useful survival tips

Questions
How big is the Nomad PCB?
It measures 65 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nomad use?
81 parts, built around the E220-900T22S, ESP32-S3-WROOM-1-N8, NEO-M8M and BME280. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Nomad KiCad files?
From the 0Zane/Nomad repository on GitHub, at the commit this page was made from: the board is pcb/nomad.kicad_pcb and its schematic pcb/modules.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nomad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
