Bill of materials
This page is kept as a compatibility entry point for older links. The Entrance Observer BOM is now organized by development phase so each bill of materials matches a concrete build goal.
Current BOM structure
| Phase | Purpose | BOM |
|---|---|---|
| Phase 1 - Lab validation | Jetson Orin Nano bench setup for camera, model, telemetry, and on-demand video validation. | Phase 1 - Lab BOM |
| Phase 2 - Field MVP | Weather-protected pilot unit for one real hive entrance. | Phase 2 - Field MVP BOM |
| Phase 3 - Production kit | Repeatable, supportable production device or SKU family. | Phase 3 - Production BOM |
Why the BOM was split
The previous single BOM described the current Jetson Orin Nano prototype. That was useful for ordering lab parts, but it mixed three different decisions:
- what a developer needs on a bench;
- what a beekeeper needs for a first outdoor pilot;
- what Gratheon needs for a repeatable production kit.
Those phases have different cost, power, enclosure, camera, networking, service, and manufacturing requirements. The phase-first structure prevents a lab convenience part, for example a touchscreen or acrylic case, from being treated as a production requirement.
Current prototype summary
The current lab prototype still uses:
- NVIDIA Jetson Orin Nano Super Developer Kit;
- USB UVC 4K camera;
- manual varifocal CS/C lens;
- NVMe SSD for OS, logs, and clip buffering;
- WiFi or Ethernet for development;
- temporary camera mount and fixture materials.
