Origin89 camera

Circuit specified, first copper drawn, nothing fabricated.

A trail camera that sends its pictures to the cabin over a Wi-Fi HaLow mesh, so a site four hours from a road can be looked at without driving out. One board, populated three ways: the camera, a relay that extends the mesh, and the base at the cabin that talks to the controller. The processor is the ESP32-P4 with a MIPI camera, chosen for night pictures; the radio is a HaLow module.

File	What it is
CAMERA-MESH.md	The product: what it does, the mesh, the power budget, what has to be measured before anything is built
board/CAMERA-NODE.md	The circuit specification the schematic is drawn from: blocks, rails, pin budget, the decisions left to draw time
board/CAMERA-LAYOUT.md	The placement and routing rules, numbered C-nn, with their reasons
board/layout/	The placement and routing scripts that produced the first copper, in the order they run
drawings/	The build and schedule drawings

Every part is a candidate until it has been picked with its datasheet open. The next step is the night-picture test on the P4 evaluation board; the schematic is drawn against the result, not before it.

Design source and exports

Design source: board/easyeda/origin89-camera.eprj2, the EasyEDA Pro project of this board alone, split out of the controller's. Export of 2026-09-09: board/build/2026-09-09/, Gerbers, bill of materials, pick-and-place, schematic PDF, STEP and one DXF of every layer. The STEP is in Git LFS, so install git-lfs before cloning or it comes down as a pointer file; it carries every part but C59, which has no model. Nothing has been fabricated from it.

The Gerbers are checked by tools/validate_gerbers.py, the same script the hardware repository runs on the controller, against board/gerber-rules.json: the C-02 keep-outs at the four mounting holes and the C-11 antenna void, layer by layer. It runs in CI on every push and it is red on the 2026-09-09 export: the ground pour reaches every mounting hole on all four layers, 29 mm² of copper inside the 3.5 mm keep-out at each, where C-02 wants none and C-03 wants the hole on no net. The fix is the controller's: a prohibited region at each hole on every copper layer, then the pours rebuilt. It is tracked as issue #1, and the check goes green when the next export passes. Nothing has been fabricated from this export, so no board carries the fault.

Exports are filed with tools/import_easyeda_export.py board <export folder>, the same way the hardware repository files the controller's: the date becomes the directory and each file gets the name its kind always gets.
