Native resistors/capacitors use explicit JLC numbers rather than an automatic parts engine. Other parts and local STEP/OBJ bodies were obtained through tscircuit's JLC import flow. Supplier CAD/symbol data remain subject to their original terms; no blanket relicensing of vendor assets is asserted.

The power and interface design uses a common 3.192 V MCU/camera I/O supply, 1.296 V camera core, 0.1% main feedback resistors, 5 V analog-LDO input, controllable camera reset/powerdown, camera I/O decoupling and local ESD-supply bypass. USB-C supplies standard 5 V power.

Supplier STEP entity terminators were normalized from `) ;` to `);` for the pinned exporter’s parser. Geometry/entity arguments were not changed. `bun run normalize:step` reproduces this formatting operation after a fresh import. Assembled STEP export then completes without omitted-model warnings.
