From the project

A Raspberry Pi Zero 2W shield built from a copy of the Sofar Bristlemouth mote: ADIN2111 two-port 10BASE-T1L with PoDL, powered from the bus, 5 V for the Pi, a 24 V payload port, and a ~50 W power path (absolute max at 24 V). Potted.

Claude Code does the schematic capture, up to a design-review package. Nick reviews, lays out, routes and brings up the board.

- Agents: start with CLAUDE.md, then /agent-entry. - People: docs/TRACKER.md shows where things stand; docs/SPEC.md says what we're building and why. - Close KiCad before an agent edits the project.
