CONDUIT

Open-hardware RP2350 / Pico2 board with Power-over-Ethernet, an RMII PHY, and a browser-based development workflow. The repo holds the KiCad project (hardware/), the firmware with A/B-partitioned OTA + a tiny HTTP API (firmware/), the conduit Python CLI for build / flash / OTA / commanding (tools/conduit/), and a static web IDE that compiles user C in the browser via WASM clang+lld and pushes it over the network (web/).

First-time setup

1. First flash (USB). Hold BOOTSEL while plugging the board into USB — it enumerates as the RPI-RP2350 mass-storage drive. Download the latest commissioning image — currently factory-10.2 — and copy the .uf2 file onto the drive. The drive disappears, the board reboots running the new firmware. The image is built by .github/workflows/commissioning-image.yml and contains the bootloader plus a non-TBYB app concatenated into one UF2.
2. Power and network. Connect the board to a PoE-capable switch (or keep it on USB power); it tries DHCP first and falls back to 192.168.178.200/24.
3. Iterate. Open the web IDE in your browser, point it at the device's IP, and from there you write user C, build + OTA over the network, watch live telemetry charts, and send commands to the running firmware — all without leaving the browser.
