Description

Spec R1.0 selects two products: Air Hub (AH-19, RV1106G3 chip-down, alternate SSD202D, EFR32MG21, ESP32-C6 as Wi-Fi / configuration / CAN) and Air Hub Pro (AH-20, RK3506J stamp-hole core board, EFR32MG21, ESP32-C6, CMT2300A). The owner asked for the hardware plan of both: a reference-board definition (interfaces, pin budget, power tree), a concrete component list with part numbers and prices, and schematics, using the Vanxoak HD-RK3506J core board for the Pro.

Acceptance criteria:

1. A Level-2 design page P05-air-hub-design-reference-board.md describes both boards: block diagram, SoC / core-board pin allocation, power tree with rail currents, module-by-module circuit notes, and a component list per product with MPN, package, quantity, LCSC code and price.
2. KiCad 10 schematics for both boards exist under /srv/ybo/switch/air_hub/ and /srv/ybo/switch/air_hub_pro/, generated by tools/gen_air_hub.py and tools/gen_air_hub_pro.py, with ERC, netlist, BOM and PDF / SVG exports; ERC reports no real violations.
3. The design appendix, package index and changelog reference the new page; Level-1 values are unchanged; the quality gate passes (bun run docs:lint && bun run docs:build && git diff --check).
