Description

After the owner's design updates (Air Hub on an RK3506G core board sharing the Pro carrier, Air Hub Mini on ESP32-C6-WROOM-1-N8 without Linux, no ignition protection and no class type approval), the owner asked to review them and then handle the PCB and schematics ("我更新了设计， 你看看再处理pcb和原理图").

Acceptance criteria:

1. The RK3506G core-board pin table is compared with the J table; any pin the carrier uses that differs is recorded.
2. The shared carrier generator produces two projects from one netlist: air_hub_pro (433 MHz link fitted, HD-RK3506J-256F256LI) and air_hub (433 MHz parts not fitted, HD-RK3506G-128F256LW); both pass ERC and the netlist check; the Pro board stays the carrier layout.
3. Air Hub Mini has a schematic (air_hub_mini, ESP32-C6-WROOM-1-N8, EFR32MG21, W5500, TJA1463, the same input protection and filter) and a first placed and routed board through the same flow with a clean DRC; the EMC rule check is run on it.
4. The reference-board page records the variants, the Mini schematic and board, and the parts; the quality gate passes.

Notes

Plan: 20261013-0905-air-hub-shared-carrier-and-mini-board

• complete: Three schematics pass ERC and verify_net.py (604 / 604 / 404 pins); Pro and Mini boards pass KiCad DRC with 0 unconnected, 0 clearance or short errors, 0 parity differences; docs lint, docs:build and git diff --check pass.
