Description

The owner asked (2026-09-25) to re-examine the Air Hub platform under three new inputs: a single Linux SoC plus one radio chip; industrial-grade (-40…+85 °C) silicon is required; and two single-radio variants instead of one multi-radio product: variant 1 Linux + 2.4 GHz (BLE / Zigbee / Thread-Matter, one function at a time, selected by the radio firmware image), variant 2 Linux + sub-GHz (LoRa and 433 MHz). The owner asked to add RK3506J as an alternative platform and to collect radio-chip candidates.

Deliverable: one evaluation page under bizplan/product/switch/air-hub/evaluations/ (Allwinner / Rockchip / SigmaStar industrial SoCs, radio candidates per variant, BOM estimate with sourced prices), its row in the package index, and RK3506J recorded as the alternative main controller in the design appendix. No Level 1 value changes.

Acceptance criteria:

1. Every price and chip figure carries a source and date.
2. The page states it is an evaluation and cites the spec only through AIR-O-03 / AIR-O-09.
3. bun run docs:lint && bun run docs:build && git diff --check passes.
