Context

章节标题：“Context”
  • P05-air.md R0.9 §1 states "SoC 为 Nordic nRF54L15（QFN48…）, 没有首版备选 SoC"; §2 table row 电子平台 names the QFN48 chip; §7 lists the RED/CRA path without a module statement; §8 AIR-O-03 covers the SoC tier, order code and flash partitioning.
  • P05-air-design.md R0.7 §2.1 is titled "首版锁定：nRF54L15" with a row 替代形态 for "经验证的 nRF54L15 模组"; §3 block diagram and the peripheral table describe the chip-down build (32 MHz crystal, pi match, PCB inverted-F antenna, DC/DC inductor per Nordic); §5 lists the chip-down RF items (match, antenna keep-out) and the clock crystals.
  • P05-air-guide.md R0.4 §2 asks the RF work package for a tuning report, §5 EOL tests both crystals, §6 D0 demonstrates "nRF54L15 实板".
  • air/index.md line 15 and governance/product-plan.md line 184 summarise "BLE 版锁定 nRF54L15"; governance/compliance-matrix.md row Switch · Air says "Air 按单一 BLE 2.4 GHz 射频评估".
  • Hardware state (switch workspace): air-mod/ module build and air/ chip build both generated, ERC 0, DRC 0 errors. Module build host circuit: VDD_NRF 10 uF + 100 nF, 4.7 uH between DCC and DECD (DECD cap inside the module), 32.768 kHz crystal on the host (internal load caps), NFC loop + 2 tuning caps, reset 1k + 3.9 pF, TC2030 SWD pads; keys on P1.06/P1.10/P1.11/P1.12 and LED on P2.02/P2.03 because the module's inner pad row cannot be escaped with 0.15 mm rules; NFC1/NFC2 fanned out through vias under the module; antenna end at the board edge with the 5.0 x 2.9 mm no-copper area (Raytac 2.3).
  • Module facts (Raytac datasheet v1.1): nRF54L15 WLCSP inside, 6.4 x 8.4 x 1.5 mm, 1.7-3.6 V, 45 pads, +8 dBm, NFC-A pins, FCC ID SH6AN54LV (portable, no separation distance), IC, CE report by SGS (EN 300 328 V2.2.2, EN 301 489-1 V2.2.3, -17 V3.3.1), MIC, KC, SRRC, NCC, RCM; DigiKey USD 4.30 at 1 pc.
  • Alternatives reviewed: Raytac AN54LQ-P15 (QFN inside, 9.5 x 13.7 mm, single-row pads, same certificates, USD 4.10) is a drop-in alternative; Ebyte E73-2G4M54LP(15) (12 x 17.2 mm, both crystals and inductor inside) has no module-level certificates as of 2026-10 and was set aside.
  • Another session has uncommitted edits in governance/product-plan.md (Air Hub rows); the Air row edit must be a one-line change that does not touch those hunks.

Proposal

章节标题：“Proposal”
  1. P05-air.md -> R0.10, updated 2026-10-24:
    • §1: first-version hardware is the Raytac AN54LV-P15 certified module (nRF54L15 inside: PCB antenna, 32 MHz crystal, RF match, DECD capacitor); the chip-down nRF54L15 QFN48 design is the cost-down variant with the same circuit, firmware platform and security implementation; "没有首版备选 SoC" stays.
    • §2 row 电子平台: "BLE 版：Raytac AN54LV-P15 模组（nRF54L15 + NFC-A）首版；芯片级 nRF54L15（QFN48）为降本 变体（设计附录 §2.1）".
    • §7: module-based end product path: EN 301 489-1/-17 on the whole product, EN 300 328 by reference to the module report (manufacturer decision, EG 203 367 delta analysis), EN 62368-1 / 62479 / 18031 unchanged; US/CA: FCC/ISED modular grant, Part 15B on the end product, label "Contains FCC ID: SH6AN54LV"; the chip-down variant needs the full radio test set.
    • §8: AIR-O-03 adds module certificate copies, Raytac layout review and the AN54LQ-P15 fallback; new AIR-O-15 "芯片级降本变体切换条件：量产数量 / 单价门槛与整机射频认证预算，D1 决定".
    • §9 change-record row.
  2. P05-air-design.md -> R0.8:
    • §2.1 title "首版锁定：Raytac AN54LV-P15 模组（nRF54L15）"; new first row 模组 with the facts above; row MCU + BLE kept as the SoC facts inside the module; row 替代形态 becomes 降本变体 (chip-down QFN48 per Nordic circuit configuration 1, switch condition AIR-O-15, chip-build schematic and PCB exist on the same 70 x 70 mm outline); one row for the alternatives reviewed (AN54LQ-P15, Ebyte E73).
    • §3: module block diagram; peripheral table rows 时钟 (32.768 kHz on host, 32 MHz inside the module), 稳压 (4.7 uH on host between DCC and DECD, LDO mode if absent), 2.4 GHz 天线 (module PCB antenna at the board edge, 5.0 x 2.9 mm no-copper area on all layers, ground on three sides with vias; chip-down keeps the inverted-F), NFC unchanged.
    • §5: RF row for the module build (keep-out, Raytac layout review, production RF test in a shielded box); 按键 / 灯光 rows note the module GPIO assignment (P1.06/P1.10/P1.11/P1.12, P2.02/P2.03) and the reason; 时钟 row updated.
    • §8 change-record row.
  3. P05-air-guide.md -> R0.5: §2 RF work package delivers the module certificate set and the Raytac layout-review record plus the in-enclosure tuning report; §5 EOL replaces the 32 MHz crystal check with module communication; §6 D0 demonstrates the AN54LV-P15 board; §7 quotes list module procurement and a separate chip-down cost-down quote; §8 change-record row.
  4. air/index.md line 15, governance/product-plan.md line 184 (one line), governance/compliance-matrix.md Switch · Air row (one clause: first version uses a certified module and references its reports): wording aligned.
  5. docs/changelog.md entry; task and plan closed.

Risks

章节标题：“Risks”
  • Firmware: the module build's key and LED pins differ from the chip build; the spec text must say the device tree differs per board so nobody assumes pin compatibility.
  • Certification wording: the module reports cover the module, not the product; the spec must keep the manufacturer responsibility for the whole product (RED DoC) explicit.
  • product-plan.md is being edited by another session; a merge conflict is possible if both touch the same hunk.

Scope

章节标题：“Scope”

Documentation only, 6 files plus changelog, task and plan: bizplan/product/switch/air/P05-air.md, P05-air-design.md, P05-air-guide.md, index.md; bizplan/governance/product-plan.md (one line); bizplan/governance/compliance-matrix.md (one clause); docs/changelog.md. No hardware or code changes.

Alternatives

章节标题：“Alternatives”
  • Record the module only as the "首批" build and keep the chip-down design as the formal first version: rejected by the owner's instruction.
  • Choose Raytac AN54LQ-P15 instead (single-row pads, keeps the chip-build pin map): kept as the documented fallback, not the baseline, because the AN54LV-P15 board already exists and passes DRC.
