背景

GitHub Discussion #1794:用户询问 ZERO 3W 是否支持 5G 112 信道。

内部通过 BOM + 模块 datasheet 核实后确认 ZERO 3 系列存在硬件版本差异:

  • 早期版本(AP6212 模块)仅支持 2.4GHz(802.11 b/g/n)+ BT 4.0,不支持 5GHz;
  • 当前在售版本(V1.12I)已换用双频 Wi-Fi 6 模块(BL-M8800DS2 / FCS960KAAMD),硬件支持 2.4/5GHz + BT 5.4。

修改内容

  1. README 无线规格表(中/英):Wi-Fi 6 (802.11 b/g/n) BT 5.0Wi-Fi 6 (802.11 a/b/g/n/ac/ax) BT 5.4 with BLE
    • 原表述自相矛盾(Wi-Fi 6 = 802.11ax,不是 b/g/n),且与当前 V1.12I 模块规格不符。
  2. FAQ Q9(中/英):补充硬件版本差异说明——早期 AP6212 仅 2.4GHz;当前 V1.12I 双频 Wi-Fi 6 模块;5GHz 具体信道(如 112)可用性取决于驱动/固件/监管域配置,需实测确认。

影响范围

仅 docs/zero/zero3 页面(README + faq),中英双语同步修改。

关联

- README wireless spec: Wi-Fi 6 (802.11 a/b/g/n/ac/ax) BT 5.4 with BLE
  (previous "Wi-Fi 6 (802.11 b/g/n) BT 5.0" was self-contradictory and
  did not match the current V1.12I dual-band module)
- FAQ Q9: note hardware version differences - early AP6212 modules are
  2.4GHz only (BT 4.0); current V1.12I uses dual-band Wi-Fi 6 module
  (2.4/5GHz, BT 5.4); specific 5GHz channel (e.g. ch112) availability
  depends on driver/firmware/regulatory domain

Triggered by GitHub discussion radxa-docs#1794 (ZERO 3W 5G channel 112 question),
confirmed internally via BOM + module datasheets.
