- 仓库: ZSWatch/ZSWatch - 固定快照: 1dc5b7049cc49485a34f9fb59762cea9a11dea58
这是我目前找到的、公开可访问的、和 ANNA-B402 / nRF52833 最接近的一套历史硬件参考之一：
- 有 KiCad 工程 - 有 Zephyr 板级定义 - 有导出的原理图 PDF
- ZSWatch v1 的 KiCad 硬件文件明确使用了 u-blox ANNA-B402 - ZSWatch v2 已经迁移到 u-blox NORA-B106
虽然它不是 u-blox 官方参考板，也不是当前仍在维护的主线设计，但对下面这些事情很有参考价值：
- 看公开项目是怎么围绕 ANNA/nRF52833 做板级设计的 - 对照 Zephyr DTS 和真实硬件连接 - 参考显示、SPI、I2C、按键、电池测量这类外围怎么接
