-
The carrier board requires a 12V(compatible with 9-19V) DC power supply. To ensure normal system operation, a power adapter with sufficient current output must be used. Additionally, under high load conditions with an input voltage exceeding 15V, adequate heat dissipation must be provided to prevent overheating.
-
This product includes reverse-polarity protection. Nevertheless, do not connect the power supply in reverse.
- The over-current protection (OCP) threshold for all USB ports is 2.5A. Exceeding this limit will trigger an automatic shutdown of the power output.
- In contrast to the original M.2 2230 interface, the backplane's network interface now features a symmetrical layout.
-
Do not hot-swap the module. Always power off the board before inserting or removing the module. Failure to do so may damage the module and the carrier board. Damage caused by improper operation is not covered under warranty.

部分功能说明
- 启动按钮 (10)：相比于原厂载板，C1902多设置了一个启动按钮，该按钮具有以下功能：
- 系统启动时：按动一次进入关机界面，长按 10 秒强制关机。
- 系统关闭时：按动一次进行开机。
- 40PIN排针 (14)：40Pin GPIO排针中的 5V 输出具有倒灌保护，该 5V 输出最大电流为 0.8A，过流会关断输出，参考定义如下（实际以核心卡为准）。
- 12Pin调试接口 (11) 定义如下：
- 固态硬盘必须使用单面版本，使用双面贴片版本固态硬盘，有可能发生干涉，引起短路。
- 电池接口 (4)：相比于原厂载板，C1901 多设置了一个 RTC 电池连接器，该连接器型号为 MX1.25-2P，电池电压为 3V。使用电池时，请确认好极性，禁止接反电池。
接入电池后，需要进行配置才能启用 RTC 时钟，详情请参考 RTC 说明
