- LED
- 一个红色的电源LED和一个绿色的状态LED
- USB Type-C接口
- 一个全功能USB-C接口,支持DP,支持USB2.0和USB3.0数据传输,可向外输出5V/2A电源,但不可外接电源给板子供电。支持DRP和安卓ADB调试。因为USB3.0模式下不支持ADB,所以,当使用ADB功能时,请连接到PC的USB2.0端口,或使用只具备USB2.0功能的数据线连接板子和PC。
- 另外一个USB Type-C 5V_IN接口只有给板子供电的功能,用于不接底板快速测试板子。
- 电源输入
- 支持从金手指和USB Type-C 5V_IN接口给核心板供电,支持5V到20V宽电压输入,推荐12V。我们运行安兔兔测试程序时,测量到的最大功耗是10.8W, 建议按12W设计。
- 设计底板时,建议在电源输入处添加100uF/16V,或100uF/35V电解电容, 以减少电源振铃和提供瞬态电流。
