- PH2.0 connectors(USB2.0 I2C, UART, ADC, IR)
- I2C2，I2C3，UART4，UART_U的电平均为3.3V；ADC输入范围为0~1.8V；请直接连接红外接收器对应的三个引脚到IR IN接口(IR1)
- UART_U为USB转的串口

- Microphone
- 3.5mm耳机孔(MIC1)和PH2.0座子(MIC2)是同一路麦克风输入，当插入3.5mm耳机孔后，PH2.0座子的信号被断开。请直接连接麦克风，理论上支持所有类型的麦克风。
- Power Supply
- 底板提供两个电源输入接口，5.5*2.1 DC插座和4Pin PC电源插座，型号是Molex 5566-04A(或兼容)，都是处于开关之前，受开关控制。
- 底板除了有一个电源开关，还提供了一个XH-2A开关引出座子。
- J1是开机模式选择跳针，开路上电自动开机，短接则需要按一下电源按键才能开机。
- 必须使用12V电源供电。因为电源输入放置了一个12V的TVS(型号是SMAJ12A)，所以输入电压不能超过13.3V。理论上支持5V-12V输入，但是考虑到负载，LCD供电等原因，推荐使用12V，以免负载变大时，由于较低电压的DC电源输出电流不足或电源线损耗太大导致不稳定。
- Fan & heatsink
- 请搭配散热片和风扇使用板子。如果风扇不转动，可能是因为CPU温度还不足以触发温控程序输出PWM来驱动风扇。
- 连接器型号: JST GH系列连接器，3Pin，BM03B-GHS-TBT
