[FAQ] 使用毫米波传感器的快速入门步骤
使用加电后，NRST灯不亮，且找不到串口，这是板卡问题还是程序安装问题？
上电后NRST灯应该会亮，请看下面文档说明。As soon as the power is provided, the NRST and 5-V LEDs should glow, indicating that the board is powered onhttps://www.ti.com/lit/ug/swru521c/swru521c.pdf
请看一下供电电源是否是A 5-V, > 2.5-A？
我也是看了说明文档，供电电源用的是配套的供电器，转变输出电压5v，电流2.5A
那可能板子有问题了。
