    测试情况,就接4根线,电源+ 电源- ,串口Tx,串口Rx ,其他悬空!
    请问如何处理?

    @leixingmin 检查电源,供电电流不足。



  • 你好,这个需要多大电流?
    我用的 sm1117 5v转 3.3芯片


  • administrators

    @leixingmin 正常的1117电路可以带动
    检查如下:

    1. 是否电源线太细?
    2. 1117输入电流不足、电压过低?
    3. 去藕不足?


  • 问题找到了,串口TX0 RX0 信号,直接引出的,有干扰,选择的usb-ttl数据线质量一般,换了一个帝特的USB转换的头,一切正常了。 建议在做板子时要上拉稳定信号;
