产品概述

  • 多种USB转串口主控芯片(CH340、FT232、CP2102)可供选择,速度快,稳定性好。
  • 板载电源指示灯及多种信号指示灯(RX、TX、CTS、RTS),可更方便的检测模块工作状态。
    • 初次上电,电源指示灯常亮,RX和TX灯快闪,RTS灯慢闪。
  • 电源VCC和信号电平(RX、TX、CTS、RTS、DTR、DSR、DCD)均支持5V/3.3V/2.5V/1.8V四种电平切换,适应不同电压的系统。
    • 采用拨码开关选择电压,无需断电操作。
  • 采用芯片转换方案,非三极管方案,低电平为0V(三极管方案由于有导通压降,低电平无法达到0V)
  • 引出CTS、RTS信号管脚,FT232、CP2102版额外引出DTR、DSR、DCD引脚,可以方便的进行硬件流控。
  • USB口带有静电保护和电流保护。
  • 信号接口RX、TX、CTS、RTS口带有电流保护和ESD保护。
  • 波特率支持范围:
    • CH340:50bps ~ 2M bps
    • FT232:300bps ~ 3Mbps
    • CP2102:300bps ~ 1M bps

3. Verify if the module is working properly. Short-circuit the TXD and RXD pins of the module, open theserial port debugging software, , and click "Open Serial Port". Enter any content in the text box, then click the "Send" button. Under normal circumstances, the software will receive and display the same content.
