How to Use

Please also see the product Wiki

In the case of working with a MCU:

  • VCCIO: 3.3V or 5V output (the module is powered from USB, onboard jumper should be shorted to 3.3V or 5V)
  • GND: connects to GND
  • TXD: connects to MCU.RX (signal direction: MCU.RX << CP2102 << PC.TX)
  • RXD: connects to MCU.TX (signal direction: MCU.TX >> CP2102 >> PC.RX)
  • RTS: connects to MCU.CTS (signal direction: MCU.CTS << CP2102 << PC.RTS)
  • CTS: connects to MCU.RTS (signal direction: MCU.RTS >> CP2102 >> PC.CTS)

Note: VCP examples and USBXpress driver program library are provided.
