How to Use
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.
