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 -- GND
TXD -- MCU.RX (signal direction: MCU.RX RXD -- MCU.TX (signal direction: MCU.TX > FT232 > PC.RX)
RTS -- MCU.CTS (signal direction: MCU.CTS CTS -- MCU.RTS (signal direction: MCU.RTS > FT232 > PC.CTS)
