The Original FT232RL Onboard is a USB to serial converter module that supports various operating systems, including Mac, Linux, Android, WinCE, Windows 7/8/8.1/10. The module offers 3 power modes: 5V output, 3.3V output, or powered by the target board (3.3V-5V). The module features 3 LEDs: TXD LED, RXD LED, POWER LED.
The TXD, RXD, RTS#, and CTS# pins are connected to the onboard soldered pin headers, while the other pins are accessible via drill holes. Separate pin headers are also provided for easy connection to the user system, with a pitch compatible with breadboards.

The other Pins : accessable on the drill holes (separate pinheaders are also provided for easily connecting to user system, the pitch is compatible with bread boards)

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