- Clear Status Indicators: TX, RX, and Power LEDs offer easy monitoring of data flow.
 
- Effortless Connections: Accessible pins and included pin headers streamline integration with breadboards and other prototyping tools.
 
Applications:
- Interface with microcontrollers: Program and debug your favorite Arduino, ESP, or other microcontroller boards.
 
- Communicate with sensors: Gather and process data from a wide array of sensors. 
 
- Develop custom electronics: Build unique devices by interfacing USB with TTL-level components.
 
Pinouts
- 
VCCIO ↔ 3.3V or 5V output (the module is powered from USB, onboard jumper should be shorted to 3.3V or 5V)
 
- 
GND ↔ GND
 
- 
TX ↔ MCU.RX (signal direction: MCU.RX << FT232 << PC.TX)
 
- 
RX ↔ 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)

FT232 devices offer two driver options:
- 
VCP (Virtual COM Port): Ideal for simple projects where you want your device to interact like a standard serial device.
 
- 
D2XX: Offers more control and flexibility but requires programming using API functions. Choose this if you need advanced features.
