The 7Semi FT232 USB UART Board (micro) is a compact module designed for seamless USB-to-TTL communication. It features the original FT232RL chip, ensuring stable performance and broad compatibility across Windows, Mac, and Linux operating systems. The board offers flexible power options, allowing selection between 5V and 3.3V outputs, and includes status LEDs for easy monitoring of data flow. Its breadboard-friendly design facilitates straightforward integration into various projects.
Key Features:
- Genuine FT232RL Chip: Provides a trustworthy foundation for your projects.
- Multi-OS Support: Eliminates compatibility concerns across popular platforms.
- Flexible Power: Select between 5V or 3.3V output, or conveniently power the module directly from your target board (3.3V-5V).
- 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)
Function
| Pin | Function | Input/Output |
| VCCIO | 5V or 3.3V available for external devices (via jumper cap) | - |
| GND | Ground | - |
| TX | Serial data transmit pin, connect to MCU.RX | Output |
| RX | Serial data receive pin, connect to MCU.TX | Input |
| RTS# | Request to send, connected to MCU.CTS | Output |
| CTS# | Clear to send, connected to MCU.RTS. | Input |
| RI# | Ringing indication, used to detect whether the external device is ringing, low active | Input |
| DCD# | Data carrier detection, low active | Input |

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.
