Description
The Seamless Bridge for USB to TTL Projects - Transform your project workflow with the 7Semi FT232 USB UART Board – your essential tool for reliable USB-to-TTL communication.
Simplify the way you interact with microcontrollers, sensors, and other TTL-level devices using the 7Semi FT232 USB UART Board. This compact module features the original FT232RL chip, guaranteeing stable performance and wide-ranging compatibility across Windows, Mac, Linux, and various other operating systems.
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 |
| DTR# | Data terminal is ready for controlling external devices, low active | Output |
| DSR# | Dataset is ready for detecting whether the external device is ready, 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.
