Board Layout and Functional Regions
Diagram illustrating the functional regions of the RF-BT03 development board.
| No. | Function Region | Description |
|---|---|---|
| ① | Module extension area | Supports various RF-star SMT modules (e.g., CC2642R, CC2652R, CC2652R7, CC2652P, CC2652P7, CC1352R, CC1352P, CC1352P7). |
| ② | Pin output area | All module pins are exposed for convenient testing. Refer to the Pin Diagram Description for details. |
| ③ | UART to USB area | Includes CTS, RTS, TXD, and RXD pins of the CP2102 (red box in silkscreen). Green box pins (10, 3, 6, 7) correspond to serial numbers. If module firmware UART pins match, use jumpers. Otherwise, use Dupont wires to connect CP2102 to the module's defined pins. Can also function as a USB to TTL tool with a TYPE-C data cable. |
| ④ | Power supply area | Provides 3.3 V / 5 V power supply. |
| ⑤ | Reset area | Supplies the reset signal to the module. |
| ⑦ | Power supply area | Provides 3.3 V and 5 V power supply. |
Power Supply
The board operates with a power supply of either 3.3 V or 5 V. Ensure your power source matches these specifications.
3. Operating Instructions
This section details how to use the RF-BT03 development board for testing and debugging your RF-star modules.
Connecting for Debugging (USB-to-UART)
- Connect the Module: Ensure your RF-star SMT module (e.g., CC2652P) is correctly inserted into the module extension area (①).
- Power On: Connect a 3.3V or 5V power supply to the power supply area (④/⑦) or via the USB Type-C port.
- UART Connection:
- Identify the CTS, RTS, TXD, and RXD pins of the integrated CP2102 in the UART to USB area (③). These are typically marked in red on the silkscreen.
- Identify the corresponding serial number pins (10, 3, 6, 7) marked in green on the silkscreen.
- If the UART pins defined by your module's firmware (e.g., P10, P03, P06, P01 for CC26X2 transparent transmission firmware) are consistent with pins 10, 3, 6, and 7, you can short-circuit them directly using jumpers.
- If the module's firmware pins are inconsistent, use Dupont wires to connect the CP2102's CTS, RTS, TXD, RXD to the correct pins on your module as defined by its firmware.
- USB Connection: Connect the board to your computer using a TYPE-C data cable. The board will be recognized as a USB-to-TTL tool, allowing serial communication with the module for debugging and programming.
- Reset Function: The reset area (⑤) allows you to supply a reset signal to the module, which can be useful during debugging or firmware updates.

7. Troubleshooting
This section provides solutions to common issues you might encounter with the RF-BT03 development board.
Common Issues & Solutions
- Module Not Detected / No Communication:
- Verify Module Installation: Ensure the RF-star SMT module is correctly and securely seated in the module extension area.
- Check Power Supply: Confirm that the board is receiving the correct voltage (3.3 V or 5 V) and that the power connections are secure.
- UART Pin Consistency: If you are experiencing issues with serial communication, double-check the consistency between the module's firmware-defined UART pins and the CP2102 pins. If inconsistent, ensure you have used Dupont wires to correctly connect them.
- USB Cable: Try a different TYPE-C data cable to rule out cable issues.
- Board Not Powering On:
- Power Source: Ensure your power adapter or USB port is functional and providing the specified voltage.
- Physical Damage: Inspect the board for any visible physical damage or loose components.
User Tips
- Module Inclusion: The RF-BT03 development board is designed to integrate RF-star SMT modules. Please note that the specific CC2652P module may need to be acquired separately or as part of a specific kit, as the board itself is a test platform for these modules. Always verify the contents of your package.
- Firmware Compatibility: When using the UART-to-USB functionality, be mindful of the UART pin definitions in your module's firmware. Adjust connections with jumpers or Dupont wires as needed for proper communication.
