How to make an external CC1101 for the Flipper Zero.

How to Make an External CC1101 Module for Flipper Zero

Materials Needed:

• CC1101 module
• 5V to 3.3V converter
• Header pins
• Circuit board
• Soldering iron
• Wire stripper
• Silicone wire
• Glue
• LED
• Screwdriver or tweezers
• Prototype board
• Spacers

Step 1: Prepare the CC1101 Module

1. Cut off the unnecessary parts from the CC1101 module, leaving only the essential components.
2. Tidy up the module by cutting and cleaning any excess material.
3. Remove any black plastic covering the module to expose the pins.

Step 2: Solder Header Pins

1. Solder header pins onto the CC1101 module. Use 1 to 8 pins as needed.
2. Align the header pins towards your body and solder them onto the module, ensuring a secure connection.
3. Solder the opposite side of the header pins as well as the in-between pins.

Step 3: Connect the Converter

1. Connect the 5V to 3.3V converter to the CC1101 module by soldering the wires to the corresponding pins on both components.
2. Ensure proper connections by following the pin mapping instructions provided in the video.

Step 4: Attach the LED Indicator

1. Connect an LED indicator to the module to show when it is powered on.
2. Trim the LED pins and solder them onto the module for the indicator light.

Step 5: Assemble the Module

1. Place spacers on the prototype board to create space between the module and the board.
2. Carefully align the CC1101 module with the board, ensuring all wires are correctly positioned.
3. Secure the module in place by soldering the pins onto the board.
4. Use additional spacers to maintain the distance between the module and the board.

Step 6: Test the Module

1. Power on the module and check if the LED indicator lights up.
2. Verify the connections and functionality of the CC1101 module using the Flipper Zero device.
3. Test the module with the desired radio settings to ensure proper communication.

Step 7: Optional SMD Component (Surface Mount Device)

1. If desired, add an SMD component for additional functionality.
2. Ensure proper polarity for the SMD component and solder it onto the module.

Step 8: Finalize the Module

1. Check all connections and solder joints for any loose connections.
2. Attach a case or cover to protect the module and provide a finished look.
3. Enjoy your newly created external CC1101 module for the Flipper Zero device.

By following these step-by-step instructions, you can successfully create an external CC1101 module for your Flipper Zero device.
