3H34N Flipper Zero Board (Three in One – CC1101/NRF24L01/ESP32)

 3H34N Flipper Zero Board (Three in One – CC1101/NRF24L01/ESP32)

I'm thrilled to announce that the PCB for the Flipper Zero board has been successfully completed. This design integrates three modules into a single board.

As you can see, one side of the board houses two modules, while the other side holds one module. On the left, we have the NRF24L01; on the right, the CC1101; and on the back, the ESP32.

The NRF24L01 module is used for mouse jacking and operates on the Bluetooth frequency. Please note that when using Bluetooth, the NRF24L01 conflicts with the CC1101, so it’s necessary to remove the CC1101 from the board, using pin headers.

On the right, we have the CC1101 module, which helps increase the range of reception and transmission of sub-gigahertz radio signals. As you may know, the Flipper Zero already has an internal CC1101 module, but when you want to use sub-gigahertz, you should switch to the external module through the sub-gigahertz settings. You can also connect a custom antenna to extend the range.

On the back is the ESP32. Since the Flipper Zero doesn’t have an internal Wi-Fi chip, this module is essential for certain Wi-Fi attacks and is compatible with the [ESP32] Wi-Fi Marauder application on the Flipper Zero.

Additionally, we’ve included 3-position DIP switches to connect VCC power to each module as needed. This feature helps prevent conflicts and conserves battery life.

Requirements for Board:

NRF24L01+PA+LNA Module

CC1101 Module

ESP32-WROOM-32 - CP2102 Chip - 30pin Module

3 Way 2.54MM DIP switch

2x4 Pins header Female

2x4 Pins header Female

Female Header 2.54mm single row 15 Pin

Female Header 2.54mm single row 15 Pin

Strengths: Simple, affordable, portable module; three-in-one design.

Weaknesses: The NRF24L01 conflicts with the CC1101.

A special thanks to my friends Reza and Pouya for their participation and support throughout this journey.
