# Introduction

Designed as a versatile expansion for the Flipper Zero, the FEBERIS PRO module connects directly to the GPIO port, integrating onto a single board two CC1101 modules for Sub-GHz bands (433/868 MHz), an NRF24 module (2.4 GHz), and a powerful ESP32 chip with WiFi support and a precise GPS module. This configuration significantly broadens the Flipper Zero's operational spectrum in radio communication, signal analysis, and geolocation, offering the user a powerful tool in a compact form factor.

# Package Contents

  • FEBERIS PRO module with integrated:
    • 2x CC1101 radio modules (433 MHz and 868 MHz)
    • NRF24 radio module (2.4 GHz)
    • ESP32 microcontroller with WiFi (2.4 GHz)
    • GPS module
    • Status LEDs
    • Configuration switches
  • 4 External antennas:
    • 2x for CC1101 (433 MHz and 868 MHz)
    • 1x for NRF24 (2.4 GHz)
    • 1x for WiFi (2.4 GHz)
  • Protective GPIO cover

# Quick Start Guide

# System Requirements

  • Flipper Zero
  • Optional: Custom Flipper Zero firmware (e.g., Momentum) depending on intended use
  • Required applications based on usage:
    • Marauder for WiFi/Bluetooth operations
    • MouseJack for NRF24 operations
    • SubGhz for CC1101 operations

# First Launch

  1. Install all antennas to the appropriate ports on Feberis Pro (from left to right: 433 MHz, 868 MHz, NRF24, WiFi)
  2. Connect Feberis Pro to Flipper Zero's GPIO port
  3. Select desired operating mode using configuration switches
  4. Launch the corresponding application on Flipper Zero based on selected mode

# Technical Specifications

  • Model: Feberis Pro
  • Interface: GPIO
  • Power Supply: Via Flipper Zero GPIO
  • Operating Temperature: -10°C to 60°C

# Operating Modes

# Configuration Switches

Switch 1 Switch 2 Switch 3 Active Module
Up Up Up CC1101 900 MHz
Down Up Up CC1101 430 MHz
Down Down Up NRF24
Down Down Down ESP32 + GPS

# Basic Operations

# SubGHz (CC1101)

# Configuration

  1. Connect Feberis Pro to Flipper Zero
  2. Select the appropriate frequency band (430 MHz or 900 MHz) using configuration switches
  3. Navigate to SubGhz menu
  4. Change source to "External"
  5. Select matching frequency in the SubGhz application based on the previously selected CC1101 module

# Applications

  • Enhanced SubGhz communication range
  • Radio signal analysis
  • Radio remote cloning
  • Radio systems security testing

# WiFi + GPS (ESP32 + GPS)

# Marauder Setup

  1. Ensure switches are set to ESP32 + GPS mode
  2. Launch Marauder app on Flipper Zero
  3. Select desired operation mode:
    • WiFi Scanner
    • Packet Monitor
    • GPS Wardriving
    • WiFi Attack Suite
    • Bluetooth Tools
  4. Configure settings based on your needs:
    • Scan channels
    • Target selection
    • GPS logging options
    • Attack parameters

# MouseJack (NRF24)

# Configuration

  1. Initially set switches to CC1101 mode
  2. Launch MouseJack app on Flipper Zero
  3. Select desired operation mode:
    • Scan for devices
    • Sniff mode
    • Attack mode
  4. After starting the selected operation (e.g., scanning), switch to NRF24 mode using the configuration switches

Important Note: The NRF24 module requires a specific initialization sequence. Always start with CC1101 mode selected, and only switch to NRF24 mode after the MouseJack application operation has been initiated.

# Applications

  • Wireless peripheral security testing
  • Vulnerable device detection
  • Communication protocol analysis
  • Wireless security demonstration

# Advanced Operations

# Firmware Updates

While Marauder comes pre-installed on your Feberis Pro, you might want to update it or install a different firmware. Here's how to do it:

  1. Download the appropriate firmware version from [FIRMWARE_LINK_will_be_available_soon]
  2. Make sure the rear switch on FEBERIS PRO is set to ESP32
  3. Navigate to the ESP Flasher application on your Flipper Zero (install it if not already present)
  4. Connect the FEBERIS PRO module to the Flipper Zero's GPIO pins
  5. Launch the ESP Flasher application
  6. Follow the on-screen instructions to select and flash the firmware
  7. Wait for the flashing process to complete
  8. Reboot the ESP32 (power cycle the FEBERIS PRO module if needed)

Note: You can install any ESP32-compatible firmware as long as it matches the hardware specifications.

# Maintenance and Safety

# Protective Cover

  • When the FEBERIS PRO module is not in use, place the cover on the GPIO pins to prevent damage or contamination.

# Storage

  • Store the module in a cool, dry place away from extreme temperatures or high humidity.

# Operating Conditions

  • Recommended temperature range: –10°C to 60°C.
  • Avoid bending or pressing on the FEBERIS and its connectors.
