# 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

Note: GPS is now activated automatically when the switch is set to either ESP32 or CC1101 mode. This means GPS functionality (e.g., logging, wardriving) is available during SubGHz operations as well.

# 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 (Feberis Pro v1 - manufactured before 2026): 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.

All Feberis Pro units manufactured from 2026 onwards do not require this workaround - you can start directly in NRF24 mode.

# 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:

For visual learners, a video tutorial is also available here: LINK

  1. Download the latest firmware BIN file from FIRMWARE_LINK and save it to your Flipper Zero's SD card
  2. Make sure the rear switch on FEBERIS PRO is set to ESP32
  3. Connect the FEBERIS PRO module securely to the Flipper Zero's GPIO pins
  4. Navigate to the Applications menu on your Flipper Zero, then to the GPIO folder
  5. Launch the ESP Flasher application (pre-installed on Momentum firmware)
  6. After opening ESP Flasher, select the option "Enter Bootloader"
  7. Next, choose "Manual Flash", then select FirmwareA option. This will prompt you to browse and select the firmware file you previously downloaded to your SD card
  8. Choose Flash Fast option (you do not need to flash the bootloader or partition)
  9. Wait for the flashing process to complete (progress will be displayed on screen)
  10. Once finished, you'll see a success message
  11. Reboot the ESP32 by power cycling the FEBERIS PRO module

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

# Ghost_ESP Firmware

Feberis Pro is officially supported by Ghost_ESP firmware - a feature-rich alternative to Marauder that significantly expands WiFi, BLE, and GPS capabilities.

# What you get with Ghost_ESP on Feberis Pro

WiFi: Deauth, Evil Portal, Beacon Spam, AP/STA scanning, network scanners (ARP, port, SSH), WiFi OUI vendor lookup, WPA3/SAE testing, DHCP starvation, sweep scan across WiFi/BLE/GPS, RSSI tracking for selected APs and stations, drone detection and spoofing.

BLE: Scanning, spam modes, BLE wardrive, AirTag scan and spoof, Flipper finder, GATT/service scan with per-device RSSI.

# How to flash Ghost_ESP

  1. Download the Feberis Pro build from Ghost_ESP GitHub Releases and unpack it to your Flipper Zero's SD card
  2. Connect Feberis Pro to Flipper Zero, set the switch to ESP32
  3. Open the ESP Flasher app → Enter Bootloader → Manual Flash → FirmwareA
  4. Load all three files: firmware, bootloader, partitions
  5. Select Flash Fast and wait for the process to finish
  6. Done - reboot by power cycling the Feberis Pro module
If you have the message 'wrong chip id 0x0002', try to upload all files:

bootloader.bin → to be flashed at address 0x1000
partitions.bin → to be flashed at address 0x8000
boot_app0.bin → to be flashed at address 0xE000

# For Developers

If you're building custom firmware or integrating with the Feberis Pro hardware, here are the key ESP32 GPIO pin assignments:

Function GPIO Pin
GPS TX 4
GPS RX 13
LED 25

These pins are directly connected to the ESP32 module on the Feberis Pro board.

# 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.
