Flipper Zero Three-in-One Backpack Module – 5G CC1101 NRF24 Compatible

The Flipper Zero Three-in-One Backpack Module is a versatile and powerful expansion accessory designed to supercharge your Flipper Zero device. Combining three essential wireless modules into a single compact unit, this module supports 5G WiFi, Sub-GHz RF communication, and 2.4GHz NRF24 signal operations. It is ideal for wireless security testing, IoT research, and educational experimentation, providing Flipper Zero users with unmatched functionality and convenience.

Three-in-One Design for Ultimate Efficiency

The Flipper Zero Three-in-One Backpack Module integrates three high-performance modules in a compact form factor: the 5G Sub-GHz BW16 module, the CC1101 Sub-GHz RF module, and the NRF24 2.4GHz RF module. This innovative three-in-one design saves hardware space, reduces the need for frequent module replacements, and allows users to switch between multiple wireless protocols seamlessly. With all three modules built into one backpack, your Flipper Zero becomes an even more versatile tool for wireless communication and security testing.

Module Composition and Core Functions

The three integrated modules each serve unique purposes:

• 5G Sub-GHz Module (BW16): Equipped with the RTL8720DN chip, this module supports both 5G and 2.4G frequencies. It comes pre-flashed with 5G WiFi deauth firmware compatible with Flipper Zero, enabling advanced WiFi testing and deauthentication operations.

• CC1101 Module: A high-performance Sub-GHz RF chip covering 300–928MHz with multiple modulation modes such as ASK, OOK, and FSK. Perfect for interacting with IoT devices, smart home systems, and wireless access controls.

• NRF24 Module: A 2.4GHz RF module commonly used for wireless keyboard and mouse signal sniffing and replay. Ideal for analyzing and testing everyday wireless peripherals.

This combination of modules ensures comprehensive wireless coverage, from 2.4GHz to 5G, giving users a wide range of research and testing capabilities.

Application Scenarios

The Flipper Zero Three-in-One Backpack Module is designed for a variety of practical uses:

• Wireless Security Testing: Sniff, replay, and analyze access control and remote control signals to assess vulnerabilities in wireless communication systems.

• IoT Research and Development: Interact with smart devices like light bulbs, sensors, and other Sub-GHz or 2.4GHz-enabled IoT gadgets.

• Educational Experiments: Explore and learn wireless communication protocols, including 5.8G, 2.4G, and BLE, making it ideal for students and hobbyists interested in electronics and RF systems.

Open-Source Support and Flexibility

One of the standout features of this module is its compatibility with Flipper Zero’s open-source ecosystem. Firmware extensions and custom configurations allow advanced users to modify frequency bands, adjust signal parameters, or implement custom functions. GPIO interfaces are allocated efficiently for each module: BW16 uses GPIO TX/RX, CC1101 uses GPIO A4, and NRF24 uses GPIO A7. Users can enable modules independently, ensuring optimal resource allocation and functionality for each scenario.

Advantages of the Three-in-One Module

The Flipper Zero Three-in-One Backpack Module offers several key benefits:

• Compact design saves hardware space and reduces clutter.

• Seamless integration with Flipper Zero for enhanced wireless capabilities.

• Open-source community support for custom firmware, experimental applications, and advanced features.

• Multi-protocol support covering 5G, Sub-GHz, and 2.4GHz frequencies.

• Ideal for educational experimentation, IoT development, and wireless security research.

Technical Considerations and Compliance

It is important to note that some frequency bands used by the module must comply with local radio regulations. Users looking to reflash the BW16 module should press and hold the boot button while powering on the device and flash it via TX/RX 3.3 GND. Additionally, some advanced features require a basic understanding of RF technology, such as signal decoding, frequency selection, and firmware compilation.
