Overview
The Hub by Sacred Labs is a central connectivity board that expands your Flipper Zero's capabilities by integrating CC1101 SubGHz and NRF24L01 modules for seamless GPIO connectivity. This innovative accessory ensures stable and reliable connections while maintaining a compact design.
Key Features
- CC1101 SubGHz: Extended frequency capabilities
- NRF24L01: 2.4GHz wireless testing
- 5V Power: Stable power supply for components
- Compact Design: Seamless Flipper Zero integration
- GPIO Connectivity: Direct connection to Flipper Zero
Important Requirements
You will need unofficial firmware on your Flipper Zero. We use and test devices using Momentum firmware, but you may choose another one that supports the required applications.

Component GuideNRF24 Module
Frequency: 2.4GHz
Primary Use: Wireless mouse/keyboard testing
What is NRF24?
The NRF24 module operates on the 2.4GHz frequency band and is designed to test the security of wireless mice and keyboards that use unencrypted communications.
Using NRF24
Use the [NRF24] Sniffer application to scan for vulnerable wireless mice and keyboards, then use [NRF24] Mouse Jacker to test connections.
Important Limitations
- Only works with vulnerable devices
- Not every wireless mouse/keyboard will work
- Device must use insecure communication protocols
- Modern devices with proper encryption won't be affected
CC1101 Module
Optimal Frequency: 433MHz
Primary Use: Sub-GHz range extension
What is CC1101?
The CC1101 is a sub-GHz transceiver that significantly extends the range and capabilities of your Flipper Zero's built-in Sub-GHz radio. It's designed for the 433MHz frequency band.
Key Benefits
- Extended Range: Much greater transmission/reception distance
- 433MHz Focus: Excellent performance on the most common frequency
Using CC1101
Open SubGHz application → Radio Settings → Change module from "Internal" to "External". The CC1101 module now enhances all SubGHz applications with extended range and better signal quality.
Important Limitations
CC1101 chips perform best on 433MHz due to the enhanced chip and antenna configuration. While other frequencies work, 433MHz provides the best range and signal quality.
Hardware Controls
