Description
Description
The Hackitsune 900MHz RF Expansion Module for Flipper Zero is a high-performance Sub-GHz add-on designed to extend the transmission range, signal stability, and frequency coverage of your device into the higher Sub-GHz bands.
Built around the E07-900M10S RF module, this expansion enables operation across the 855 – 925 MHz range, delivering stronger output power and improved reception sensitivity compared to the onboard Flipper radio. This makes it particularly useful for authorised RF research, protocol analysis, and testing in environments where higher-frequency Sub-GHz bands are commonly used.
The onboard Flipper radio is not designed for reliable transmission in these higher frequency ranges and attempting to operate beyond its intended bands may lead to degraded performance or potential hardware stress. This external module provides a dedicated and safer pathway for working within the 800–900 MHz spectrum.
Designed to integrate with the Hackitsune SPI & Serial Adapter Module, the board provides a stable and modular interface to the Flipper Zero while also remaining compatible with other embedded platforms.
Technical Requirements
- Flipper Zero
- Hackitsune SPI & Serial Adapter Module (required for Flipper use)
- Compatible Sub-GHz firmware or applications
- External antenna connected before operation
Frequency Coverage
Based on the E07-800M10S module supported frequency range is 855 – 925 MHz, depending on configuration and firmware.
How to Use
- Connect the module to the SPI & Serial Adapter.
- Attach the assembly to the Flipper Zero GPIO.
- Connect a compatible antenna.
- Launch Sub-GHz applications on the Flipper.
- Perform authorised signal testing or analysis.
Important Usage Notes
- Always connect an antenna before transmitting - Operating without an antenna may damage the RF module
- Ensure correct frequency configuration before transmission
- Use only in authorised and controlled environments
