Description
The Hackitsune 400MHz RF Expansion Module for Flipper Zero is a high-performance Sub-GHz add-on designed to extend the transmission range, signal stability, and overall RF capability of your device.
Built around the E07-400M10S RF module, this expansion provides enhanced performance across the 400 MHz Sub-GHz band, enabling stronger and more reliable signal interaction compared to the internal Flipper radio. This makes it particularly useful for RF research, protocol testing, and signal analysis in environments where increased range or signal clarity is required.
The module is designed to integrate with the Hackitsune SPI & Serial Adapter Module, providing a clean and stable interface to the Flipper Zero while maintaining flexibility for use in other DIY projects. Its compact form factor and external antenna support ensure optimal performance in field and lab environments.
Technical Requirements
- Flipper Zero (not included)
- Hackitsune SPI & Serial Adapter Module (required for Flipper use, sold separately)
- Compatible Sub-GHz firmware or applications
- External antenna connected before operation
Frequency Coverage
Based on the E07-400M10S module, typical supported frequency range is approximately 410 MHz – 525 MHz, depending on configuration and firmware.
How to Use
- Connect the module to the SPI & Serial Adapter (sold separately)
- Attach the assembly to the Flipper Zero GPIO. (ensure the GPIO 5V power is enabled)
- Connect a compatible antenna.
- Launch Sub-GHz applications on the Flipper.
Important Usage Notes
- Always connect an antenna before transmitting
- Operating without an antenna may damage the RF module
- Ensure correct frequency configuration before transmission, this module works best at 410 MHz – 525 MHz, pushing beyond these frequencies can damage the module
