The Hackitsune SPI and Serial Adapter Module is engineered to extend the functionality of your Flipper Zero while protecting its most critical component: the SD card. By leveraging the Flipper’s dedicated 5V GPIO rail (enabled via GPIO settings), this module provides a clean, stable power supply and GPIO connectivity to external SPI and Serial peripherals without loading the 3.3V rail that services the SD card. Why does this matter? Many external modules draw inconsistent current or introduce electrical noise that can destabilize the 3V rail, risking SD corruption or unexpected resets. The PowerBridge isolates and stabilizes power delivery, ensuring your expansions run clean while your core system remains protected. Designed for Expansion This adapter acts as a reliable foundation for a growing ecosystem of 3rd party and Hackitsune-compatible modules, including: NRF24 (2.4GHz) boards – for wireless research applications 433MHz & 915MHz RF modules – extended sub-GHz experimentation GPS satellite modules – wardriving and geospatial testing Additional SPI & UART-based modules will be added as the ecosystem expands This module is designed for Hackitsune modules, and can support a range of 3rd party modules available online. Always check the pin configuration of modules before connecting to this adaptor and your flipper as incorrect pin/ power connections can damage modules! Whether you're building out a portable RF toolkit or developing custom GPIO integrations, the PowerBridge ensures your setup remains stable under load.

NRF24 Mouse & Keyboard Module for Flipper Zero Slip this little rascal onto your Flipper and watch "air-gapped" illusions wobble. Built for curious defenders, cheeky pen-testers, and anyone who enjoys proving problems exist before they become disasters. This compact nRF24 module gives your Flipper Zero the muscles to scan for, emulate, and interact with nRF24-based wireless HID dongles, the RF technology wireless keyboards and mice often use. It’s great for lab demos, vulnerability audits, and classroom show-and-tell where you want to turn “maybe vulnerable” into “definitely fixed.” Supported by most Flipper firmwares — we recommend Momentum for the smoothest ride. Keyboard & Mouse Jacking Some older wireless keyboards/mice and their tiny USB dongles trust RF traffic they really shouldn’t. When links accept unauthenticated or poorly authenticated packets, attackers can inject keystrokes or mouse actions remotely. That’s keyboard jacking / mouse jacking: scary-sounding, but exactly the kind of thing you should only test for in a controlled, authorised environment. This module helps you demonstrate the risk so you can fix it. Compatibility & firmware Works with most Flipper Zero firmware branches. Momentum firmware recommended. Check your firmware docs for specific nRF24 HID features. What’s in the box nRF24 RF module (Flipper-compatible form factor. This module can be plugged into the flipper zero, or DIY ESP/ Arduino project using breadboard / jumper cables. We recommend using a flipper adaptor for ease of use.

Despite the size these antennas provide pack 3dBi signal strnegth into a 3cm package. Specifications 433MHz (Frequency): Optimized for devices operating in the UHF band, commonly used for garage door openers, telemetry, IoT sensors, and remote controls. 3dBi (Gain): Amplifies the signal by 3 decibels relative to an isotropic radiator (dBi). This increases range compared to a lower gain antenna. Rubber Antenna (Type): Frequently called a "rubber duck" antenna; flexible, durable, and encased in rubber for indoor/general-purpose use. SMA Male (Connector): Screws directly onto devices with an SMA Female connector (fits Hackitsune 433Mhz Flipper Module and the 400Mhz side of the dual frequency (400-900mhz) flipper module). 3cm (Length): Indicates the physical length, making it ideal for compact applications where space is limited, though efficiency can sometimes be lower than longer alternatives.
