Flipper GPIO Modules

Description The Hackitsune ESP32-C5 Dual-Band WiFi Expansion Module for Flipper Zero is an advanced GPIO add-on designed to extend your device with next-generation dual-band wireless research capabilities and modular hardware expansion. Building on the same flexible design as the ESP32-S3 module, the ESP32-C5 introduces 2.4GHz and 5GHz WiFi support, along with WiFi 6 (802.11ax) capabilities, enabling more advanced wireless experimentation and broader protocol coverage. This allows researchers to work across both traditional and modern wireless environments using a single compact module. The Hackitsune ESP32-C5 module also features an upgraded power architecture specifically designed to improve stability and RF performance when operating advanced dual-band wireless hardware. The design incorporates ferrite-bead filtered and separated power rails to isolate sensitive RF circuitry, ESP core power, and expansion interfaces from electrical noise generated by high-frequency wireless activity and external modules. This enhanced filtering approach is particularly important for ESP32-C5 based devices due to the increased complexity of simultaneous 2.4GHz, 5GHz, WiFi 6, and future 802.15.4 operations. High-frequency RF activity and rapid current transients can introduce switching noise, voltage ripple, and interference into shared power rails. By using dedicated filtered rails with ferrite isolation and local decoupling, the module achieves improved wireless stability, cleaner signal performance, reduced interference between peripherals, and greater reliability when using external SPI expansion hardware. In addition to WiFi, the ESP32-C5 platform supports emerging and low-power wireless protocols such as Zigbee (802.15.4) and Thread, providing future potential for expanded firmware support and research into IoT communication ecosystems. The module ships with ESPMarauder firmware pre-installed, making it ready for immediate use while remaining flexible for future firmware development. Like its ESP32-S3 counterpart, the module includes integrated SPI expansion contacts, allowing connection of additional Hackitsune SPI modules (400Mhz, NRF24) and other embedded tools. (Flipper Zero not included.)

The Hackitsune High-Power IR Blaster Module for Flipper Zero is a GPIO expansion designed to significantly extend the infrared transmission capabilities of your device. While the Flipper Zero includes a built-in IR transmitter, its range and output power are limited for longer-distance IR applications. This module overcomes those limitations by integrating 15 high-power IR LEDs, delivering a dramatically stronger and more focused infrared signal. The result is improved range, better signal penetration and performance in real-world environments. Housed in a sleek form factor that mounts cleanly to the top of your Flipper Zero, this module is ideal for IR research, signal testing, and universal remote functionality. (Flipper Zero not included.) Technical Requirements Flipper Zero (not included) 5V GPIO power must be enabled Depending on your firmware the IR app may detect the external IT module and automatically enable 5v (this has ben tested and works on Momentum firmware) Why 5V Power is Required This module is designed to operate from the Flipper’s 5V GPIO rail to support the current demands of multiple high-power IR LEDs. Sufficient current to drive 15 high-power IR LEDs (the flipper zero 5v rail supports up to 1A) Stable output for consistent IR transmission Improved signal strength and range We designed the board to avoid using the flipper's 3.3V rail as this may result in insufficient power output, voltage instability under load, and SD card data corruption. How to Use Attach the module to the Flipper Zero GPIO header. Enable 5V GPIO power in Flipper settings. Select or load an IR signal via the Flipper interface. Transmit using the IR application.

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.
