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.
