This multi-functional board integrates four critical modules into a single compact unit, including a 433 MHz RF module, an ESP32S2 Predator Wi-Fi module, a GPS module, and a 2.8-inch display screen. Ideal for security enthusiasts, IoT developers, and wireless experimenters, this expansion board allows you to explore RF communication, GPS tracking, and advanced Wi-Fi testing in one convenient accessory.

All-in-One Expansion for Flipper Zero

This expansion board is specifically engineered to complement Flipper Zero, providing an all-in-one solution for wireless research and experimentation. Users can toggle between modules for a seamless experience: the 433 MHz RF module enables sub-GHz signal testing, the ESP32S2 Predator module allows Wi-Fi analysis and security research, the GPS module provides real-time location data, and the 2.8-inch screen offers a dedicated interface for quick visual feedback. This integration allows Flipper Zero to perform multiple tasks simultaneously without additional hardware clutter.

433 MHz RF Module

The 433 MHz RF module is perfect for sub-GHz testing and interacting with wireless devices, including remote controls, smart home devices, and IoT gadgets. Easily accessible through the Flipper Zero sub-GHz menu, this module supports a variety of modulation formats and can be used for capturing, analyzing, and replaying signals. Its 3 dBi antenna ensures reliable transmission and reception for accurate testing.

ESP32S2 Predator Module

The ESP32S2 Predator module is a powerful Wi-Fi testing module integrated into the board. This module can be accessed through the Flipper Zero GPIO menu and is compatible with the Wi-Fi Predator functions of the Flipper Zero app. Designed with advanced TVS protection on signal pins, the ESP32S2 module provides a safe and reliable environment for wireless research, enabling users to scan, test, and experiment with networks in real-time.

GPS Module

The GPS module provides precise location tracking and supports shared power between Flipper Zero and the 2.8-inch Predator screen. Users can select the GPS module to work with either the Predator module or Flipper Zero itself, offering flexibility for mapping, geolocation-based experiments, and navigation tasks. The 20 dBi antenna ensures strong satellite connectivity and accurate positioning.

2.8-Inch Display Screen

The integrated 2.8-inch display provides a dedicated interface for the expansion board, allowing users to monitor signals, access menu options, and interact with Flipper Zero features without switching devices. It retains all functions of the Predator screen version and works seamlessly with additional modules, such as Little Dolphin, for enhanced versatility.

Seamless Integration and Easy Control

The 4-in-1 expansion board is designed for easy installation and intuitive operation. Equipped with boot buttons for the ESP32 Predator and S2 modules, a GPS power switch, and multiple burning ports, users can quickly access and configure each module. The compact design keeps the board lightweight while providing robust performance. With a built-in 800 mAh battery, the board supports extended use during testing and field experiments.
