Pingequa Flipper Zero 2-in-1 RF Devboard NRF24 + CC1101 Wireless Module Instruction Manual

1. Introduction and Overview

This document provides comprehensive instructions for the Pingequa Flipper Zero 2-in-1 RF Devboard, an ultra-compact, high-performance wireless module designed for the Flipper Zero GPIO interface. It combines both nRF24L01P (2.4GHz) and CC1101 (433MHz) chips on a single board, offering auto-switching logic without requiring manual toggling or module replacement.

The module is optimized for stable performance, low power consumption, and long-range, low-noise communication, making it suitable for RF research, testing, and educational development projects.

2. What's in the Box

• 1 × NRF24 + CC1101 2-in-1 Module
• 2 × External Antennas (2.4GHz & 433MHz)
• 1 × 3D Printed Case
• 1 × User Guide

3. Firmware Requirements

This module is specifically optimized for Momentum Firmware. Using official Flipper Zero firmware or other forks without GPIO remapping support will result in the hardware not being detected or functioning correctly.

4. Setup and Installation

Follow these steps to properly configure your Pingequa 2-in-1 RF Devboard with your Flipper Zero:

1. Attach the 2-in-1 board to your Flipper Zero's GPIO pins.
2. Open the Momentum menu on your Flipper Zero.
3. Navigate to: Start → Protocols → GPIO Pins.
4. Locate the NRF24 SPI setting and change it to Extra 7. (The CC1101 is controlled via Pin 4).
5. Save the settings.

Your Flipper Zero is now configured to recognize and utilize both the NRF24 and CC1101 modules.

5. Operating Instructions

Once configured, you can switch between NRF24 and Sub-GHz functions directly through the Flipper Zero application interface. The auto-switching logic ensures seamless operation without manual intervention.

Ensure that any applications you use with the module support custom GPIO/SPI settings, as legacy apps with hardcoded pin definitions may not function correctly with this optimized setup.

7. Maintenance

To ensure the longevity and optimal performance of your 2-in-1 RF Devboard, follow these maintenance guidelines:

• Keep the module clean and dry. Avoid exposure to moisture or extreme temperatures.
• Handle the module with care to prevent damage to the GPIO pins or antenna connectors.
• Store the module in its 3D printed protective case when not in use to prevent physical damage.

8. Troubleshooting

If you encounter issues with your 2-in-1 RF Devboard, consider the following:

• Module Not Detected: Ensure you are running Momentum Firmware on your Flipper Zero. Verify that the NRF24 SPI setting is changed to "Extra 7" in the GPIO Pins protocol settings.
• Application Incompatibility: Some legacy applications may have hardcoded pin definitions that are not compatible with this module's optimized GPIO mapping. Use applications that support custom GPIO/SPI settings.
• Antenna Connection: Ensure both 2.4GHz and 433MHz external antennas are securely attached to their respective ports for optimal signal performance.
