CC1101 433 MHz Sub-GHz Radio Module — open-source extension for Flipper Zero and IoT projects (legal & educational use).

The CC1101 Sub-GHz 433 MHz Module is a compact, open-source add-on designed to expand the radio capabilities of your Flipper Zero or any microcontroller-based IoT project. Ideal for makers, researchers, and developers, it allows for sub-GHz (433 MHz) experimentation with open-source libraries, while remaining focused on legal, educational, and research use.

This module is easy to plug in and offers a standard SPI interface for driving the CC1101 from an ESP32, Arduino, or Flipper Zero (external modules). It is ideal for sensor prototyping, radio analysis in controlled environments, and learning sub-GHz communications.

Getting started — (high level, safe)

1. Solder the headers and connect the module to the SPI port of your controller (3.3 V).

2. Install a compatible CC1101 library (Arduino / PlatformIO / ESP32).

3. Load a basic receive/transmit example provided in the GitHub repository.

4. Test only on authorized frequencies and devices, in your environment (lab) or with explicit consent.
