Evil Crow RF V2 - Advanced Cybersecurity Testing Tool

Evil Crow RF V2 is a board for working with sub-GHz and 2.4 GHz radio communication: two CC1101 transceivers, an nRF24L01 module and an ESP32 with a web panel over WiFi. You receive, record and replay the signals of your own remotes, sensors and IoT devices on a test bench, with no SDR computer needed.

Two CC1101 and nRF24L01 on one board

The CC1101 chips cover 300-348, 387-464 and 779-928 MHz, the bands used by gate remotes, alarm sensors, weather stations and cheap 433/868 MHz modules. Each of the two modules is configured separately, so one can listen while the other transmits on a different frequency at the same time. The nRF24L01 adds the 2.4 GHz band for analysing the communication of simple wireless devices.

Evil Crow RF V2 web panel

The official firmware runs a browser panel on the ESP32. In RX Config you set the module, modulation (e.g. ASK/OOK), frequency, bandwidth, deviation and data rate, and received data lands in the Log Viewer in raw and corrected form. TX Config sends stored RAW data from the chosen module, Config changes the WiFi network, and the home page shows the firmware version, IP address, CPU temperature and microSD status.

Firmware from the official repository

The board ships with the project's basic firmware. Source code, Arduino IDE build instructions and the panel files for the microSD card are in the Evil Crow RF V2 repository maintained by the project author, Joel Serna. The Discord support link is there too.

Power, microSD card and case

The USB-A plug powers the board from a computer port or a power bank. The web panel needs a microSD card (32 GB or smaller recommended, sold separately) with the HTML files from the repository. Two SMA connectors take antennas for the band you work in. For field use add the Evil Crow RF V2 case with a battery bay.

What to use Evil Crow RF V2 for

Checking your own radio devices: whether a remote can be recorded and replayed, whether a sensor uses rolling code, what a weather station transmits and how often. Transmit only towards your own devices, on a test bench and in line with the radio spectrum regulations of your country.
