Safety researcher Joel Serna has launched a brand new variant of his Evil Crow RF sub-gigahertz software-defined radio (SDR) board geared toward “professionals and cybersecurity lovers,” providing microSD logging and a brand new 2.4GHz radio module for expanded spectrum protection.
Serna launched the unique Evil Crow RF penetration testing device final yr, pairing an Espressif ESP32 microcontroller with two of Texas Devices’ in style CC1101 sub-gigahertz radio modules. At its coronary heart, the Evil Crow RF V2 is similar gadgets — however with just a few helpful upgrades.

The most important change is within the addition of a Nordic Semiconductor nRF2401L module, which provides 2.4GHz help to the gadget’s current 300MHz-348MHz, 387MHz-464MHz, and 779MHz-928MHz protection. Native logging is supported via a brand new microSD slot, with the up to date firmware storing each internet server and radio logs on an inserted card by default.
One other main improve is the inclusion of a battery connector, making it simpler to make use of the Evil Crow RF on-the-go with the addition of an non-obligatory lithium-polymer battery. The 2 CC1101 modules, in the meantime, stay independently configurable and include SMA connectors to be used with exterior antennas.
“Evil Crow RF V2 permits the next assaults,” Serna writes of the brand new variant: “Sign receiver; Sign transmitter; Replay assault; URH parse; Mousejacking; [and more].” The firmware, which comes pre-flashed to the gadget, is permissively-licensed open supply and gives an internet interface for ease of management.
The board is obtainable on the market by way of the BLE Beacon Retailer on AliExpress for $43, with restricted portions now out there and extra models to be added all through the week. The firmware supply code, in the meantime, is obtainable on Serna’s GitHub repository beneath the Artistic Commons Attribution 4.0 license.
