CatSniffer is an original multiprotocol, and multiband board made for sniffing, communicating, and attacking IoT (Internet of Things) devices.

It was designed as a highly portable USB stick that integrates the new chips TI CC1352, Semtech SX1262, Microchip SAMD21E17 V2 or previous, and RP2040 V3 or later.

This board is a Swiss army knife for IoT security researchers, developers, and enthusiasts.

The board can be used with different types of software, including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even write your own software for your specific needs.

CatSniffer Can Operate At Three Different Frequencies:

  • LoRa
  • Sub-1 GHz
  • 2.4 GHz

This work was inspired by our friend’s work, Michael Ossmann, as a tribute to his outstanding job in Greatscott Gadgets, making devices like the YardStick, GreatFET, HackRF, and Ubertooth.

Protocols

  • Thread
  • Zigbee
  • Bluetooth 5 Low Energy (BLE)
  • IEEE 802.15.4g
  • 6LoWPAN (IPv6 over low-power Wireless Personal Area Networks)
  • Sub-1 GHz and patented systems
  • LoRa/LoRaWAN

Features

  • “The SimpleLinkTM CC1352P1F3RGZ device is a multiprotocol and multi-band Sub-1 GHz and 2.4 GHz wireless microcontroller (MCU) supporting Thread, Zigbee®, Bluetooth® 5.2 Low Energy, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), MIOTY®, Wi-SUN®, and proprietary systems”.
  • CatSniffer uses Microchip SAMD21E17 (V2 or previous) and RP2040 (V3 or later) as a USB-UART bridge to communicate with the CC1352 chip; it’s not necessary for a manual driver installation (exceptions could exist).
  • Compatible OS: Windows and Linux
  • Auto-program through the bootloader from TI CC (as long as it’s not disabled in the code).
  • There is no need for an external programmer, and it can be debugged with cJTAG through the default pin.
  • Antenna SMA port for an Antenna of your choice
  • LEDs for general-purpose
  • Reset button for RP2040, SAMD21, and CC1352; Boot of CC1352; and one more for general purpose.
