KrakenSDR is a phase-coherent software-defined radio with five RTL-SDRs KrakenSDR is a 5-channel, RX-only, software-defined radio (SDR) based on the RTL-SDR and designed for phase-coherent applications and experiments. Phase-coherent SDR opens the door to some very interesting applications, including radio direction finding, passive radar, and beam forming. You can also use KrakenSDR as five separate radios. KrakenSDR is an upgraded version of the previous product, KerberosSDR. It provides a fifth receive channel, automatic phase-coherence synchronization capabilities, bias tees, a new RF design with cleaner spectrum, USB Type-C connectors, a heavy-duty enclosure, upgraded open source DAQ and DSP software, and an upgraded Android app for direction finding. RTL-SDR KrakenSDR makes use of five custom RTL-SDR circuits consisting of R820T2 and RTL2832U chips. The RTL-SDR is a well-known, low-cost software-defined radio (SDR), but throw five units together and using them on the same PC will not make them 'phase coherent;' each one will receive signals at a slightly different phase offset from the others. This makes it difficult or impossible to achieve a high degree of precision when measuring relationships between signals that arrive at different antennas. To achieve phase coherence, KrakenSDR drives all five RTL-SDR radios with a single clock source, and contains internal calibration hardware to allow the phase relationship between channels to be measured precisely and corrected for. Additionally, the overall design of KrakenSDR works to ensure phase stability, with care taken in the areas of heat management, driver configuration, power supply, and external-interference mitigation. Features Five-channel, coherent-capable RTL-SDR, all clocked to a single local oscillator Built-in automatic coherence synchronization hardware Automatic coherence synchronization and management via provided Linux software 24 MHz to 1766 MHz tuning Range (standard R820T2 RTL-SDR range, and possibly higher with hacked drivers) 4.5 V bias tee on each port Core DAQ and DSP software is open source and designed to run on a Raspberry Pi 4 Direction-finding software for Android (free for non-commercial use) Applications Physically locating an unknown transmitter of interest (e.g. illegal or interfering broadcasts, noise transmissions, or just as a curiosity) HAM radio experiments such as radio fox hunts or monitoring repeater abuse Tracking assets, wildlife, or domestic animals outside of network coverage through the use of low power beacons Locating emergency beacons for search-and-rescue teams Locating lost ships via VHF radio Passive radar detection of aircraft, boats, and drones Traffic-density monitoring via passive radar Beamforming Interferometry for radio astronomy Specifications Bandwidth 2.56 MHz RX Channels 5 Frequency Range 24-1766 MHz Radio Tuner 5x R820T2 Radio ADC 5x RTL2832U ADC Bit Depth 8-bits Oscillator Stability 1 PPM Typical Power Consumption 5 V/2.2 A (11 W) Enclosure Type Heavy-duty CNC Aluminum Dimensions 177 x 112.3 x 25.9 mm Weight 560 g Included 1x KrakenSDR (fully assembled and installed) with Aluminum enclosure 1x Manual Required USB Type-C cable 5 V/2.4 A USB-C power supply Antennas Raspberry Pi 4 (for computing) Android phone/tablet with mobile-hotspot capabilities (with direction finding) Downloads Wiki Android App

Multi-tool for Building, Analyzing, and Hacking USB Devices Cynthion is an all-in-one tool for building, testing, monitoring, and experimenting with USB devices. Built around a unique FPGA-based architecture, Cynthion’s digital hardware can be fully customized to suit the application at hand. As a result, it can act as a no-compromise High-Speed USB protocol analyzer, a USB research multi-tool, or a USB development platform. Out-of-the-box, Cynthion acts as a USB protocol analyzer capable of capturing and analyzing traffic between a host and any Low-, Full-, or High-Speed ("USB 2.0") USB device. It works seamlessly with the open-source analysis software Packetry. Combined with the LUNA gateware and Facedancer libraries, Cynthion becomes a versatile USB research and development tool. Facedancer makes it quick and easy to create or experiment with real USB devices—not just emulations—even if you don’t have experience with digital hardware design, HDL, or FPGA architecture! Features Cynthion is a fully reconfigurable test instrument that provides all the hardware, gateware, firmware, and software you need to work with—and, indeed, tob master-USB. Below are a few of the challenges to which you can apply your Cynthion: Protocol analysis for Low-, Full-, and High-speed USB: Cynthion provides everything you need for passive USB monitoring. With the Packetry USB analysis software, Cynthion provides everything you need for passive USB monitoring. Creating your own Low-, Full-, or High-speed USB device: LUNA provides Amaranth gateware that allows you to create USB devices in gateware, firmware, or a combination of the two. Using the Facedancer library, you can create or emulate real USB devices in high-level Python. Meddler-in-the-Middle (MitM) attacks on USB communication: Cynthion hardware can function as a "USB proxy" capable of transparently modifying USB data as it flows between a host and a device. Each board’s three USB-C connections allow for simultaneous, high-speed proxying while maintaining a high-speed connection to the host. As a result, you can proxy a connection with or without the help of a host PC. USB reverse engineering and security research: Cynthion hardware and LUNA gateware represent a purpose-built backend for research tools like Facedancer and USB-fuzzing libraries, thereby simplifying the emulation and rapid prototyping of compliant and non-compliant USB devices. Unlike other USB-emulation solutions, Cynthion-based hardware is dynamically reconfigurable, so it gives you the flexibility to create any endpoint configuration and engage in almost any USB (mis)behavior. Specifications A Lattice Semiconductor LFE5U-12F ECP5 FPGA supported by the yosys+nextpnr open-source FPGA flow Three High-Speed USB interfaces, each connected to a USB3343 PHY capable of operating at up to 480 Mbps.
