Great Scott Gadgets – Cybersecurity and Communication Analysis Tools

Great Scott Gadgets develops open-source hardware tools for radio signal analysis, USB and Ethernet communication analysis, and electronic system prototyping. The manufacturer's product range includes HackRF One SDR devices, the YARD Stick One transceiver, Cynthion USB analyzers, the GreatFET One platform, passive Throwing Star LAN Tap interfaces, antennas, and expansion modules. These products are used for authorized security testing, reverse engineering, protocol diagnostics, and embedded systems research. Tools for communication analysis and testing are available in the Cybersecurity category, which includes equipment for evaluating the security of devices and communication infrastructure.

HackRF One and YARD Stick One – Radio Communication Analysis

HackRF One supports receiving and transmitting radio signals in the frequency range from 1 MHz to 6 GHz. It works with SDR software used for spectrum analysis, modulation testing, and wireless system evaluation. The HackRF One Bare Board variant provides the same device functionality without the standard enclosure. YARD Stick One supports digital radio communication below 1 GHz and enables the analysis of selected transmission protocols via USB. Both devices can be used for wireless communication analysis, testing custom RF systems, and researching protocol security. Related solutions are available in the SDR Receivers category.

ANT500 and ANT700 Antennas and Opera Cake Antenna Switch

The Great Scott Gadgets product range includes ANT500 and ANT700 telescopic antennas, designed for use with compatible radio devices, including HackRF One and YARD Stick One. The ANT500 operates from 75 MHz to 1 GHz and features an adjustable length from 20 to 88 cm, while the ANT700 covers 300 MHz to 1.1 GHz with an adjustable length from 9.5 to 24.5 cm. Both antennas have a 50 Ω impedance and an SMA male connector. Opera Cake adds software-controlled antenna and external RF signal path switching to HackRF One, simplifying measurements across different frequency ranges. These accessories complement equipment used for RF analysis and SDR experiments.

Cynthion – USB Protocol Analysis and Security Testing

Cynthion uses an FPGA to capture and analyze communication between USB devices and to develop custom hardware solutions. It works with the open-source Packetry software and the LUNA project, supporting the analysis of USB Low-Speed, Full-Speed, and High-Speed communication, as well as experimentation with USB device functionality. The Cynthion Bare Board variant is also available for applications that do not require the standard enclosure. The platform is suitable for peripheral device diagnostics, protocol analysis, and authorized USB security testing. Related equipment is available in the Cybersecurity category.

GreatFET One – Universal Prototyping and Debugging Platform

GreatFET One features an LPC4330 microcontroller and provides programmable input/output pins alongside SPI, I2C, UART, and JTAG interfaces. The platform supports logic signal analysis, communication with integrated circuits, debugging, and development of custom USB devices. The Daffodil module expands GreatFET One with breadboard connections, simplifying electronic circuit prototyping. A clear acrylic enclosure for GreatFET One is also available, featuring cutouts that provide access to the board's connectors.

Throwing Star LAN Tap – Ethernet Traffic Monitoring

Throwing Star LAN Tap enables passive traffic monitoring on 10/100 Mb/s Ethernet networks. The device is connected between two network components, while dedicated monitoring ports allow traffic to be forwarded to a computer running packet analysis software such as Wireshark or tcpdump. The Throwing Star LAN Tap Kit is supplied as a set of components requiring soldering, whereas the Throwing Star LAN Tap Pro is available as a fully assembled, enclosed device. Both versions support communication diagnostics, protocol analysis, and authorized LAN infrastructure security testing. Similar network analysis tools can be found in the Cybersecurity category.
