YARD Stick One

The YARD Stick One is a software-defined radio (SDR) transceiver that operates across a wide frequency range from 1 MHz to 1 GHz, enabling RF engineers and security researchers to transmit and receive radio signals for analysis and testing. Professional penetration testers, RF engineers, firmware developers, and electronics hobbyists use this device for spectrum analysis, signal interception, protocol reverse-engineering, and wireless security assessments. This tool solves the critical problem of affordable, portable RF signal capture and analysis without requiring expensive laboratory-grade spectrum analyzers.

Product Overview

The YARD Stick One is a half-duplex transceiver built on the CC1111 microcontroller platform, allowing simultaneous transmission and reception of radio signals across multiple frequency bands including ISM bands, cellular frequencies, and amateur radio frequencies. It connects via USB to a host computer and operates with open-source firmware, providing complete control over modulation schemes, data rates, and frequency selection. The device features a simple monopole antenna connector and operates at 3.3V logic levels, making it compatible with standard microcontroller development environments and RF analysis software suites.

What distinguishes the YARD Stick One is its exceptional value proposition combining hardware affordability with powerful software capabilities. Unlike traditional spectrum analyzers costing thousands of dollars, this compact device delivers professional-grade RF analysis and transmission capabilities in a pocket-sized form factor. The open-source ecosystem surrounding this device enables custom firmware development, allowing engineers to implement proprietary protocols, perform advanced signal processing, and integrate RF testing into automated security assessment workflows.

How to Use

Begin by installing the appropriate software drivers and SDR tools on your computer. Connect the YARD Stick One to a USB port on your host machine. The device will enumerate as a USB serial device. Install open-source software such as GNU Radio, GQRX, or Wireshark with RF plugins to begin capturing and analyzing signals. Configure the frequency, modulation type, and data rate parameters based on your target signal characteristics. For transmission applications, load custom firmware onto the CC1111 microcontroller using the bootloader mode, which is accessed by holding the bootloader button during USB connection.

When performing RF analysis, attach an appropriate antenna to the SMA connector based on your target frequency range. For lower frequencies (1-100 MHz), use a longer monopole or dipole antenna. For higher frequencies (400 MHz-1 GHz), shorter antennas optimized for those bands provide better reception. Start with receive-only mode to characterize the RF environment before attempting transmission. Always verify local regulations regarding RF transmission on your target frequencies. Document signal characteristics including frequency, bandwidth, modulation scheme, and packet structure for comprehensive protocol analysis and reverse engineering efforts.

Frequently Asked Questions

What is the difference between YARD Stick One and other SDR devices like HackRF or USRP?

YARD Stick One is optimized for low-cost, portable RF analysis with emphasis on ISM band frequencies and wireless protocol testing. HackRF offers higher frequency coverage (1 MHz to 6 GHz) and higher bandwidth but at significantly higher cost. USRP devices are laboratory-grade platforms with superior performance metrics but require substantial investment. YARD Stick One excels in field penetration testing, protocol reverse engineering, and educational applications where portability and affordability are priorities.

Can YARD Stick One transmit and receive simultaneously?

YARD Stick One operates in half-duplex mode, meaning it can transmit or receive but not simultaneously on the same frequency. However, the device can rapidly switch between transmission and reception modes, enabling near-simultaneous operation for many practical applications. For true full-duplex operation, you would need more advanced SDR platforms like HackRF or USRP with multiple RF frontends.

What programming languages and software are compatible with YARD Stick One?

YARD Stick One is compatible with GNU Radio (Python-based), GNURadio Companion (visual programming), GQRX (spectrum analysis), Wireshark (packet analysis), and custom C firmware development through the CC1111 bootloader. The device supports Python libraries like PyUSB for direct hardware control. Open-source projects like Goodfet provide firmware alternatives for specialized RF applications. Most SDR software frameworks support YARD Stick One through standard USB serial interfaces.

What antenna should I use with YARD Stick One?

The choice of antenna depends on your target frequency range. For 433 MHz ISM band, a quarter-wave monopole antenna (approximately 17 cm) provides optimal performance. For 868/915 MHz bands, use shorter antennas around 8-10 cm. For lower frequencies below 100 MHz, longer antennas (30+ cm) are necessary. SMA female connectors on the device accept standard RF antennas. For broadband analysis across the entire 1 MHz to 1 GHz range, use log-periodic or discone antennas designed for wideband reception.
