The SignalSDR Pro is designed for seamless integration with a wide range of software platforms, making it a versatile solution for numerous applications. It is fully compatible with industry-standard tools such as GNU Radio for signal processing, MATLAB for advanced computational tasks, and LabView for hardware control.

The device supports DragonOS, an open-source operating system optimized for SDRs, as well as LTE Sniffer and Open5GS for cellular network analysis. It also works with srsRAN for 4G/5G radio access network simulations, GPS-Sim-SDR for GPS signal emulation, OpenBTS for GSM base station creation, and GQRX for general signal analysis. These features ensure reliable and efficient performance across a broad spectrum of SDR applications. The GitHub repository has more information about the hardware along with tutorials and use cases for getting started.

The SignalSDR Pro campaign on CrowdSupply successfully surpassed its funding goal. Priced at $899, the package includes a heatsink case, a microSD card, 5G antennas, a GPS antenna, cables, and two preloaded SIM cards. Shipping is free within the U.S., with a $12 fee for international orders. Deliveries are expected to start by mid-March 2025.
