NI Ettus USRP B205mini-i: 1x1, 70MHz-6GHz SDR/Cognitive Radio

Please Note: The B205mini-i is now in the final stage of its lifecycle and is no longer recommended for new designs. For ongoing and future projects, we recommend transitioning to the B206mini-i, which offers enhanced performance and continued long-term support.

The USRP B205mini-i is a flexible and compact platform that is ideal for both hobbyist and OEM applications. It is designed by NI Ettus USRP and provides a wide frequency range (70 MHz to 6 GHz) and a user-programmable, industrial-grade AMD Spartan-6 XC6SLX150 FPGA. The similar Ettus USRP B200mini is limited to a narrower operating temperature range and utilizes a smaller FPGA.
The RF front end uses the Analog Devices AD9364 RFIC transceiver with 56 MHz of instantaneous bandwidth. The board is bus-powered by a high-speed USB 3.0 connection for streaming data to the host computer. The USRP B205mini-i also includes connectors for GPIO, JTAG, and synchronization with a 10 MHz clock reference or PPS time reference input signal.
Experimentation with Low-cost SDR
Experiment with the USRP B205mini-i across a wide range of applications including: FM and TV broadcast, cellular, GPS, WiFi, ISM, and more. Users can immediately begin prototyping in GNU Radio and participate in the open-source SDR community. Full support by the USRP Hardware Driver™ (UHD) software allows seamless code reuse from existing designs, compatibility with open-source applications like HDSDR and OpenBTS, and an upgrade path to industry-ready USRP systems to meet application requirements.

The hardware is conveniently accessible through the USRP Hardware Driver (UHD). UHD provides both a C/C++ and Python API that supports all USRP products and enables users to efficiently develop applications then seamlessly transition designs between platforms as requirements expand. UHD also offers cross-platform support for multiple industry standard development environments and frameworks, including RFNoC, LabVIEW, and MATLAB/Simulink. To ensure you have no restrictions on how you use UHD, it is available on Linux, Windows, and Mac OS. Do you prefer graphical programming? Try out GNU Radio, a free and open-source software development framework offering a graphical design approach.
