The USRP B205mini-i is a flexible and compact platform that is ideal for both hobbyist and OEM applications. It is designed by Ettus Research™ and provides a wide frequency range (70 MHz to 6 GHz) and a user-programmable, industrial-grade Xilinx Spartan-6 XC6SLX150 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.

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. Do you prefer graphical programming? Try out GNU Radio, a free and open-source software development framework offering a graphical design approach.
