We are excited to announce that three new designs have been published to GitHub for boards that extend the Reference Development Kit and STREAM projects. These together provide an incredibly compact and low cost solution for prototyping wireless applications that are based on an Altera FPGA and Lime Microsystems FPRF.

The boards are also the first to implement the new uRFDIO interface, which has allowed Azio to create a micro version of the STREAM board, “uSTREAM”, along with micro versions of the transceiver module available in both LMS6002D and LMS7002M variants.

The FPGA board itself measures only 31mm x 108mm in size and along with an Altera Cyclone IV device incorporates a Cypress FX3 USB 3rd generation controller, 512M SDRAM, TCXO and Raspberry Pi 40-pin header.


GUI applications are provided for programming and calibration of the transceiver, along with TCXO configuration and FFT display of received signals. Python examples are also available for use with a Raspberry Pi SBC.

The wiki will be updated with further details over the coming weeks and general availability is expected early in the new year.
