Lime Microsystems LimeSDR Mini 2.0

Lime Microsystems LimeSDR Mini 2.0 is an open-source USB stick software-defined radio based on the LMS7002M RF Transceiver and the Lattice Semiconductor ECP5 FPGA. The LimeSDR Mini 2.0 supports a frequency range from 10MHz to 3.5Ghz, full-duplex reception and transmission, 40MHz of radio-frequency bandwidth, and a USB 3.0 interface to a host device. The ECP5 FPGA offers 44k onboard programmable logic gates, ideal for projects where the user wants to perform operations on-device and ease the load on the host processor.

The Lime Microsystems LimeSDR Mini 2.0 features a compact 69.0mm x 31.4mm form factor. Two SMA connectors allow connection to standard multi-band antennas.
