LimeSDR Mini 2.0

LimeSDR Mini 2.0 is an upgraded, drop-in replacement for LimeSDR Mini, a hardware platform for high-performance and logic-intensive digital and RF designs that use an FPGA coupled with Lime Microsystems’ LMS7002M RF transceiver. It has the same form factor as the original LimeSDR Mini and the same RF transceiver, but a new FPGA — the Lattice ECP5 — which has more resources and benefits from an extensive set of open source tools and a vibrant community of developers.

Since we first introduced LimeSDR over eight years ago, and LimeSDR Mini about a year later, we’ve shipped tens of thousands of units to engineers around the world for use in everything from satellite ground stations to digital television.

Whether you’re a hobbyist using the LimeSDR platform to learn about software-defined radio, or a company integrating hundreds of units into your commercial product, we’ve been thrilled at the breadth and depth of LimeSDR Mini applications that you've come up with.

An open, full-duplex, USB stick software-defined radio

It can be used in conjunction with host computers of varying speed, power dissipation and cost, to fit any air interface, whether narrowband or broadband. The board is designed for the following key features:

Frequency and Bandwidth: The heart of the board is the Lime transceiver RFIC (LMS7002), covering frequencies up to 3.8 GHz with a bandwidth of up to 40 MHz.
Baseband Interface: A significant level of digital circuitry resides within the LMS7002 and accompanying FPGA for the implementation of key physical layer radio functions, including filtering, decimation and interpolation. Interfacing is via USB 3.0.

Applications

The SDR community has has used Lime products for a wide range of applications, such as:

Since LimeSDR Mini 2.0 has an FPGA with even more logic gates than its predecessors, we expect the number and types of applications to increase accordingly.
