LimeSDR Mini

LimeSDR Mini is ideal for developing logic-intensive wireless systems, and can be used as-is for small and medium volume production quantities or incorporated into cost-optimized products for mass production.

LimeSDR vs LimeSDR Mini

The LimeSDR and LimeSDR Mini are members of the same family of software-defined radios. One does not replace the other. Rather, they are complementary.

Simply put, the LimeSDR Mini is a smaller, less expensive version of the original LimeSDR. However, it still packs a punch – at its core, the LimeSDR Mini uses the same LMS7002M radio transceiver as its big sibling. The Mini has two channels instead of four and, by popular demand, SMA connectors instead of micro U.FL connectors, and features Intel’s MAX 10 FPGA.

We’ve shipped many thousands of LimeSDR Mini boards, along with thousands of the larger LimeSDR boards. Both of which are built on the same supply chain, development tools and community, in a way that makes software-defined radio more accessible than ever.
