The LimeSDR Mini development board is a hardware platform for developing and prototyping high-performance and logic-intensive digital and RF designs that use Altera’s MAX 10 FPGA and Lime Microsystems’ LMS7002M RF transceiver.

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. Check out the comparison table below for more details.

Free & Open Source
As with the original LimeSDR, the LimeSDR Mini is a free and open source project made in collaboration with the Myriad-RF project. We will be releasing code, firmware, schematics, layout, and associated project files shortly.
The LimeSDR Mini uses the same host-side software, called LimeSuite, as the full-size LimeSDR. LimeSuite is entirely open source and supports a variety of software-defined radios. You can learn more about LimeSuite at its GitHub repository and Myriad-RF project page.
Snappy Ubuntu Core
A big part of the LimeSDR ecosystem is the Snappy Ubuntu Core app store being developed jointly with Canonical and the LimeSDR community. Because the LimeSDR and LimeSDR Mini use the same drivers and APIs, the snaps developed for one should work equally well for the other so long as they are within the operating specification.
