Full details of the LimeSDR Mini can be found on MyriadRF's web pages. Some key points are summarised here, together with links to useful MyriadRF web pages.

Hardware Specification

The BATC Shop-provided LimeSDR Minis are of hardware version v1.2. This is printed on the PCB near the mounting hole next to the USB connector. The full hardware specification can be found here: LimeSDR Mini v1.2 hardware description.

Earlier LimeSDR Minis may be of hardware version v1.1 described here: LimeSDR Mini v1.1 hardware description.

Indication LEDs

The LimeSDR Mini has a red/green LED near the SMA connectors; the meanings of the indications are:

Indication Meaning Example
Either LED steady, no blinking TCXO Clock not present Powered, but no USB data connection
Both LEDs steady, Amber TCXO Clock not present Powered, USB data connection lost
Either LED blinking TCXO Clock detected Connected to USB, drivers loaded
Red/green blinking At least one PLL not locked Connected to USB, drivers loaded
Green only blinking Both PLLs locked Transmitting

Other Application Software for the LimeSDR Mini

SDRAngel runs on Windows 10 and Linux and can be used to demodulate voice and DATV signals:

SDRConsole runs on Windows 10 and will receive and transmit using the LimeSDR:

The experimental "DVB-S GUI" program runs on Windows 10 (with high-end hardware) and will receive DVB-S and DVB-S2 using a Lime SDR. Notably, it applies LDPC error correction to DVB-S2 signals:
