LimeSDR Mini Information
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 |
LimeSDR Mini FPGA Gateware
The LimeSDR Mini FPGA Gateware description can be found here LimeSDR Mini Gateware_Description V01r00
Standard Gateware is used for Portsdown 2019.
Custom LimeSDR Mini FPGA Gateware
Custom LimeSDR Mini FPGA Gateware for DVB transmissions is available at https://github.com/natsfr/LimeSDR_DVBSGateware. To drive this gateware, F5OEO's limesdr_dvb.cpp software should be used with the -F flag: https://github.com/F5OEO/limesdr_toolbox
This gateware will be incorporated into Portsdown Buster 2020.
Accelerated Spectrogram Gateware
Custom gateware for spectrum analysis is described here: https://limemicro.com/community/limesdr-mini-fpga-accelerated-real-time-spectrogram/ The gateware is on GitHub here: https://github.com/gasparka/LimeSDR-Mini_GW and the software to drive it here: https://github.com/gasparka/spectrogram
LimeSDR Command Line Utilities
A number of LimeSDR utilities are available from the Linux command line in the Portsdown software build:
| Function | Command | Returns |
|---|---|---|
| Check LimeSDR Connected | LimeUtil --find | List of Devices |
| Check LimeSDR Firmware | LimeUtil --make | Hardware, firmware and gateware Versions |
| Update Firmware | LimeUtil --update | Progress report |
| Software version | LimeUtil --info | Installed LimeUtil SW Version |
| Self-test | LimeQuickTest | Results of tests |
Other Application Software for the LimeSDR Mini
SDRAngel runs on Windows 10 and Linux and can be used to demodulate voice and DATV signals: https://github.com/f4exb/sdrangel
SDRConsole runs on Windows 10 and will receive and transmit using the LimeSDR: https://www.sdr-radio.com/
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: http://v.1337team.tk/dvb-s_gui_amsat.zip
