LimeSDR is an open source, apps-enabled software-defined radio (SDR) platform that can be used to support just about any type of wireless communication standard; it can transmit and receive UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee, RFID, and Digital Broadcasting, to name but a few.

The LimeSDR platform is comprised of a family of boards that range from a cost optimised 1×1 SISO board and a highly affordable 2×2 MIMO solution — both with USB3.0 interface — up to

  • RF Transceiver: Lime Microsystems LMS7002M FPRF
  • FPGA: Altera Cyclone IV EP4CE40F23 – also compatible with EP4CE30F23
  • Memory: 256 MBytes DDR2 SDRAM
  • USB 3.0 controller: Cypress USB 3.0 CYUSB3014-BZXC
  • Oscillator: Rakon RPT7050A @30.72MHz
  • Continuous frequency range: 100 kHz – 3.8 GHz
  • Bandwidth: 61.44 MHz
  • RF connection: 12x U.FL connectors (6 RX, 4 TX, 2 CLK I/O)
  • Power Output (CW): up to 10 dBm
  • Multiplexing: 2×2 MIMO
  • Power: Micro USB connector or optional external power supply
  • Status indicators: programmable LEDs
  • Dimensions: 100 mm x 60 mm

The first of the LimeSDR Field Reports has been published, courtesy of community member Daniel Estévez: a look at his LimeSDR Mini-powered satellite ground station project. “My project uses a LimeSDR Mini as the basis for a ground-station for the amateur radio transponders on the geostationary satellite ‘Es’hail 2’ (known…

OTA: LimeSDR WSPR, Angle of Arrival Experiments, DSPs without Maths, and More

Community member Kiril Miloshev has been interviewed for the Lime Micro Community Hub, on his experiments with Weak Signal Propagation Reporting (WSPR) using the LimeSDR Mini. “Software defined radios got my attention as they are very universal, and you can do whatever you can imagine with them. Especially ones like…
