The LimeSDR operates in conjunction with a USB-connected SBC or other system running Canonical’s lightweight, transaction-capable Snappy Ubuntu Core Linux distribution, which manages the board’s Altera Cyclone IV FPGA. LimeSDR front (upper) and back (lower) views A $799 version of the board with a PCIe interface ships Nov. Models with cases, cables, and antennas ship Oct. The CrowdSupply campaign ends June 21, with the $299 board shipping Nov. is part of Lime Micro’s Myriad-RF project for open source wireless communications. The LimeSDR can send and receive using UMTS, LTE, GSM, WiFi, LoRa, Bluetooth, Zigbee, RFID, Digital Broadcasting, and many other standards, says the company’s community project. Other applications include academic, industrial, hobbyist, and scientific, such as radio astronomy. The device can be used as a low-cost multi-lingual cellular base station or as the guts of an IoT wireless gateway that can handle any wireless standard you can throw at it.
The LimeSDR’s FPGA manages DSP and interfacing tasks, while a USB 3.0-connected host SBC or other system running Snappy Ubuntu Core provides user interface and various high-level supervisory functions.
Like other Linux-based SDR systems we’ve seen, the LimeSDR uses an FPGA to help orchestrate wireless communications that can be tuned, manipulated, and reconfigured to different wireless standards via software.
UK-based Lime Microsystems, which develops field programmable RF (FPRF) transceivers for wireless broadband systems, has launched an open source software defined radio (SDR) board on CrowdSupply. The open source LimeSDR board supports user-defined radios ranging from ZigBee to LTE, under control of a USB-interfaced system running Snappy Ubuntu Core.
