  • Open-source SDR receiver and transmitter

  • Frequency coverage 0.1MHz to 3.8GHz full-duplex

  • Bandwidth of 64Mhz, 2x2 Mimo

  • Transmit and Receive UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee or RFID


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

While most SDRs have remained in the domain of RF and protocol experts, LimeSDR is usable by anyone familiar with the idea of an app store - it’s the first SDR to integrate with Snappy Ubuntu Core. This means you can easily download new LimeSDR apps from developers around the world. If you’re a developer yourself, you can share and/or sell your LimeSDR apps through Snappy Ubuntu Core as well.The LimeSDR platform gives students, inventors, and developers an intelligent and flexible device for manipulating wireless signals, so they can learn, experiment, and develop with freedom from limited functionality and expensive proprietary devices. 

The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.

Over the last three years, the team has worked on numerous open source projects, all made available through Myriad-RF. This is no different, open source is central to LimeSDR: 

Board schematics: Altium project files available under CC BY 3.0 license. 

Board layout: Altium project files available under CC BY 3.0 license. 

Manufacturing: Gerbers, drill, and pick & place files are also available under CC BY 3.0 license. 

FPGA: Altera Quartus project available under CC BY 3.0 licence. 

Host connectivity: Cypress FX3 USB 3.0 controller firmware sources available under Apache 2.0 license.

Host software: driver and GUI sources available under Apache 2.0 license. 

Programming toolchain packages: GNU Radio, Pothos, SoapySDR, UHD. 

Documentation: transceiver datasheets are NDA-free. 

Downloadable apps: Snappy Ubuntu Core, licensing up to app developers. 

Like the move to open source software with general purpose computers, the programmable, fully open source LimeSDR represents a fundamental shift away from the traditionally single-function and heavily proprietary wireless domain.
