Lime SDR Aluminium Kit
A Software Defined Radio for Everyone
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.

From Radio Astronomy to Personal Telcos
Here are just some of the applications that are possible with the LimeSDR:
- Radio astronomy
- 2G to 4G cellular basestation
- Media streaming
- IoT gateway
- HAM radio
- Wireless keyboard and mice emulation and detection
- Tire pressure monitoring systems
- Aviation transponders
- Utility meters
- Drone command and control
- Test and measurement
- Many more…
With state-of-the-art technical specs, fully open hardware and toolchain, and integration with Snappy Ubuntu Core’s app distribution platform, LimeSDR is limited only by our collective imagination.

Free and Open Source
LimeSDR is one of the open source projects, all made available through Myriad-RF. This is no different, open source is central to LimeSDR:
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.
Huge Application Ecosystem with Snappy Ubuntu Core
We’ve been working directly with the IoT team at Canonical, the makers of Ubuntu, to enable the use of Snappy Ubuntu Core on LimeSDR.
LimeSDR’s integration with Snappy Ubuntu Core means that you benefit from the collective work of developers around the world. With LimeSDR, we are laying the foundation for a world in which “there’s an app for that” applies not only to mobile phones, but also to the cell towers they connect to and, indeed, every wireless device or piece of infrastructure.
LimeSDR brings with it many opportunities for educational and maker communities, empowering them to learn, and create new applications and even new markets. LimeSDR puts serious power in the hands of anyone who wants to innovate in the world of wireless.
