Encouraged by the strength of proposals in the LimeSDR early access competition and keen to see what projects the community might build that make use of the FPGA, we’ve decided to run a second competition where this time the focus is putting the LimeSDR’s Altera Cyclone IV to good…

The competition drew to a close last week and I have to say that judging has not been easy, on account of there being no shortage of great entries, with many more proposals for uses that we'd really love to support than boards we have available at this point in time.

The crowdfunding campaign may have drawn to a close — and what a fantastic result! — but work continues in the core engineering team in order to get full scale production and testing in place, and also in the community of beta testers which have early access to LimeSDR hardware.

Paired with a suitable host platform and thanks to the remote capability provided by the driver infrastructure, LimeSDR can be used as the basis of a remote radio head (RRH) that is mounted closer to the antenna, with configuration and streaming carried over an IP link to another host that is running the actual SDR application.

LoRa is a chirp-based modulation format that can operate beneath the noise floor. Its robust, low power, and low rate -- and a candidate technology for connecting the internet of things. In this blog I will cover the basics of LoRa modulation, show off the LoRa PHY blocks for Pothos, and demonstrate simple relay and client applications using a pair of LimeSDRs.

We're pleased to announce that the design and manufacturing files for the PCIe variant of the LimeSDR board have now been published to GitHub, together with the associated FPGA project.

One of the reasons why I find the LimeSDR interesting is that it can transmit high data rates over a wide frequency spectrum. It covers many ham radio bands where we can legally transmit wide signals using high power. This allows us to experiment cutting edge technologies such as digital video transmission over the air.

When the new Lime SDR arrives at your doorstep, you will find that its immediately usable within a variety of existing SDR applications and software stacks.

My LimeSDR board arrived on April 26, a day before the crowdfunding campaign was launched. I made an agreement to test the board and post my experiences here on the MyriadRF blog. This is the first out of hopefully many posts I will make about the LimeSDR.

Lime Suite is a collection of software supporting several hardware platforms including the LimeSDR, drivers for the LMS7002M transceiver RFIC, and other tools for  developing with LMS7-based hardware. This post will cover the components of Lime Suite, how it supports LimeSDR, how it fits with the SDR application ecosystem,…

Some may have seen via Twitter, various blog posts, at Mobile World Congress back in February, or the recent EE, Lime Micro and Canonical joint announcement, that there is a particularly exciting new SDR platform on the block — the incredibly compact USB 3.0 peripheral, LimeSDR. As an SDR platform…
