We've been amazed and incredibly encouraged by the achievements of those in the community who we were able to provide with early access to LimeSDR hardware; from receiving weather satellites, to running 2G and 4G cellular base stations, and even HD TV broadcasting — the uses to which it has been put in a very short period of time far exceeded our expectations.

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.

As part of a continuing effort to improve both the accessibility and usability of technical documentation relating to the Myriad-RF project, launched last year as the Myriad-RF WIki Documentation Initiative, we're pleased to announce that the Lime Micro LMS7002M Field-Programmable RF IC Datasheet is now available on the Wiki alongside new documentation relating to the Stream Protocol.

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.

The latest project to join the Myriad-RF family is concerned with the creation of RF front-end modules, which can be used together with an SDR platform in order to create a custom wireless solution.

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.

We’re pleased to announce that the User Guide for the LimeSDR open-source software defined radio (SDR) platform is now available on the Myriad-RF Wiki. This forms part of the ongoing Myriad-RF Wiki Documentation Initiative, launched in 2015 to increase the accessibility of technical documentation relating to Myriad-RF projects.

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,…
