All the accessories, including the antennas, cables and acrylic cases have already been sent to Crowd Supply, ready to be shipped out along with boards to our backers. Read the full update.
With the first batch of boards on their way out to backers now seemed like a great time to thank our partners and the software-defined radio pioneers, who together with everyone who backed the campaign have helped to make LimeSDR possible. As such here’s a short video from Ebrahim Bushehri, CEO of Lime Micro and founder of Myriad-RF. Read the full update.

Since the successful close of our funding campaign, We've been incredibly busy preparing to deliver LimeSDRs to all our backers. Just as we worked hard during the campaign - internally, with key partners, and with our fantastic beta testers in the community — creating a series of exciting demos, we continue to work to ensure backers will have a first-class experience upon receiving their hardware. In this update, we'll review the state of the production schedule, hardware design, testing setup, documentation, app store, and more. Read the full update.
We’re delighted to announce that Charles Brain is the winner of our digital design competition, with a proposal to build an FPGA-based RF channel simulator. Read the full update.
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 use. Read the full update.
We are excited to announce that, as part of a manufacturing agreement with ASE Group -- the company that packages the LMS7002M transceiver IC -- all boards pledged during the campaign and any purchased before September 30th will have an ‘I Backed LimeSDR on Crowd Supply’ logo on top of the chip. Read the full update.
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. Read the full update.
Due to so many excellent competition submissions, there will now be two winners. Read the full update.

It's the Friday before the final few days of the campaign, we hit 80% funding and $400,000 earlier today, and we're still some way to go but it certainly feels like we can make it. As such, now seems like a great time to look back at achievements so far, with a look also towards the future. Read the full update.
In a new post up on the Myriad-RF blog, Andrew takes us through the hardware build for a remote radio head, which is to say a system that integrates RF and digital converters etc. that is used together with a second networked, remote system which then runs the actual SDR application. Read the full update.
First, thanks to everyone who has supported us so far. We're in the final week of the campaign and over three quarters the way to our funding goal! We're well within reach of the goal, but we'll need your help. The funding goal wasn't arbitrary - if we don't reach it, then the project will be put on hold, none of your credit cards will be charged, and no one will get a LimeSDR. Community-driven free and open source hardware projects rely on individuals' support to get off the ground. LimeSDR is no different. If you haven't yet pledged for a LimeSDR, please do! if you have, please help spread the word far and wide to everyone you know, be it by social media, email, in-person, or carrier pigeon. Read the full update.
Picking up where we left off yesterday with test and measurement examples, we have one this time from Lime's millimeter wave IC design team, demonstrating LimeSDR being used as a vector network analyzer (VNA). Read the full update.
All of the example applications that we've shared so far have been demonstrations of one form or another of wireless communications. And, while this is obviously the main use that we had in mind for LimeSDR, it is by no means the only one and it can equally be put to use in many other demanding RF applications that require signal generation and reception or measurement. Read the full update.
By popular demand, acrylic enclosures for LimeSDR are now available for separate purchase at a reduced price of $99. Read the full update.

Over the past few weeks we've shown how LimeSDR can be used with numerous different applications and wireless systems, and what better way to round off the week than with news that Josh has succeeded in putting together a series of Pothos-based examples for LoRa™ modulation. Read the full update.
While it's great that you can use LimeSDR with new wireless systems such as Bluetooth Low Energy, along with wideband ones such as HDTV broadcast, there are tons of applications that use really simple narrowband wireless systems for remote control and sensing. Read the full update.
In a new post up on the Myriad-RF blog, Andrew announces the availability of the design and manufacturing files, plus FPGA project files, for the PCIe variant of LimeSDR. Read the full update.

So if you have great hardware and software support, what comes next? Documentation! Read the full update.
Having a great hardware platform is one thing, but as any experienced engineer will tell you, this is only half of the story and you also need solid software support to realise the true potential of that hardware. So it's hardly surprising that we've had quite a few backers asking for more details of the driver software for LimeSDR and whether it will support this application or that application. Read the full update.
First, a big thank you to all our backers. With your support, we hit 20% of our campaign target in just over 24 hours and all 500 of the first flock of early bird boards were pledged within 32 hours.
