Introducing the Driver Architecture

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.

Fortunately, with quite a bit of experience under our belt we knew from the outset just how crucial software support is. And with this in mind we enlisted the help of Josh Blum in putting together a driver infrastructure for not just LimeSDR, but any board that is based around the LMS7002M FPRF transceiver. Which could be a derivative of LimeSDR — given that it’s fully open source hardware and anyone is free to fork the design — or it could be a completely new board.

For those not in the know, Josh is the original author of the WYSIWYG flowgraph editor for SDR applications, GNU Radio Companion. In addition to being the creator of dataflow programming software suite, Pothos — and SoapySDR, the vendor and platform neutral SDR support library.

SoapySDR was the obvious choice for providing the LimeSDR host API, not just because it strives to be vendor and platform neutral, but because thanks to its extensible nature it provides lots of other great features, such as compatibility with tons of existing apps via support for the UHD API.

In a new post up on the Myriad-RF blog, Josh takes us through the Lime Suite architecture, introducing the various components, connection interface and registry, support for custom hardware, GUI and SDR APIs. This will hopefully answer a lot of those questions and should any remain, please post them to the new Lime Suite category on the Myriad-RF forums.

Enjoy!

$289

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. 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.


$799

Ultimate LimeSDR With PCle Interface

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. 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 PCIe interface, cables and Antennas for a quick set up. Stretch goal: if 30 units are sold, all pledges for this level will include dual-channel PA and LNA modules, together with a set of eight SAW filters covering TX and RX on bands I, II, V and VII. See updates for more details.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency range from 800-960 / 1710-2170/ 2400-2700MHz.


$15,000

Enterprise 10 Pack - LimeSDR + Aluminum + Accessories

This package comes with 10 customized high quality enclosures with logo of the sponsor enterprise. The bundle comes with a complete suite of software and set of accessories for an out of the box experience. The package includes a one day training course at the headquarters of Lime Micro in Guildford, England or other designated locations for an extra fee to be agreed with the sponsor organization (not including airfare). On completion of the course, the participants are presented with a certificate following a practical exam in setting up the LimeSDR for one of the use cases presented in the updates during the campaign. The maximum number of attendees will be 10.


$99,000
