Work on a LimeSDR Project with Google Summer of Code

For those unfamiliar with Google Summer of Code, it is described as “a global program focused on introducing students to open source software development. Students work on a 3 month programming project with an open source organization during their break from university.” With some pretty impressive figures and since it’s inception 12 years ago, it can lay claim to:

  • 12,000+ student participants
  • 11,000 mentors
  • Participation from across 127 countries
  • Producing 30,000,000+ lines of code for 568 open source organizations

It’s a fantastic initiative that has made a huge contribution to the open source community over the years.

We are delighted to have been selected as a mentoring organisation for the Free and Open Source Silicon Foundation’s participation in Google Summer of Code 2017. This is presently focused around two project ideas that make use of the LimeSDR platform:

  • Integrate RISC-V Core
  • Switch to a FuseSoC-based Development Flow

The first of these would see the NIOS-II processor that is currently being used for USB/SPI interfacing being replaced with an open source core implementing the RISC-V instruction set. The second project involves structuring the repository and adding the required infrastructure files for FuseSoC, so that this can be used to manage the dependencies and composition of hardware blocks for the softcore processor, along with glue logic, DSP, sample time-stamping, etc.

For further details, see the GSoC 2017 ideas page on the FOSSi Foundation website and perhaps take a look at the LimeSDR-USB_GW repository.

Have an idea for another great open source digital design project using LimeSDR that you’d like to work on? We’d love to hear from you and should be able to find a suitable mentor. There is plenty of scope for all manner of other exciting projects which make use of the LimeSDR’s FPGA!

Note that students will be provided with hardware in addition to receiving mentoring.

Shipping Update

Shipping continues! In about a week, we will announce the final manufacturing run needed to fill all remaining campaign orders and pre-orders. In the meantime, here’s the shipping status for each of the main LimeSDR boards. You can check the status of your order in your Crowd Supply account.

Limited Edition Early Bird - LimeSDR (a.k.a. the First Flock)

We are pleased to report that, with the exception of 13 people who explicitly requested the HF mod, everyone who backed the “Limited Edition Early Bird - LimeSDR” (a.k.a. the first flock) should either already have their LimeSDRs or at least a shipping confirmation email with a tracking number.

Early Bird (Second Flock) - LimeSDR

The status of your order depends on the connector type you chose.

Second Flock USB micro Type-B

All but about 50 of the second flock micro Type-B boards have shipped. If you ordered a micro Type-B board in the second flock and haven’t yet received your board or a shipping confirmation email, then you have either explicitly requested the HF mod or you will receive your board as part of the next manufacturing run of micro Type-B boards, the exact delivery schedule of which will be announced soon.

Second Flock USB Type-A

Shipping of the Type-A boards resumes today! The remaining Type-A boards in the second flock will ship this month, except for HF mod boards, as above. You will receive a shipping confirmation email with a tracking number once your order ships.

LimeSDR (Subsequent Flocks and Pre-orders)

Some of these have already shipped and most of the remaining Type-A boards will ship this month, but some orders will have to wait until the next manufacturing run, to be announced soon.

LimeSDR with Aluminum Kit

We’re on track to ship most of these in April. There may be a need for another manufacturing run, which will be announced soon.

Ultimate LimeSDR With PCle Interface

Over 90% of these orders shipped last week. If you were one of the few backers of this pledge level who hasn’t yet received a shipping confirmation email, you can expect to be included in the next manufacturing run, to be announced soon.

Thank you for your continued support and patience!

Product Choices

$299

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 PCIe 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.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency ranges 800-960 MHz, 1710-2170 MHz, and 2400-2700 MHz. Includes U.FL to SMA cables.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
