GPIO Board and Hacker Case

We are pleased to announce two new accessories for the LimeSDR: the GPIO Board and Hacker Case. Pre-orders placed now will be delivered in December 2017.

A LimeSDR and the new GPIO Board

GPIO Board

We designed the GPIO Board for use with the LimeSDR, to enable sensing inputs and controlling relays for TX/RX switching, filter selection, etc. Here are the details:

  • Provides bi-directional level shifted I/O for FPGA GPIO 0-7
    • 1.2 - 5.5 V I/O on J2
  • Each I/O has a high voltage and power Darlington drive stage
    • Rated for 30 V @ 300 mA (0-4) and @ 200 mA (5-7)
    • Suitable for inductive loads, e.g., coaxial relays
  • Input/Output direction is individually switchable
  • LimeSDR form factor (can be stacked)
  • Individual, high quality, pluggable load connections

Soon we will provide the schematics, board layout, etc. of this fully open source design, as well as Python example code.

Perfect for applications such as amateur radio and test and measurement, where it’s necessary to control things such as coaxial relays and sense signals from power amplifiers and the like.

Hacker Case fitted with a LimeSDR and GPIO Board

Hacker Case

We designed this new acrylic case to accommodate both the LimeSDR and matching GPIO Board. It includes SMA connectors for all RF ports and a 40 mm cooling fan. Please note that these images show a prototype. The final version will have two additional mountings for SMA connectors at the rear panel, for CLK I/O.

$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.


$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.
