Lime creates open-source RF hardware project

The transceivers come with well-defined digital connections on one side, to go to FPGA or DSP basebands, and RF connectors to power amplifier front-end on the other, said Bushehri.

Bushehri said he hoped that complementary component makers such as vendors of power amplifiers, antennas, FPGAs and DSPs would also get involved with the initiative.

When asked why it had not been chosen to address RF innovation by contributing to one of the established open-source digital hardware initiatives such as Arduino, Raspberry Pi, or Mbed, Bushehri said that one problem is that there are so many of these initiatives it would result in redundant work in each forum.

By forming a stand-alone open-source initiative focused on configrable RF it was hoped that work could be done once and links made to multiple digital hardware initiatives through well-defined interfaces. Bushehri said.

Lime is not the first to try and stimulate the creation of an open-source RF community. Open-Source RF (Irvine, Calif.) is a venture founded by Armen Kazanchian in mid-2012 under the Kickstarter program. It is looking to serve Arduino users with a plug-and-play wireless board for Arduino. The board, known as a shield, operates on a 2.4GHz carrier frequency and includes an antenna. Apex Logic is an organisation that creates open-source prototypes addressing a variety of applications and has developed low-cost RF transceiver designs and code for Arduino based on transceiver ICs that operate at 433MHz.
