Lime Microsystems has launched a crowdfunding campaign for the LimeNET Micro, an all-in-one device which combines the LMS7002M field-programmable radio frequency (FPRF) chip with a Raspberry Pi Compute Module 3, bringing the LimeNET family to its lowest price point yet. Designed with narrowband applications in mind, the LimeNET Micro operates…

The team from Lime Microsystems will be at the Telecom Infra Project (TIP) Summit in London next week, with a range of LimeNET and CrowdCell demonstrations. Part of the cross-vendor Telecom Infra Project (TIP), founded to encourage openness and disaggregation in access, backhaul, and core & management of a modern…

While most users of the LimeSDR focus on its LMS7002M radio frequency integrated circuit (RFIC), naturally enough, there’s flexibility to be found also in its field-programmable gate array (FPGA) – as proven by Gaspar Karm’s project to add a DC-removal filter into the board’s gateware. As the name suggests, a…

Vodafone and Lime Microsystems have announced the first in a planned series of annual hackathon events designed to benefit the Telecom Infra Project, focused on developing on top of the LimeSDR powered CrowdCell platform. A part of the Telecom Infra Project, which aims to drive innovation in the telecommunications arena…

LimeSDR units will be a key feature of this year’s Electromagnetic Field (EMF Camp) event, taking place in the UK this weekend, powering a local GSM cellular network for attendees’ use. Part camping festival, part gigantic temporary hackspace, Electromagnetic Field is this year held in Eastnor, UK, and on…

Satellite communications specialist Planet Labs has announced its entry into the open-source radio community, with an open-hardware device dubbed the OpenLST built exclusively using widely-available commercial off-the-shelf (COTS) parts. “Radio system design is often viewed as a ‘black box’ that is out of reach to all but the most experienced…

This fortnight’s big news was, of course, the successful rescue of 12 children and one adult stranded in a Thai cave by flooding, and there’s a surprise twist in the tale: the rescue was carried out using USB radio transceivers designed by a radio ham. Hackaday explains that members…

Engineer Mark Zachmann has posted of his work using the LimeSDR Mini to test low-power long-range LoRa radios, as part of an Internet of Things (IoT) project. “I’m working on a LoRa system at 915MHz. LoRa is a frequency modulation method used on low power IOT devices. Being able to…

Community member Lucas Riobó has, alongside colleagues Francisco Veiras, María Garea, and Patricio Sorichetti, announced a novel use for a LimeSDR: software-defined optoelectronics. “In this work, we propose a general architecture for the implementation of Software-Defined Optoelectronic systems (SDOs),” Lucas explains in the forum post announcing the early-access publication…

Work to deliver outstanding LimeSDR, LimeSDR Mini, and associated devices continues, but there’s been a major change in the background: Crowd Supply is now in full control of inventory management and distribution, which is going to make future fulfilment considerably smoother at the cost of a moderate delay in the…

A new Python package, pyLMS7002Soapy, has been published as a more feature-packed replacement for the old pyLMS7002M library – bringing with it bundled examples which use the LimeSDR or LimeSDR Mini as a scalar or vector network analyser (SNA/VNA). Uploaded to the Myriad RF GitHub repository late last month the…

Fulfilment of the LimeSDR Mini pre-orders continues, with the optional aluminium cases for the bundles having gone through assembly and testing ready for Crowd Supply to send them on. Delivered late last week and pictured in a campaign update, the LimeSDR Mini aluminium cases are designed to provide protection…
