OTA: Meet the LimeSDR Micro, Simulate Antennas In-Browser, Tianwen-1 is Back, and More

Lime Microsystems has opened a crowdfunding campaign for the latest entry in the LimeSDR family of software-defined radios: the LimeSDR Micro, a two-in-one M.2 module capable of acting as a traditional software-defined radio and/or as an accelerator for signal processing. The LimeSDR Micro is based on the Lime Micro LMS7002M,…

OTA: Wavelet Lab Opens xSDR Crowdfunding, a Microcontroller TV Transmitter, Decoding ESCAPADE, and More

Wavelet Lab has opened crowdfunding for its xSDR, the more compact of two planned M.2 software defined radio modules built around Lime Microsystems’ LMS7002M field-programmable radio-frequency chip – the same as powers the LimeSDR range. “Like uSDR, xSDR is built around simplicity, accessibility, and collaboration, now with expanded performance and…

OTA: Wavelet Lab Unveils the xSDR and sSDR, Visualising Wi-Fi, Tools for CubeSats, and More

Wavelet Lab, creator of the uSDR software-defined radio module, is preparing to launch crowdfunding campaigns for two new modules built around Lime Microsystems’ LMS7002M: the compact xSDR and wider-range sSDR. “xSDR is a compact, single-sided M.2 software-defined radio designed for seamless integration into modern computing platforms,” says Wavelet Lab’s Andrew…

OTA: LimeSDR Micro, Lunar GNSS Decoding, MAVEN Goes Quiet, and More

Lime Microsystems has been working on a new, low-cost entry in the LimeSDR family of software-defined radio devices: the LimeSDR Micro, designed to fit into M.2 and mini-PCI Express (mPCIe) slots. “LimeSDR Micro represents a breakthrough in software-defined radio technology, delivering professional-grade SDR with integrated baseband processing,” the company says…

OTA: Decoding ESCAPADE, the PhaseLatch Mini, an Antenna Spotter’s Guide, and More

Daniel Estévez has written of his work to decode ESCAPADE, a mission launched earlier this month aboard Blue Origin New Glenn mission NG-2 and with the goal of studying Mars. “ESCAPADE is a twin spacecraft mission that will study the Mars magnetosphere. The science mission is led by UC Berkeley…

OTA: An LMS8001 Demo, Signal Generation, Satellite Backhaul Security Woes, and More

Lime Micro’s Andrew Back has demonstrated how the LMS8001 Companion Board, a programmable frequency-shifting add-on for software-defined radio boards, can expand the capabilities of the LimeSDR Mini and other SDR families to 10GHz and beyond, without the need for any special software or hardware modification. “In this simple demo, we…

OTA: LMS8001 Companion Board Documentation, SDRing Like it’s 1977 and 1994, Selfies from Space, and More

Documentation for the Lime Microsystems LMS8001 Companion Board has now been made publicly available, including full details on what’s changed since its limited production run in 2017. “We are pleased to announce that documentation for LMS8001 Companion has now been published,” Lime Micro’s Andrew Back wrote in the latest campaign…

OTA: LMS8001 Companion Board and its 3cm/10GHz Band Performance, a Literal “Watch Tower”, and More

The LMS8001 Companion Board’s crowdfunding campaign is now live, and the response has been fantastic – including with questions from backers eager to use the device on the 3cm/10GHz amateur radio band for Earth-Moon-Earth communication, satellite tracking, radio astronomy, and more. “Years after the initial release of engineering samples of…

OTA: A New LMS8001 Companion Board, A LimeSDR XTRX M.2 Adapter, Biometrics via Wi-Fi, and More

Lime Microsystems has opened pre-launch registrations for a crowdfunding campaign to deliver a new LMS8001 Companion Board – a four-channel frequency shifter which can boost the frequency range of a software-defined radio up to 10GHz. “Lime’s LMS8001 Companion Board can extend the frequency range of any of the boards in…

OTA: Seeing Through Walls with a LimeSDR Mini 2.0, Better LibreCellular Hardware, Satellite AI, and More

Researchers Ben Pearman and Anand Kumar have put a LimeSDR Mini 2.0 to use in a very unexpected way: seeing through walls, with the help of an artificial intelligence (AI) model. “We humans inhabit a world of sight, sound, smell, taste, and touch. We cannot directly perceive the electromagnetic fields…

OTA: A Unified LimeSDR Gateware, Bouncing Signals off Venus, SignalAtlas, and More

The LimeSDR family is set to get a new, more flexible gateware for its on-board field-programmable gate array (FPGA) chips – in a complete rewrite which will unify all the various models together. The LimeSDR GW Project, launched this month for the LimeSDR Mini v1 and v2 and the LimeSDR…

OTA: LimeSDR USB Type-A Returns, DMR Transmission, Open Source VoWiFi Client, and More

Lime Microsystems has announced the relaunch of the LimeSDR USB Type-A, the full-size two-full-duplex-channel alternative to the popular LimeSDR Mini and LimeSDR Mini 2.0 – now in stock on Crowd Supply. “The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and…
