Results for 'radio OR wireless'

In this latest demo we show the LimeSDR Mini being used with the incredibly popular Raspberry Pi 3. While this won’t run an LTE base station, it is perfectly capable of supporting a great many narrowband applications.

This latest demo comes courtesy of Adrian Musceac, community member and developer of the rather cool QRadioLink software.

New: xMASS SDR, VXSDR-20-160; Coming Soon: Ubo Pod, Jumperless V5, GenBook RK3588, ESPNetLink; Update Roundup: HealthyPi Move, Inkplate 6 MOTION, Conexio Stratus Pro, True Wireless Valve; In Stock: The New Essential Guide to Electronics in Shenzhen, Diabolic Drive

We designed True Wireless Valve (TWV) to achieve exceptional energy efficiency, enabling it to operate for up to two years on a single set of batteries. A key factor in this efficiency is the device's ability to enter sleep mode. TWV cannot remain asleep for too long, however, as it must be ready to respond instantly to commands from the user or automation signals from the hub. This update walks through the system of variable-polling intervals and explains how they contribute to TWV's long battery life.

Time for a quick rundown on last week’s developments…

We've received so many questions about the HF band and RF performance lower than 30 MHz, that we decided to do a special update.

An open-source, ESP32-powered doorbell-camera system that integrates with your home-automation setup

Environmental Monitoring for the Internet of Things

A USB-powered, low-priced, open source RF signal generator

Previously, I have published all the source code and fabrication files on GitHub. Today, I am going a step further and publishing the whole design project, so you can modify the design as you wish.

It's been a month since our campaign concluded, and we've been hard at work turning our shared vision into a tangible reality. We want to keep you in the loop about what's been happening and what's next for Boondock Echo! This update covers our manufacturing progress, our community-engagement efforts, and next steps.

We are thrilled to announce the launch of our crowdfunding campaign for LimeRFE, a highly configurable RF front-end that adds multi-band power amplification (PA) and a low noise amplifier (LNA), plus filtering and support circuitry for use with LimeSDR, LimeSDR Mini, and LimeNET Micro.

Our second annual party for hacking, discovering, and sharing hardware

Welcome new projects, Spacewalker LNA 434 MHz and LimeNet Micro 2.0, catch up on livestreams, LimeRFE now in stock.

Microchip’s AT86RF215 is a multi-band radio transceiver with dual Radio RF Front-ends—one sub-GHz and one at 2.4 GHz—that cover nearly all of the unlicensed IoT bands, making it ideal for all-in-one IoT solutions. This update delves into those capabilities and discusses a few of the ways in which iotSDR takes advantage of them.

Our campaign has officially ended. We just wanted to say a big thank you to our backers and all who have supported us throughout. In our view, wireless innovation has been limited by access to affordable, easy-to-use, maintainable and upgradeable hardware.

We're thrilled to welcome Qorvo as a sponsor of Teardown. Select Crowd Supply projects are eligible to join the first-ever Qorvo RF Accelerator.
