An open, full-duplex, USB stick radio for femtocells and more. The LimeSDR and LimeSDR Mini are members of the same family of software-defined radios. One does not replace the other. Rather, they are complementary. Simply put, the LimeSDR Mini is a smaller, less expensive version of...

An ultra low power LoRa sensor node powered by just one CR2032 batter. By Harm Wouter Snippe: Do you want to measure temperature, connect a soil humidity sensor in your vegetable garden or monitor the air quality at your street corner? With the Fennec Development Board you are able to...

Teardown, Repair & Upgrade of an Agilent E4405B 13.5GHz ESA-E Spectrum Analyzer -...

The researchers at Stanford University have discovered two ultrathin semiconductors – hafnium diselenide and zirconium diselenide. They share or even exceed some of the very important characteristics of silicon. Silicon has a great property of forming "rust" or silicon dioxide (SiO2)...

A joint research by the US Air Force Research Laboratory Sensors Directorate and Michigan State University have developed micro-electromechanical systems (MEMS) actuator based on smart materials, specifically vanadium dioxide (VO2). In the room temperature, Vanadium dioxide exhibits...

The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usually. It is based on Linear’s LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and signal traces and components at the...
