Nordic Semi nRF21540 RF front end module Extends the Range of nRF52/nRF53 Bluetooth SoC’s

A little while ago, we wrote about RFCat N32 board integrating Meshtek-H52 module with nRF52832 2.4GHz multi-protocol SoC and a Skyworks power amplifier increasing power by up to 30 times to extend the wireless range to up to 200 meters. It turns out Nordic Semi outed its own range extender module late last year with nRF21540 RF front end module (FEM) that integrates a power amplifier (PA) and low noise amplifier (LNA) optimized to boost the link budget of the nRF52 and nRF53 multi-protocol wireless SoCs. nRF21540 key features and specifications: Supported wireless standards Bluetooth Low Energy (incl. Bluetooth mesh) Thread and Zigbee (802.15.4) Proprietary 2.4 GHz Output Power – Adjustable in small increments up to +21 dBm Receive Gain – +13 dB with 2.5 dB noise figure Antennas – 2x antenna ports for antenna diversity Host Interface – I/Os, SPI, or a combination Supply Voltage – 1.7 V to 3.6V Current consumption Tx tuned to +20 dBm: 115 mA […]

ONiO.zero offers a RISC-V Microcontroller that runs without battery

Energy harvesting has been an exciting area people have tried to venture into mostly because of the possible applications that can arise from it. Newly invented energy-harvesting technologies accompanying low-power computing systems have pushed the boundaries of where embedded systems can be deployed. The demand for an increase in connected applications which require an underlying embedded system, and as we know, all electronic devices require a power source of some sort. This power source, batteries in most cases, comes with an accompanying buck regulator of some sort that will tend to increase the BOM. Aside from the BOM rise from the usage of batteries, there is also the shelf life and environmental aspects. The Norwegian specialist ONiO has introduced the ONiO.zero to address those issues. Having no battery means fewer components and a smaller design, which can easily be integrated into a wide range of solutions – be it fabrics, jewelry, watches, wearable medical devices, livestock or building sensors.
