Arrow Embedded To Go Free Online Conference, and 3,000 Development Boards Giveaway

With the coronavirus outbreak on-going, many events are either canceled or moving online. Arrow Electronics has now announced what appears to be a completely new online event. Embedded To Go virtual technology exhibition for embedded systems will take place on April 1-3, 2020, and offer technical presentations, information on newly launched technology, and access to Arrow’s sales and engineering teams. The event will entirely free to attend, and you can register online today with a company’s email address. The event will start in about 10 days by so far the virtual “booth map”, “supplier guide” and “lecture area” are inaccessible. We only know what the event should consist of thanks to an article on EENew Embedded: Technical presentation webinars will be hosted by leading suppliers covering AI, IoT and Edge computing, precision measurement, high-performance computing, intelligent condition-based monitoring, and other technological subjects. Information will also be available in the form […]

MikroElektronika Launches Fusion for ARM & EasyPic MCU Development Boards

During Embedded World 2020 (EW2020), some companies withdrew their presence, while some were at the event. MikroElektronika presented several new boards and among them Fusion for ARM v8 and EasyPic v8 development boards. While we already wrote about Fusion fo TIVA, we haven’t covered any EasyPic board yet. Development boards from MikroElektronika allow rapid prototyping in the most efficient and effortless way. Fusion for ARM v8 Fusion for ARM v8 belongs to the Fusion family of development boards. It has integrated the world’s first embedded debugger/programmer over WiFi, while the CODEGRIP WiFi license is available as an add-on feature. The board is designed to be used in almost every environment retaining full debugging and programming access. The CODEGRIP currently supports more than 1600 microcontrollers from different vendors. The Fusion board integrates a new MCU card standard. It is a low profile standard where sockets consist of two connectors (male/female) which […]

Arm Introduces Cortex-M55 MCU Core, Arm Ethos-U55 microNPU for Cortex-M Microcontrollers

Artificial Intelligence and the Internet of Things often go hand in hand with AIoT being a new buzz word that came up last year or so. But for AIoT to scale we need ultra-low-cost, low-power solutions capable of doing inference at the sensor node level, and this is only possible with microcontrollers. To achieve this goal, Arm has just unveiled the Arm Cortex-M55 microcontroller core optimized for artificial intelligence workloads that delivers up to a 15x uplift in ML performance and a 5x uplift in DSP performance with greater efficiency, as well as Ethos-U55 microNPU designed for Cortex-M microcontrollers that need even more AI performance (up to 480 times faster), while consuming as little power as possible. Arm Cortex-M55 Key features and specifications: Architecture – Armv8.1-M Bus interface – AMBA 5 AXI5 64-bit master (compatible to AXI4 IPs) Pipeline – 4-stage (for main integer pipeline) Security – Arm TrustZone technology […]

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, […]

Some Interesting Talks from FOSDEM 2020 Schedule

We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]

BOKRA NXP LPC824 and Nordic nRF52832 powered MCU Modules Follow MikroBUS Form Factor

We first wrote about MikroElectronika MikroBUS socket in 2015 while covering an SBC which featured one MikroBUS socket supporting one of the 150 Click boards available at the time. There are now over 700 Click boards to choose from, with the tiny modules offering motor drivers, buttons, short-range connectivity, UART and other interfaces, as well as various sensors. But BOKRA had another idea: developing MCU based systems-on-module following MikroBUS form factor. BOKRA LPC824 Lite module The first of those modules is BOKRA LPC824 Lite with the following specifications: MCU – NXP LPC824M201JHI33 Arm Cortex-M0+ microcontroller @ 30 MHz with 32KB Flash Memory, 8 KB RAM I/O MikroBUS headers with SPI, I2C, UART, PWM, GPIOs 10-pin “Serial” header 4-pin I2C Grove connector for Seeed Studio I2C Grove modules Debugging interface – SWD Misc – Reset button, power LED, 2x user LEDs Power Supply – 5V/500mA via MIC5528 regulator Dimensions – 28.6 […]
