LoDev S76S Board Combines STM32, LoRa and Arm Mbed Support (Crowdfunding)

There are already plenty of low power boards with a LoRa radio, but Ronoth offers another option with their tiny LoDev S76S LoRa development board featuring AcSip S76S SiP (system-in-package) with STMicro STM32L073 microcontroller, a Semtech SX1276 LoRa radio, and other components. While most hobbyist LoRa boards are designed to be programmed with the Arduino IDE, LoDev S76S is instead compatible with Arm Mbed. LoDev S76S board specifications: SiP – AcSip S76S system-in-package with STMicro STM32L073 Arm Cortex-M0+ microcontroller @ 48 MHz with 192 kB flash, 20 kB RAM Semtech SX1276 chip supporting global 863MHz ~ 928MHz ISM Bands RF front-end LoRa Connectivity Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +20 dBm Range – up to 15 km coverage in suburban areas and up to 5 km coverage in urban areas SMA antenna connector USB – 1x micro USB port for programming and power […]

MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

Announced nearly one year ago, Microsoft Azure Sphere is an ecosystem comprised of Azure MCUs with Microsoft Pluton Security System, Linux based Azure Sphere OS, and a secure cloud service called Azure Sphere Security Service. The first official Azure development board – MT3620 Development Board for Azure Sphere – was launched last year for $84.95. The kit may not have attracted a large number of developers, so there’s now a cheaper version – MT3620 Mini Dev board – going for $34.90 on Seeed Studio. Note that’s a pre-order and shipping is scheduled for May 13, 2019. MT3620 Mini dev board specifications: CPU Module – AI-Link WF-M620-RSA1 module with Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz with 4MB SRAM, dual core Arm Cortex-M4F real-time core @ 200 MHz with 64KB RAM, Pluton security sub-system, and WiFi. Storage – 2x 8MB dual channel quad SPI (TBC) Connectivity – Dual band […]

Cypress PSoC 64 Microcontrollers Target Secure IoT Applications

If you are like me, you probably don’t remember, but back in 2017 Arm announced the Platform Security Architecture (PSA) that defines a set of requirements to secure low cost Internet of Things devices. There’s now at least one PSA compliant microcontroller, as Cypress Semiconductor introduced their PSoC 64 Secure MCU at Embedded World 2019 last month. The press release claims that PSoC 64 MCU family is one of “the first Arm Cortex-M processors to be certified as Level 1 compliant within the Arm Platform Security Architecture (PSA) certification scheme, PSA Certified, utilizing a secure Trusted Firmware-M (TF-M) implementation integrated into the Arm Mbed OS open-source embedded operating system”. PSoC 64 secure MCU key features and specifications: Arm Cortex-M4F core with 22‑µA/MHz active power consumption Optional Arm Cortex-M0+ core with 15‑µA/MHz power consumption System Memory – 160KB to 1MB SRAM Storage – 512KB to 2MB flash Security HW Cryptography – […]

Seco SBC-C43 SBC Features NXP i.MX 8 QuadMax Processor, 8GB RAM

When NXP unveiled their first 64-bit i.MX processors in 2016, we had three families: i.MX 8 Cortex-A72/A53 for high performance, i.MX 8M Cortex-A53 for audio/video application, and i.MX 8X Cortex-A53 for low power applications. Most of the designs we’ve seen so far are based on i.MX 8M family, and we’ve seen few hardware platforms based on the top of the line i.MX 8 QuadMax SoC with two Arm Cortex-A72 cores, four Cortex-A53 cores, two Cortex-M4F real-time cores, and two GC7000XS/VX GPUs. We did cover several modules based on i.MX 8 QuadMax processor including Advantech ROM-7720 Qseven 2.1 Computer-on-Module, Toradex Apalis i.MX 8 CoM, and Congatec conga-SMX8 SMARC 2.0 SoM among others, but AFAICR I had yet to see an i.MX 8 QuadMax single board computer. So Seco SBC-C43 appears to be the first SBC powered by NXP’s most powerful i.MX 8 processor, coupled with up to 8GB DDR4, 32GB eMMC […]

Samsung ARTIK Product Line Discontinued

Everyday I read hundreds of articles trying to find something interesting to write on CNX Software blog, and one way I keep track of news is to subscribe to RSS feeds using Thunderbird. From time to time, feeds get broken due to updates making them fail RSS validation, and today I noticed Samsung ARTIK feed had stopped working, so I went to the website, and… Wait… What closure of ARTIK business? It turns out Samsung Electronics decided to shutdown their ARTIK product line in December 2018 as reported by Business Korea: Samsung Electronics will pull the plug on its ARTIK project in four years after starting to develop the internet of things (IoT) platform. … IT industry experts say that Samsung decided to halt the ARTIK project because of its poor results. Samsung wanted to build an IoT ecosystem and lead the IoT market through the ARTIK project but it […]

FOSSASIA 2019 Schedule – March 14-17

As its name implies, FOSSASIA is a Free and Open Source Software event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event. Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have […]

Kontron SMARC-sAL28 System-on-Module Supports ECC Memory, Up to 5 TSN Ethernet Ports

Many systems-on-module are equipped with one Gigabit Ethernet transceiver / PHY, but NXP LS1028A powered Kontron SMARC-sAL28 SoM is equipped with two Gigabit Ethernet PHY, and can optionally support up to 5 TSN-capable Gigabit Ethernet ports directly from the controller thanks one PCIe line that can be used as a QSGMII (Quad Serial Gigabit Media Independent Interface) port. Furthermore, the module comes with up to 4GB non-ECC or ECC memory. “What is TSN?” you may ask. It stands for “Time-Sensitive Networking“, provides distributed time synchronization and deterministic communication using standard Ethernet networks for applications such as distributed synchronized measurements, coordinated distributed data logging, next-generation computer numeric control machining, automotive networks, and more as explained on National Instruments website. But let’s go back to Kontron SMARC-sAL28 system-on-module with the hardware specifications: SoC – NXP LS1028A dual Arm Cortex A72 processor, 3D GPU System Memory – Up to 4GB DDR3L ECC or […]
