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

LoDev S76S

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 Expansion – 2x 20-pin unpopulated headers with I2C, SPI, UART, …

MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

MT3620 Mini Dev 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 802.11 a/b/g/n WiFi 1T1R with main and aux PCB antennas, …

HiFive1 Rev B Board Gets FE310-G002 RISC-V Processor, WiFi & Bluetooth Module

HiFive1 Rev B

SiFive launched what may have been the very first RISC-V development board in 2016 thanks to their HiFive1 Arduino compatible board powered by Freedom E310 (FE310) open source RISC-V processor. The company has now launched an upgrade version of the processor and board. Meet FE310-G002 processor and HiFive1 Rev B development board. HiFive1 Rev B development board specifications with new features highlighted in bold or stricken-through: MCU – SiFive Freedom E310-G0002 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 32 Mbit SPI flash (was 128 Mbit in the first version) Connectivity – ESP32-SOLO-1 WiFi & Bluetooth module I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages –  3.3V or 5V supported; note: bidirectional level shifters removed so FE310-G002 can drive the I/O pins directly at 3.3V only. USB – 1x micro USB port for power, programming and debugging (via Segger J-Link) Power …

NVIDIA Introduces $99 Jetson Nano Developer Kit

Jetson Nano

NVIDIA Tegra X1 octa-core Arm processor with a 256-core Maxwell GPU was introduced in 2015. The processor powers the popular NVIDIA Shield Android TV box, and is found in Jetson TX1 development board which still costs $500 and is approaching end-of-life. The company has now introduced a much cheaper board with Jetson Nano Developer Kit offered for just $99. It’s not exactly powered by Tegra X1 however, but instead what appears to be a cost-down version of the processor with four Arm Cortex-A57 cores clocked at 1.43 GHz and a 128-core Maxwell GPU. Jetson Nano developer kit specifications: Jetson Nano CPU Module 128-core Maxwell GPU Quad-core Arm A57 processor @ 1.43 GHz System Memory  – 4GB 64-bit LPDDR4 @ 25.6 GB/s Storage  – microSD card slot (devkit) or 16GB eMMC flash (production) Video Encode – 4K @ 30 | 4x 1080p @ 30 | 9x 720p @ 30 (H.264/H.265) Video Decode – 4K @ 60 | 2x 4K @ 30 …

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

Seco SBC-C43

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 flash, wired and wireless connectivity, HDMI 2.0 input and output, …

GRiSP 2 Board Targets Embedded Erlang & Elixir Development (Crowdfunding)

Erlang is described as a programming language used to build massively scalable soft real-time systems with requirements on high availability, and used in telecoms, banking, e-commerce, computer telephony and instant messaging. Elixir is a dynamic, functional language designed for building scalable and maintainable applications that leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems. Elixir is used in many types of applications from higher-level web development to the embedded software domain, and Peer Stritzinger designed GRiSP board especially for the latter in 2017. He’s now back with GRiSP 2 featuring an NXP i.MX 6ULL SoM running Linux and RTEMS (Real-Time Executive for Multiprocessor Systems) RTOS.

FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

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 the potential to grant bad actors access to your screen …
