Amazon Web Services (AWS) provides cloud computing services to manage & store data from IoT Nodes over the Internet, but in some cases latency may be an issue, and Internet connectivity may not be reliable in all locations. AWS Greengrass provides a solution to those issues by running some of the IoT tasks within the local network in ARM or x86 edge gateways running Linux. You can still manage your devices from AWS cloud, but a Linux gateway running Greengrass Core runtime will be able to run AWS Lambda functions to perform tasks locally, keep device data in sync, and communicate with devices running AWS IoT Device SDK. Greengrass benefits include: Response to Local Events in Near Real-time Offline operation – Connected devices can operate with intermittent connectivity to the cloud, and synchronizes with AWS IoT once it is restored Secure Communication – AWS Greengrass authenticates and encrypts device data […]
Love to Code Board is Designed to Teach Coding via Paper Circuits, MakeCode Visual Programming Editor
Chibitronics has launched “Love to Code” board to enable beginners to try out programming without having to install software. The tiny board comes with a clip that designed for “paper circuits”, and can be programmed with either Microsoft MakeCode editor for visual programming, or the company’s online editor inspired from Arduino IDE. Love to Code board hardware (tentative) specifications: MCU – NXP Kinetis KL02 ARM Cortex M0+ @ 48 MHz with 32KB flash, 4KB RAM USB – 1x micro USB port used to power and program the board over a Y cable with micro USB and an audio jack to be connected to your smartphone as shown below) Expansion – 4x through holes for TXT, +5V, GND, and RGB, 6x programmable ports on clip to drive LED stickers, or used as switch / sensor inputs. Misc – Programming button, RGB LED The way it works is that you can first […]
Compulab’s Miniature “Bend & Fold” UCM-iMX7 System-on-Module Could Fit into a Watch
Many companies are still releasing NXP – soon to be Qualcomm – i.MX 6/7 system-on-modules, but I don’t cover all of them, since we have already many to choose from. But Compulab’s latest UCM-iMX7 SoM differentiates itself by it size, using the company’s “Ultra-compact Multilevel Module” (UCMM) technology, to pack NXP i.MX7 processor, 2GB RAM, 64 GB eMMC flash, and a wireless module into a 30 x 27 x 8 mm volume that could potentially fit into something as small as a watch. The picture above clearly shows how UCMM technology works with the module comprised of two rigid PCBs and one flexible layer routing signals between the two allowing to bend and fold the rigid parts together to form a vertical stack. The principle could be extended to more PCBs and flexible layers, sof for example you could have four PCBs with three flexible layers in future / custom […]
Android Things Developer Preview 4 Released with Google Assistant SDK Support
Earlier this month, Google released a preview of the Google Assistant SDK that works on boards running Debian like the Raspberry Pi 3, and even launched AIY Project Voice Kit for the later. You can now play with Google Assistant on Android Things as the company has just released Android Things Developer Preview 4 with support for Google Assistant SDK. The operating systems works on any Android Things certified devices, but the example instructions for Google Assistant API on Android Things also include steps to use Raspberry Pi 3 board together with AIY Projects Voice kit. The developer preview 4 also adds I2S to the peripheral I/O API and is demonstrated in the aforementioned example, and new hardware support with NXP i.MX7D based Pico Board equipped WiFi & Bluetooth, Ethernet, USB ports, an audio jack, and an I/O expansion port. Android Things DP4 also brings the ability for developers to […]
Christmann RECS|Box Atlas Quad Apalis Microserver Evaluation Kit Supports Four Toradex Apalis SoM
System-on-modules are normally used in low volume embedded systems, but they can also be used in microservers, for example to upgrade capacity as needed. Christmann informationstechnik + medien GmbH has developed a microserver evaluation kit taking up to 4 Toradex Apalis SoMs for example based on Nvidia Tegra K1 processor, and also offers full rack systems with up to 72 modules. Christmann RECS|Box Atlas Quad Apalis specifications: Modules – 4x Slots for Apalis SoM Connectivity – 1 GBit/s Compute Ethernet, 1 GBit/s Management Ethernet Video Output – 1x HDMI USB – 3x USB host ports, 1x micro USB port Misc – 5 Status LEDs for USB, communication, and serial console, 4x fan connectors, KWM switch, 5x temperature sensors, 6x current sensors, 1x voltage monitor, fan speed monitoring Power Supply – 12V via a 4-pin jack Dimensions – 300 x 145 x 68 mm The evaluation kit includes an Atlas board […]
Does That Crane or Drilling Rig Run mainline Linux?
Linux 4.11 has just been released, and as usual I looked into the changelog especially checking out work done on ARM architecture, and some newly supported SoCs or board. One line in the log caught my attention: “Liebherr (LWN) monitor 6 based on i.MX6 Quad, no idea what this is”. So I had a look, and Liebherr-Werk Nenzing GmbH is a swiss company specializing in construction machines and maritime cranes such as “crawler cranes, duty-cycle crawler cranes, as well as piling and drilling rigs”. The DTS file for LWN Monitor 6 shows an NXP i.MX 6Quad processor is used in a product with an LVDS display and various interfaces such as I2C, PWM, SPI, and so on. So it could be some kind of control panel for one or more of their equipment. After looking into some PDF documentation, we can see on page 10 that the company mentions Litronic […]
Linux 4.11 Release – Main Changes, ARM & MIPS Architecture
Linus Torvalds has just released Linux 4.11: So after that extra week with an rc8, things were pretty calm, and I’m much happier releasing a final 4.11 now. We still had various smaller fixes the last week, but nothing that made me go “hmm..”. Shortlog appended for people who want to peruse the details, but it’s a mix all over, with about half being drivers (networking dominates, but some sound fixlets too), with the rest being some arch updates, generic networking, and filesystem (nfs[d]) fixes. But it’s all really small, which is what I like to see the last week of the release cycle. And with this, the merge window is obviously open. I already have two pull request for 4.12 in my inbox, I expect that overnight I’ll get a lot more. Linux 4.10 added Virtual GPU support, perf c2c’ tool, improved writeback management, a faster initial WiFi connection […]
Wandboard QuadPLUS Development Board Gets i.MX 6QuadPlus Processor, 802.11ac WiFi and Bluetooth 4.1
The first Wandboard development boards launched in 2012 nearly 5 years ago based on Freescale i.MX6 Solo and Dual processor, with Wandboard Quad launched a few months later. The boards were fairly popular at the time due to their better specifications, and especially Freescale’s much better documentation and software compared to the competition such as Broadcom (Raspberry Pi) and Allwinner (Cubieboard). Since the boards are based on TechNexion EDM system-on-modules they could also be used by companies working on their own products based on the system-on-module. It’s also a good platform if you want to test various version of Android, because the company released Jelly Bean, Kitkat, Lollipop, and Marshmallow images for the boards, and I’m expecting a Lollipop version soon. However, albeit the company worked on other NXP boards such as PICO-IM6UL Android Things, there had not been any hardware upgrade for Wandboard for nearly 4 years, but last […]
