OpenRemote fully open-source IoT platform targets OEMs and DIY projects

OpenRemote claims to be a 100% open-source IoT platform suitable for DIYs as well as OEMs. The asset management platform can help with the tracking of vehicle fleets, energy systems, or crowds, help to build smart cities, smart buildings, smart airports, and more. While most cloud IoT platforms rely on open-source tools, the software hosted on the providers’ servers is usually closed-source as we’ve seen in our comparison between Microsoft Azure IoT, Balena, and Particle, but OpenRemote is different will the full stack being released under an AGPLv3 open source license. OpenRemote 3.0 software is comprised of four main blocks: The Frontend is comprised of Consoles (native iOS and Android apps), Web components and Templates, as well as a System Administration interface used to create dashboards and control panels. Manager – headless Java application to capture the current asset states and includes Asset Management, State & Historical Data, Event Processing […]

ClusBerry Rack houses up to four hot-swappable Raspberry Pi CM4 modules

TECHBASE ClusBerry Rack supports up to four Raspberry Pi CM4 based modules which can be added and removed on the fly thanks to a lockable mechanism that reminds me of hot-swappable drives found in NAS. Using the same ClusBerry I/O mainboards as found in the earlier ClusBerry 9500-CM4 and ClusBerry-2M industrial systems, each Raspberry Pi Compute Module 4 inside the ClusBerry Rack offer one Gigabit Ethernet port, one USB host, one micro USB service port, and an RS-232/485 serial port. TECHBASE is not the best company when it comes to describing its products, possibly because those are customizable, and in this case, they don’t show the other side of the enclosure with all ports… But based on the PDF we’ve received, you should be able to create a system with four modules offering the following features each: Optional video output – HDMI Networking – 1x Gigabit Ethernet port (option for […]

Combining OSTree and SW Containers for reliable IoT Device updates

CNXSoft: This is a guest post by Drew Moseley, Technical Solutions Architect at Toradex, explaining how the company updates Linux IoT devices firmware with OSTree (aka libostree) open-source operating system build and deployment tool, as well as Docker software containers. Every day more and more connected devices are being brought to market and estimates for the total size of the Internet of Things (IoT) market are as high as $1.5 trillion by 2027. Gas pumps, medical devices, and point of sale systems are increasingly connected, making it virtually impossible to avoid interacting with these devices, even for complete Luddites. In the home, devices such as power meters, light switches, and security cameras are commonly internet-enabled allowing for smart home functionality. The level of complexity in the software for these devices increases with the functionality, and the number of devices with software defects in the field is growing. In many cases, […]

ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure. But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes. The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement: SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash. Storage – 2x M.2 slots for NVMe SSDs Video Output – 2x HDMI 2.0 ports Connectivity 4x Gigabit Ethernet […]

Use Scheme functional programming language with LambdaChip Alonzo STM32 board

LambdaChip Alonzo STM32 Scheme functional programming

Most MCU-based embedded systems come with firmware programmed with assembler, C, and/or C++. But as referenced in a paper published in 2000 entitled ” Point of view: Lisp as an alternative to Java“, functional programming languages like Lisp or Scheme may lead to shorter development times compared to C/C++ or Java. That’s with this idea in mind that LambdaChip was created. It is a lightweight, open-source virtual machine designed to run on embedded systems with limited resources, for instance, an 80MHz microcontroller with 50KB RAM, and programmable with Scheme multi-paradigm programming language, a dialect of Lisp widely used for functional programming research and teaching. The company behind the project, also called LambdaChip, has just created its own hardware with LambdaChip Alonzo, an STM32 Cortex-M4 development board with 512KB flash, 128KB RAM, and that also comes with Bluetooth LE connectivity. LambdaChip Alonzo board specifications: MCU – STMicro STM32F411CEU6 Arm Cortex-M4 MCU […]

NVIDIA Introduces Jetson Xavier NX Developer Kit, and Cloud-Native Support

NVIDIA Jetson Xavier NX SoM was launched last month for $459. But while some third-party carrier boards were also announced at the time, the company had yet to offer Jetson Xavier NX Developer Kit as they did for Jetson Nano. But as GTC 2020 conference is now taking place in the kitchen of Jensen Huang, NVIDIA CEO, the company had plenty to announce including Jetson Xavier NX Developer Kit as well as “Cloud-Native” support for all Jetson boards and modules. NVIDIA Jetson Xavier NX Developer Kit Specifications: CPU – 6-core NVIDIA Carmel ARMv8.2 64-bit processor with 6 MB L2 + 4 MB L3 cache GPU – NVIDIA Volta architecture with 384 NVIDIA CUDA cores and 48 Tensor cores Accelerators 2x NVDLA Engines 7-Way VLIW Vision Processor Memory – 8 GB 128-bit LPDDR4x 51.2GB/s Storage – MicroSD slot, M.2 Key M socket for NVMe SSD Video Output – HDMI and DisplayPort […]

DEVICE.FARM Generates Raspbian/Armbian Docker Images for about 100 Arm Linux SBCs

Last year, I reviewed BalenaOS and BalenaCloud on Raspberry Pi CM3L based BalenaFin hardware. The solution generates OS images with docker support in order to easily manage and update a fleet of devices remotely over a web interface or client program. Balena.io supports over 60 boards either officially, or thanks to the work of the community, but Pavel Burgr is developing an alternative with DEVICE.FARM supporting close to 100 Arm SBC’s including Raspberry Pi boards, and most Armbian supported Arm SBC’s. DEVICE.FARM is still beta, but the MVP (Minimum Viable Product) version of the website provides: Customized images for supported boards (currently 94 boards) Preinstalled docker Secure remote access to the device’s docker end-point Secure remote access to the device’s services exposed by containers This is functional, but bugs are likely, and documentation still needs to be finalized. I don’t have a board with me, but I tried to generate […]
