ClusterCTRL Stack Helps You Power and Cool up to 5 Raspberry Pi SBC’s

Building a small cluster of Raspberry Pi boards or/and other compact single board computers requires you to handle power and cooling issues, as it may not be practical to have one power supply per board, and since boards are close to each other heat may build up. There are already off-the-shelf solutions such as rackmounts for Raspberry Pi SBCs or carrier boards for multiple Raspberry Pi Compute Modules but more often they do take not take care of all issues like mounting, power, and cooling. ClusterCTRL Stack offers a solution that can power up to 5 Raspberry Pi SBC’s via a 12V/24V power supply and control up to two fans. If you could also 3D print an enclosure for your cluster in order to attach the fan. ClusterCTRL Stack is comprised of two boards with the following key features and specifications: Controller Board Power Input – 12-24V PSU. Power Output 20-pin header with 2x5V and 2xGND for each board. 1x …

BaHa Box Smart Automation Hub Features Allwinner H2+ or NXP i.MX 6ULL Processor (Crowdfunding)

Most devices on the market are designed with a single brand of processor, but for their BaHa Box smart automation hub, xPoint Products decided to offer either Allwinner H2+ or NXP i.MX 6ULL versions. Why is that? Easy: Allwinner H2+ processor provides a cheaper solution for the residential market, while NXP i.MX 6ULL wide temperature range makes it more suitable for commercial applications. Both versions of BaHa Box smart hub run Linux on 256MB RAM, and offers Ethernet, WiFi, and Bluetooth connectivity, with options for Zigbee and Z-Wave. The hub supports over 2,000 devices and can work either connected to the cloud, or “offline” without internet. BaHa Box specifications: SoC Residential-grade version – Allwinner H2+ quad-core Cortex-A7 processor Commerical-grade version – NXP i.MX 6ULL Cortex-A7 processor System Memory – 256MB DDR3 Storage MicroSD card slot Residential-grade version – 256KB flash Industrial-grade version – 256MB flash Connectivity 10/100M Ethernet, WiFi, and Bluetooth Optional Zigbee and Z-wave in “advanced” models.

Odyssey Blue J4105 Windows & Linux Mini PC Comes with a 128GB SSD, an Arduino Compatible MCU

We recently reviewed ODYSSEY-X86J4105 SBC by Seeed Studio with Windows 10, and installed it to the Re_Computer case to convert it into a mini PC. Besides being a standard Intel Gemini Lake SBC, the board also comes with an Arduino MCU and header, as well as a 40-pin I/O header so it can be an all-in-one Arduino development platform, or be used for advanced robotics projects. Both the board and case had to be purchased separately, and Windows 10 was pre-installed on the internal eMMC flash. But now, Seeed Studio has started to offer Odyssey Blue J4105 mini PC with ODYSSEY-X86J4105 SBC pre-installed into Re_Computer case and fitted with a 128GB SSD for increased storage capacity and better performance. Odyssey Blue J4105 mini PC specifications: SoC – Intel Celeron J4105 quad-core processor @ 1.5/2.5 GHz (Turbo) with 12EU Intel UHD Graphics 600 @ 250-750 MHz; 10W TDP System Memory – 8GB LPDDR4 RAM Storage 128GB M.2 SATA SSD Support for …

RAK2287 Mini PCIe LoRaWAN Concentrator Module Supports up to 500 Nodes per km2

RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm @ SF12, BW 125 kHz LoRaWAN® 1.0.2 compatible.

MEGA-RTD Raspberry Pi HAT Offers up to 64 Resistance Temperature Detectors (Crowdfunding)

Sequent Microsystems like to make stackable Raspberry Pi HATs. After their stackable 4-relay board allowing for up to 32 relays controlled by a Raspberry Pi board, the company has now launched MEGA-RTD 8-channel RTD Raspberry Pi HAT enabling up to 64 resistance temperature detectors via 8x MEGA RTD board stacked on top of a Raspberry Pi board. If you haven’t heard about this type of temperature sensors, we wrote a post explaining the advantages and drawbacks of resistance temperature detectors last year. Basically, those temperature sensors contain a resistor that changes resistance value as their temperature changes, and support much wider temperature ranges than traditional temperature sensors such as DHT22 while keeping a <0.1°C accuracy. The price of the sensors themselves is similar to traditional sensors, but the total price is more expensive since they require extra hardware to measure the resistance/voltage value. MEGA-RTD key features and specifications: MCU – STMicro STM32F030 Arm Cortex-M0 microcontroller handling I2C commands from Raspberry …

ThinkCentre M75n IoT Nano Desktop Features a 6W AMD Athlon Silver 3050e Processor

Earlier today, we wrote about AMD 3015e dual-core/quad-thread Zen processor with 6W TDP found in some upcoming education laptops from Lenovo. We also noted that two other recent 6W AMD processors had been introduced by the company AMD 3020e and AMD Athlon Silver 3050e. When looking for AMD 3020e I got ACER ASPIRE A314-22-A8ST 14″ laptop with 4GB RAM and 256GB SSD listed for 9,590 Baht ($309 inc. 7% VAT) – but out of stock – on several Thai websites, but after switching to a US VPN all product reference disappeared, except for Lenovo Ideapad 3 soon getting an AMD 3020e model. None of the laptops are available now, but at least that means AMD does not only target the education market with its 6W SKUs. But when I searched for AMD Athlon Silver 3050e platforms, I realized Lenovo made an announcement last June about ThinkCentre M75n IoT Nano Desktop designed for Internet of Things applications in manufacturing, retail, and …
