NODE Mini Server V2 is a Raspberry Pi Based Storage Server for the Decentralized Web

We’ve previously covered networked hard drive enclosures with Ethernet and/or WiFi running OpenWrt or Ubuntu that allows you to easily and fairly cheaply connect SATA drives to your local network with models such as Blueendless X3. NODE has done something similar with a DIY project featuring a Raspberry Pi 3 Model B+. NODE Mini Server V2 connects the popular SBC to a 2.5″ SATA hard drive over USB and is designed to build out the physical infrastructure for the decentralized web (e.g. IPFS) that would allow users to replace remote servers with nodes that they themselves own and operate. Having said that nothing would prevent you from using this as a simple NAS although performance will not be as optimal as the aforementioned products due to the lack of SATA or USB 3.0 interface, as well as having “Gigabit” Ethernet limited to 300 Mbps. Having said that the design could […]

Xilinx Arm FPGA, Snapdragon SoM’s, and Wandboard SBC Field Trip to Space

SpaceX Starlink Satellites Falcon Rocket

Most embedded systems are used here on planet earth, but some do take off heading for space, and this week I come accross two separate projects leveraging Arm processors and FPGAs, as well as Ubuntu/ROS and Android operating systems: SpaceX Starlink communication satellites and Astrobee robots roaming in the international space station (ISS) SpaceX Starlink Satellites with Xilinx Ultrascale+ Arm + FPGA SoC SpaceX is about to launch a cloud of 60 Starlink communication satellites that aims to provide internet communication anywhere in the world. That’s just a start as eventually the plan is to get up to 12,000 of those satellites. Usually, we would not know many technical details about the satellites, but as one reader pointed out (Thanks Lawrence!), a Reddit thread about the launch, also pointed to a NASA document revealing the satellites are powered by Xilinx Ultrascale+ quad core Cortex-A53 processor with FPGA fabric. Milestone 2 […]

Maixduino SBC Combines RISC-V AI, Arduino Form Factor, and ESP32 Wireless Module

Last year RISC-V cores made it into low-cost hardware with neural network and audio accelerator to speed up artificial intelligence workloads at the edge such as object recognition, and speech processing. More precisely, Kendryte K210 dual-core RISC-V processor was found in Sipeed MAIX modules and boards going for $5 and up. Since then a few other variants and kits have been made available including Seeed Studio Grove AI HAT that works connected to a Raspberry Pi or in standalone mode. Seeed Studio has now released another board with Kendryte K210 RISC-V AI processor, but based on Arduino UNO form factor and equipped with an ESP32 module for WiFi and Bluetooth connectivity. Meet Sipeed Maixduino SBC. Sipeed Maixduino specifications: AI Module – Sipeed M1 with Kendryte K210 dual-core RISC-V processor @ 600 MHz, KPU Convolutional Neural Network (CNN) hardware accelerator, APU audio hardware accelerator, 8 MB general purpose SRAM including 5.9MB […]

299 Euros Motorola One Vision Smartphone Features Samsung Exynos 9609 SoC

I find most new phones’ announcements rather boring, but Motorola One Vision is somewhat interesting as it’s one of the rare non-Samsung phones to features an Exynos processor, more specifically Exynos 9609 which has not been seen in any other smartphones so far. Its other highlight is the 48MP camera sensor normally found in premium phones, and not in a 299 Euros device. Motorola One Vision specifications: SoC – Samsung Exynos 7609 octa-core processor with 4x Cortex-A73 @ 2.2GHz, 4x Cortex-A53 @ 1.6GHz, and Arm Mali G72MP3 System Memory – 4GB LPDDR4 Storage – 128GB internal storage, microSD card slot Display – 6.3″ LCD touch screen display with 2520 x 1080 resolution (21:9 aspect ratio) Camera 48MP rear camera with OIS based on IMX586 sensor 5MP Depth sensor 25MP front-facing camera Audio – 3.5mm headphone jack Wireless connectivity Cellular – 1x nanoSIM + 1x nanoSIM/microSD hybrid 802.11ac Wave 2 Wi-Fi […]

Arduino SIM for Arduino IoT Cloud Includes 10 MB of Free Data

Arduino SIM Card Arduino MKR GSM 1400 board

I’ve been using Hologram developer SIM card for cellular IoT hardware reviews since it’s really great for evaluation as the company offers 1MB of data for free monthly. It’s supposed to work worldwide, but recently I discovered that while 3G worked fine in Thailand, the card would not support NB-IoT just yet. More companies are now offering this type of global cellular IoT SIM cards such as Twilio or SORACOM, and Arduino is now joining the fray by offering the Arduino SIM card specifically designed to connect to Arduino IoT cloud. The Arduino SIM card currently works with Arduino MKR GSM 1400 board only, and Arm Pelion Connectivity Management provides the cellular service with a global roaming profile than enables connectivity in over 100 countries at a low cost. The first 90 days are actually free if you use less than 10MB of data, after which the price is 5MB […]

Google Glass Enterprise Edition v2 Features Snapdragon XR1 Processor

To be honest, I was pretty happy when it was clear that smart glasses for the consumer market would not take off, and I would be living in a better, smart glasses-free, world. But I also reckoned that those could have use in professional settings, and Google Glass Enterprise edition was first spotted in 2015 with an Atom processor. The company has now launched an upgraded model with Google Glass Enterprise Edition v2 powered by Qualcomm Snapdragon XR1 eXtended reality (XR) platform. Google Glass Enterprise Edition v2 specifications: SoC – Qualcomm Snapdragon XR1 quad-core Kryo processor @ 1.7GHz with Adreno GPU, Qualcomm AI Engine for on-device processing; 10nm manufacturing process System Memory – 3GB LPDDR4 Storage – 32GB eMMC flash storage Display – 640×360 Optical Display Module Audio out – Mono Speaker, USB audio, BT audio Microphones – 3 beam-forming microphones Camera – 8MP, 80 DFOV Connectivity – Wi-Fi 5 […]
