Beelink Expand X USB dock turns your phone into a computer

Beelink is better known for its Intel mini PCs, so the first time I saw Beelink Expand X I thought it was a mini PC somehow fitted with a smartphone stand… But instead, it’s a USB dock for your mobile phone or tablet, that comes with a foldable stand to use your smartphone into a computer by connecting it to a monitor, USB keyboard & mouse, and maybe throw a USB hard drive in the mix to complete your setup. Beelink Expand X specifications: Video Output – 1x HDMI port up to 4K UHD resolution USB 1x USB Type -C input port to connect to the host device (data, video, audio) 1x USB Type-C port for power/charging 2x USB 2.0 host ports 1x micro USB port to connect a PC Mode switch button Foldable stand for smartphone or tablet Dimensions – 120mm (length folded) x 65 x 13 mm (Full […]

NXP i.MX 8M Plus 2.5-inch Pico-ITX SBC supports UIO40-Express expansion modules

With NXP i.MX 8M Plus AI processor nearing mass production, we’ve seen many companies introduce i.MX 8M Plus systems-on-module at Embedded World 2021. But as one would come to expect, there should also be single board computers based on the new processor, and Advantech has unveiled the RSB-3720 2.5-inch SBC (aka Pico-ITX SBC) compatible with the company’s UIO40-Express expansion boards. RSB-3720 specifications: SoC – NXP i.MX8M Plus dual or quad-core Arm Cortex-A53 processor up to 1.8GHz (1.6 GHz for industrial temperature range) with Cortex-M7 real-time core, Vivante GC7000UL 3D GPU, 1080p60 H.265/H.264/VP9 decoder, 1080p60 H.265/H.264 encoder, 2.3 TOP/s Neural Network Accelerator System Memory – 4GB or 6GB LPDDR4 4000MT/s Storage – 16 GB eMMC Flash for OS, 8 MB QSPI NOR Flash for board information, microSD socket Video Output – HDMI 2.0a up to 3840 x 2160 at 30Hz Single or dual-channel 24 Bit LVDS with backlight power, 5/12V, Max.

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 […]

NXP unveils i.MX 8ULP Cortex-A35/M33 secure processors with optional Azure Sphere certification

NXP may have just unveiled plans for i.MX 9 processor family with Arm Ethos U65 microNPU, and advanced security using the company’s EdgeLock enclave, but NXP also introduced new members to its popular i.MX 8 series with i.MX 8ULP and i.MX 8ULP-CS (Cloud Secured) processors. Both processors come with a mix of Cortex-A35 application processor(s) and Cortex-M33 real-time core, as well as Energy Flex low-power architecture and EdgeLock secure enclave, but i.MX 8ULP-CS includes Microsoft Pluton for secure cloud connectivity and lacks 2D/3D graphics and the HiFi 4 audio DSP. NXP i.MX 8ULP and 8ULP-CS key features and specifications: CPU i.MX 8ULP – Up to two Arm Cortex-A35 @ 1.0 GHz and Arm Cortex-M33 @ 216 MHz, i.MX 8ULP-CS – One Arm Cortex-A35 @ 1.0 GHz and Arm Cortex-M33 @ 216 MHz GPU (i.MX 8ULP only) – 2D GPU, and 3D GPU with support for OpenGL ES 3.1, OpenCLTM, Vulkan […]

Edge AI video processing system combines SocioNext SC2000 4K camera SoC with Hailo-8 AI accelerator

We’ve previously written about Hailo-8 AI accelerator delivering up to 26 TOPS at low power (3 TOPS per watt), and found in AI edge systems such as Foxconn BOXiedge server powered by a Socionext SynQuacer SC2A11 24x Cortex-A53 cores SoC and capable of analyzing up to 20 streaming camera feeds in real-time for video analytics. Leopard Imaging has now created a much more compact Edge AI processing solution with EdgeTuring based on Hailo-8 M.2 card and Socionext SC2000 4K camera SoC, and designed for low-power video analytics. EdgeTuring features and specifications: Camera SoC / Image Processor – Socionext SC2000 quad-core Cortex-A7 processor @ 650MHz with 4Kp30 H.265/H.264 encoder, up to 1.2 Gigapixel per second processing, LPDDR-3 memory (PoP) AI Module – Hailo-8 M.2 Module for up to 26 TOPS Camera Dual camera but only one sensor works for AI Sensors – 2x Sony IMX477 CMOS Image Sensor, diagonal 7.857 mm […]

QuickLogic’s Hearable Reference Design enables Alexa Voice-Initiated Devices

Working with QuickLogic's Smart Hearable Reference Design

Last year we saw QuickFeather board featuring EOS S3 Cortex-M4F MCU with embedded FPGA, which was a crowdfunding project. This year the company has launched its smart hearable reference design based on a similar processor by QuickLogic. The device is dedicated to “Voice-Initiated, Hands-Free, Alexa Built-In Devices with Close-Talk Support.” QuickLogic’s smart hearable reference design is based on the company’s Open Reconfigurable Computing (QORC) which supports a complete open-source set of development options for the MCU and FPGA devices. It is also built on the EOS S3 Voice Processor and the QuickFeather open source development kit. This can enhance the user experience with a longer battery life of the device. The EOS S3 Arm Cortex- M4 processor features Low Power Sound Detection (LPSD) technology along with DSP Concepts’ TalkTo noise suppression and beamforming technology for the directional transmission of signals. It also comes with Alexa Wake Word engine technology, an […]

ANNKE CZ400 AI security camera review – Part 1: Specs, unboxing and teardown

We’re starting to see more and more security cameras with built-in AI features such as Reolink RLC-810A 4K camera with people & vehicle detection or the lower cost Vacom Cam Full HD camera with person detection only, which I have not reviewed yet due to some technical issues. I would not buy a camera without AI now as such features greatly reduce false positives. Another model has now come my way with ANNKE CZ400 (aka I91BK) 2K security camera that comes with even more advanced AI-accelerated computer vision features with not only face detection, but also intrusion detection, line crossing detection, region entrance detection, region exiting detection, object removal detection, unattended baggage detection, and audio exception detection. In this first part of the review, we’ll check the specifications, the content of the package with an unboxing, as well as a partial teardown that is needed to install a microSD card. […]
