AAEON Launches BOXER-8150AI Compact Embedded Box PC Features 8 USB 3.0 Ports

The new compact embedded solutions’ addition to the BOXER-8100AI family is specially designed for artificial intelligence (AI) support. According to its makers, AAEON, it has a configuration of eight USB 3.0 ports made available through four USB controllers chips. This makes it perfect for a wide range of computer vision applications, some of which are visual inspection, quality control, and facial recognition. Now, each USB chip controls a pair of USB 3.0 ports. By dedicating one chip to one pair of ports, each chip handles less data traffic overall. This also improves bandwidth from connected devices and allows the BOXER-8150AI to maximize speeds and framerates of AI image processing. The product is currently in stock and available for purchase on AAEON online store for $1,142.00. Key Features of BOXER-8150AI Nvidia TX2 Module HMP Dual Denver 2 + Quad ARM A57 8GB LPDDR4 32GB eMMC 5.1 HDMI 2.0 8x USB […]

$10 Is it me or is it is just USB? Board Quickly Tests your USB Cables

USB 2.0 and 1.1 cables are supposed to come with four signal: GND and 5V for power, and D-/D+ for data. Some chargers come with cables without the data cables. It may “work” for charging, but if for some reasons you decided to use that USB cable for tasks requiring data this won’t work, and you may not find out easily the reason at first. Importantly the data lines can also be used during charging to request more power from the host device, so if they are missing slower charging may ensue. You could always use a multimeter to check your cables, but “iUSB cable testers it me or is it just USB? ” board provides a simpler and faster solution by indicating which wires are connected in your cable with LEDs. The developer, named nerfhammer, separate cables with and without data lines as follows: Basic USB cables cannot transfer […]

Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white. Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast. There was an in-depth article written on a similar hub some time ago. Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is […]

New Raspberry Pi 4 VLI Firmware Lowers Temperature by 3-5°C

Raspberry Pi 4 VLI Firmware Idle Temperature

The other day I tested Raspberry Pi 4 with an heatsink since previous multi-threaded benchmarks clearly made the board throttle when running those without any cooling solution. The guys at the Raspberry Pi Foundation somehow noticed my post, and I received an email from Eben Upton explaining a new Raspberry Pi 4 VLI firmware had “some thermal optimizations that are not installed by default on early production units.” I did not understand VLI at first, but eventually understood this referred to the firmware for VIA VL805 PCIe USB 3.0 controller on the board. The Raspberry Pi Foundation provided me with a test version of the firmware, which they’ll release in the next few days, or weeks after testing is completed. Now if you’re going to test a platform that will throttle due to overheating, it’s very important you do so at constant room temperature. I work in a office where […]

MINIX NEO S1 & S2 Combine SSD and USB-C Hub into a Single Device

MINIX has sold accessories for mini PCs for a little while, and last year I wrote a short review for MINIX NEO C Plus USB-C adapter with dual HDMI output, Ethernet, USB ports, and microSD and SD card slots. The company is apparently about to launch two new USB-C hubs that come with built-in SSD storage. MINIX NEO S1 & S2 USB-C hub include respectively a 120GB and 240GB SSD, and while they are not yet listed on MINIX website, GearBest is offering the two new accessories for $84.99 and $97.99 with shipping scheduled for early July. MINIX NEO S1/S2 specifications: Storage – Built-in 120GB or 240GB SSD storage up to 415MB/s read speed and 400MB/s write speed Video Output – HDMI up to 4K @ 30Hz USB – 2x USB 3.0 ports, USB-C port for power delivery only, USB-C cable to connect to laptop, computer or board. Misc – […]

Geniatech A683 is an ATSC 3.0 USB TV Tuner

ATSC (Advanced Television Systems Committee) is the standard used in North American, and some other countries around the world such as South Korea, for digital terrestrial television that allows you to receive free-to-air or paid channels over an indoor or outdoor antenna. ATSC 3.0 is the very latest version of the standard with new features including “H.265/HEVC for video channels of up to 2160p 4K resolution at 120 frames per second, wide color gamut, high dynamic range, Dolby AC-4 and MPEG-H 3D Audio, datacasting capabilities, and more robust mobile television support” (Source: Wikipedia). The first deployments occurred in South Korea in May 2017, but it’s unclear where the US is at the moment, and it seems there were some broadcast tests in 2018, but not full deployments. Nevertheless, if you want to watch or record programs in ATSC 3.0 channels, you’ll need new hardware, and currently most TVs won’t ship […]

Silicon Motion SM3282 is a Single Chip Solution for Portable USB SSD Sticks

Portable USB SSD drives are nothing new, but they are usually implemented using a stand-alone SSD with its own SSD controller combined with a USB to SATA or PCIe bridge chip in order to interface the SSD drive with the host computer or board. Silicon Motion has recently unveiled SM3282 SSD controller that also comes with an on-chip USB 3.2 Gen 1 interface providing a complete single-chip hardware and software solution for portable USB SSD sticks. This should enable smaller and cheaper USB SSD drives. Some of the key features of the SM3282 controller include: Peak sequential read and write transfer speeds of over 400MB/sec Supports USB 3.2 Gen 1 type A and type C Crystal-less design for bill-of-materials cost savings Built-in 3.3V/2.5V/1.8V/1.2V voltage regulators Supports LED for indicating access status 68-pin QFN package Compatible with Windows 10, Mac OS 10.x and Linux kernel v2.4 and greater The chip also […]
