USB4 Specification Released, Up to 40 Gbps Data Transfer Rate Supported

USB4 Specification

USB 3.2 was announced about two years ago with speeds of up to 20 Gbps using existing USB 3.1 Gen 2 USB-C cables, but the USB Implementers Forum has done a bit work more and just released the USB4 specification allowing twice the speed at 40 Gbps. The USB4 architecture leverages the Thunderbolt protocol specification that was recently contributed by Intel Corporation to the USB Promoter Group, enables the faster data rate, as well as multiple simultaneous data and display protocols. Highlights of USB4 standard Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps certified cables Multiple data and display protocols that share the maximum aggregate bandwidth Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3 Up to 100 Watts power delivery Both USB 3.2 and USB4 require USB-C cables to make use of the maximum transfer rate, so traditional USB cables may fade away in the future. It may take a while before …

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

BOXER-8150AI

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 3.0 1x GbE LAN 1x COM Compact Size chassis The …

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

USB cable tester

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 data and charge a device much more slowly. Smart USB …

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 the air conditioner is set to 28°C, so that’s about …

Geniatech A683 is an ATSC 3.0 USB TV Tuner

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 with an ATSC 3.0 tuner, so an easier way is …
