Turing Smart Screen – A low-cost 3.5-inch USB Type-C information display

“Turing Smart Screen” is a low-cost 3.5-inch USB-C display that connects to systems with a USB port, and works with Windows, Linux (including Raspberry Pi), MacOS, and other operating systems that support Python3. But contrary to my initial assumptions, it does not exactly act as a second monitor, and instead, it is an information display, originally designed to show resource utilization, e.g. CPU and memory usage, in Windows, and controlled through commands send to the USB port. Turing Smart Screen specifications: 3.5-inch IPS display with 480×320 resolution, portrait and landscape support MCU – WCH CH552T 8-bit E8051 core MCU for USB devices Host interface – USB Type-C interface Auto start on power on Dimensions Product: 85 x 55 x 8 mm Display area: 74 x 49 mm The manufacturer says it works with Windows only using its own software, and not AIDA64. The Windows software features functions to change the […]

Khadas VIM4 Review – Part 1: Unboxing, kit assembly, and first boot with OOWOW

Khadas VIM4 is a compact Amlogic A311D2 octa-core Cortex-A73/A53 SBC with 8GB RAM, HDMI input and output, WiFI 6 connectivity, and more. You can check our earlier post for the full specifications. The good news is that it will officially launch on May 10. I’ve also just received a Khadas VIM4 review sample today together with accessories. Today, I’ll start by checking out the board, assembling the kit, and trying out OOWOW services to boot OS from the cloud, before testing available operating systems in more detail in the second part of Khadas VIM4 review a little later. Khadas VIM4 kit unboxing I received everything in a blank cardboard package with several small packages inside. Besides Khadas VIM4 SBC, we’ve got a plastic + metal enclosure with screws and screwdriver, two antennas for WiFi and Bluetooth, a USB Type-C power supply, a USB-C cable, an M.2 expansion board, a short […]

Axzez Interceptor carrier board for RPi CM4 gets 8-port PoE+ board

The features-rich Axzez Interceptor carrier board for Raspberry Pi CM4 has gotten the Interceptor PoE board with eight PoE+ ports for connecting up to sixteen PoE IP cameras making it usable as a network video recorder. We first wrote about the Interceptor last January noting its impressive I/O capabilities with five SATA ports, four Gigabit Ethernet, two HDMI ports, RS-485 terminal block, and more. It also had two 40-pin FFC connectors “for future expansion”. Those connectors have now found a “meaning to life” with the Interceptor PoE board, as up to two can be connected to the FFC connectors. Some of the features of the new Interceptor PoE Board include: 8x fast PoE+ ethernet ports IEEE 802.3AF-2003 and 802.3AT-2009 compliance Each port has activity/link and status LEDs Input voltage range – 44-57V Optional 48V power boost that can support up to two Interceptor PoE+ boards (Powered from 12V ATX power […]

Morefine S500+ Review – An AMD Ryzen 7 5700U mini PC tested with Windows 11, Ubuntu 20.04

Morefine has recently released their S500+ series of mini PC series which features models with either a Zen 2 or Zen 3 AMD mobile processor. Morefine kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu. Morefine S500+ Hardware Overview The S500+ physically consists of a 149 x 145 x 40mm (5.87 x 5.71 x 1.57 inches) square metal case with a plastic top. As an actively cooled mini PC, it is available with either an AMD Zen 2 or Zen 3 mobile processor. The review model came with AMD’s 7 nm Zen 2 Ryzen 7 5700U Lucienne processor which is an eight-core 16-thread 1.8 GHz mobile processor boosting to 4.3 GHz with Radeon Graphics. The front panel has a power button, a light to indicate power, two USB 3.1 ports, and a Type-C USB 3.1 port with Alternate Mode. The rear panel includes a […]

StarFive releases Perf tool for highest performance RISC-V IP Dubhe (Sponsored)

As a StarFive Technology in-house developed RISC-V 64-bit ultra-high-performance core, Dubhe showcases the best performance RISC-V CPU core IP yet. It utilizes the latest RISC-V instruction set which includes RV64GC, bit operation extension (B), vector extension (V) V1.0, and hypervisor extension H (Hypervisor), making it ideal for high-performance computing. To pair with the Dubhe performance core, StarFive is now releasing “StarFive Perf Performance Profiling Tool”. StarFive has made Perf compatible with the hardware performance monitor (HPM) and micro-architecture events at the hardware level. Perf provides a reliable performance verification platform that not only facilitates customers to further discuss the Dubhe technical specifications but also accelerates the implementation of high-performance applications with RISC-V processors. Perf is an open-source and Linux-based performance analyzing tool capable of providing performance monitoring of the hardware events, tracepoints, firmware events, and dynamic probes. With the Perf profiling tool, we can monitor the performance of the predefined […]

NVIDIA NVDLA AI accelerator driver submitted to mainline Linux

A large patchset has been submitted to mainline Linux for NVIDIA NVDLA AI accelerator Direct Rendering Manager (DRM) driver, accompanied by an open-source user mode driver. The NVDLA (NVIDIA Deep Learning Accelerator) can be found in recent Jetson modules such as Jetson AGX Xavier and Jetson AGX Orin, and since NVDLA was made open-source hardware in 2017, it can also be integrated into third-party SoCs such as StarFive JH7100 Vision SoC and Allwinner V831 processor. I actually assumed everything was open-source already since we were told that NVDLA was a “complete solution with Verilog and C-model for the chip, Linux drivers, test suites, kernel- and user-mode software, and software development tools all available on Github’s NVDLA account.” and the inference compiler was open-sourced in September 2019. But apparently not, as developer Cai Huoqing submitted a patchset with 23 files changed, 13243 insertions, and the following short description: The NVIDIA Deep […]
