Rockchip RK3568-powered ASUS Tinker Board 3N is now available in three variants

The ASUS Tinker board 3 was first unveiled in April 2023 before being renamed as Tinker Board 3N later that year, and the three variants of the Rockchip RK3568 single board computer (SBC) are now available. The standard configuration is the Tinker Board 3N in the commercial temperature range, while the Tinker Board 3N Plus has the same features, except it can operate in the industrial temperature range (-40°C to 85°C). The Tinker Board 3N Lite is a cost-down version in the same form factor, but with a single gigabit Ethernet port without PoE support, no M.2 B-key socket for an NVMe SSD or 4G/5G cellular connectivity, no 16MB SPI flash, fewer serial interfaces, and no CAN Bus. You’ll find a comparison of the specifications for the three variants in the table below. Note the prices above are from Amazon with a 10% discount when applicable. ASUS provides support for […]

GEEKOM A7 review – Part 2: Windows 11 Pro tested in a compact AMD Ryzen 9 7940HS mini PC

We previously had a look at the hardware of the GEEKOM A7 with an unboxing and a teardown of the powerful AMD Ryzen 9 7940HS mini PC with 32GB DDR5, a 2TB NVMe SSD, four 4K-capable video outputs, and high-speed interfaces such as USB4 and 2.5GbE, as well as WiFi 6E and Bluetooth 5.3 wireless connectivity. We’ve now had time to test it with Windows 11 Pro in detail, so in the second part of the GEEKOM A7 review, we’ll report our experience with the mini PC including a software overview, features testing, various benchmarks, networking and storage performance testing, fan noise, power consumption, and more. Software overview and features testing The System->About window confirms the GEEKOM A7 mini PC is powered by an AMD Ryzen 9 7840HS processor with Radeon 780M graphics with 32GB RAM and runs Windows 11 Pro 23H2 build 22631.2861. That also means we only had […]

Microchip announces the PolarFire SoC Discovery Kit, a low-cost devkit for Linux and real-time applications

The SoC Discovery Kit is the latest addition to Microchip’s list of development kits for the PolarFire series. The series is the first SoC FPGA family powered by a deterministic, coherent RISC-V CPU cluster. They provide low power consumption, thermal efficiency, and defense-grade security for smart, networked systems. They also support a deterministic L2 memory system for Linux and real-time applications. Microchip launched the Icicle Kit for the PolarFire SoC in 2020 and it was followed by the Video and Imaging Kit which was intended for mid-bandwidth imaging and video applications. Now, Microchip has announced the Discovery Kit which is billed as a low-cost alternative to the Icicle. The Discovery Kit retains the full range of features needed for testing concepts quickly, developing firmware applications, and programming/debugging user code. According to Microchip, the kit will bring “a low-cost RISC-V and FPGA development for learning and rapid innovation” to new and […]

Android 15 Developer Preview released – What’s New?

Google has just released the first Android 15 Developer Preview with some improvements related to privacy and security, the addition of the partial screen sharing feature, camera and audio improvements, and some new performance optimization that developers can leverage when running games or other demanding applications. User privacy and security in Android 15 Android 15 features the latest version of the Privacy Sandbox on Android to improve user privacy while enabling personalized advertising experiences for mobile apps, the Heatlth Connect by Android adds support for new data types related to fitness, nutrition, and more, and the File integrity manager implement new APIs making use of the fs-verity feature that was added to the Linux 5.4 kernel so that files can be protected by custom cryptographic signatures. Partial screen sharing is a completely new feature in Android 15 that allows users to share or record an app window rather than the […]

Duo 256M is a compact SBC based on SG2002 multi-architecture SoC

Duo 256M is a small board powered by SOPHGO SG2002 multi-architecture Arm/RISC-V/8051 SoC with 256MB of on-chip RAM and a 1 TOPS NPU, a microSD card for storage, a camera connector, a USB-C port for power and programming, and two headers for GPIO expansion. We covered the SOPHGO SG2002 (and SG2000)  Arm+RISC-V+8051 AI SoC earlier this month saying a couple of boards were expected very soon. We’ve already covered Sipeed LicheeRV Nano with optional Ethernet or WiFi 6, and now we’ll look at the Duo 256M designed by Milk-V Technology in more detail since it’s available now. Duo 256M specifications: SoC – SOPHGO SG2002 Main core – 1GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700MHz 64-bit RISC-V C906 core Low-power core – 25 to 300MHz 8051 MCU core NPU – 1 TOPS INT8, supports BF16 Integrated 256MB DDR3 (SiP) Storage MicroSD card slot 32Gbit NAND […]

Ovrdrive USB is an open-source, privacy-oriented USB flash drive that can self-destruct (Crowdfunding)

We have previously covered the Tillitis Tkey, an open-source security key in a USB-C case but the Ovrdrive USB stick is not a security key. It is a simple, plain USB flash drive with a special security feature. It will appear completely blank unless you plug this drive in three times in quick succession. The Ovrdrive flash drive is aimed at journalists in repressive areas and security researchers but may be useful to other security and open-source hardware enthusiasts. As for how it works, the Ovrdrive has two identical circuits connected to the ATtiny24A microcontroller that controls the rapid plug-in functionality. When the flash is plugged in, the microcontroller powers on, and the CHG1 node goes high, charging C3 through D2. The pin will remain high for a while and then slowly discharge via R1 and body resistance. C3 and the identical C14 will remain high through power cycling/a quick […]

Review of Blackview MP80 Processor N97 mini PC with Fedora 39 Linux (Part 2)

After reviewing the Blackview MP80 (Processor N97) mini PC with Windows 11 in detail, we now had time to test it with Fedora 39 Workstation to find out how well it works in Linux. In this second part of the review, we’ll explain our “choice” of Linux distribution, go through benchmarks and features testing, as well as measure fan noise and power consumption, among other test Finding a Linux distribution that works with Blackview MP80 Last year, we reviewed the Blackview MP80 model equipped with an Intel Processor N95 CPU and after the Windows 11 review, we were unable to install Ubuntu 22.04 on the machine with the company eventually telling us Linux was not supported. But several months after the review, a reader commented he could install Fedora 39 on the Blackview MP80 and that it “worked like a charm“. We thought maybe the BIOS had been updated and […]
