Orange Pi AIPro SBC features a 20 TOPS Huawei Ascend AI SoC

Orange Pi AIPro is a new single board computer for AI applications that features a new (and unnamed) Huawei Ascend AI quad-core 64-bit processor delivering up to 20 TOPS (INT8) or 8 TOPS (FP16) of AI inference performance. The SBC comes with up to 16GB LPDDR4X and a 512Mbit SPI flash but also supports other storage options such as a microSD card, an eMMC flash module, and/or an M.2 NVMe or SATA SSD. The board also features two HDMI 2.0 ports, one MIPI DSI connector, and an AV port for video output, two MIPI CSI camera interfaces, Gigabit Ethernet and WiFi 5 connectivity, a few USB ports, and a 40-pin GPIO header for expansion. Orange Pi AIPro specifications: SoC – Huawei Ascend quad-core 64-bit (I’d assume RISC-V) processor delivering up to 20 TOPS (INT8) or 8TOPS (FP16) AI performance and equipped with an unnamed 3D GPU System Memory – 8GB […]

PicoUART6 6x UART to USB bridge supports up to 6 Raspberry Pi 5 boards

PicoUART6 Raspberry Pi 5 UART USB bridge

PicoUART6 is a small USB to UART bridge board that takes a Raspberry Pi Pico board and exposes six UART ports to connect up to six Raspberry Pi 5 SBC’s over the new 3-pin UART connector. The Raspberry Pi 5 has created a lot of buzz since its announcement in September 2023, and people most talked about its higher performance compared to a Raspberry Pi 4 and its new (non-standard) FCP PCIe connector, but the new Raspberry Pi SBC also features a 3-pin JST UART connector that was not used in earlier and frees 3-pin on the 40-pin GPIO header. The PicoUART6 board makes use of this new connector to interface multiple Raspberry Pi 5 over UART and control them through the USB board of the Pico board. PicoUART6 specifications: Footprint for Raspberry Pi Pico board Serial – 6x 3-pin JST UART connectors Expansion – STEMMA QT/Qwiic I2C connector Debugging […]

Review of GEEKOM Mini Air12 Processor N100 mini PC – Part 1: unboxing and teardown

GEEKOM Mini Air12 is a mini PC powered by the popular Intel Processor N100 CPU and coupled with 16GB DDR5 SO-DIMM memory, a 512GB NVMe SSD upgradable up to 1TB. The Windows 11 Pro mini PC also features USB 3.2 Gen 2 USB Type-C ports, HDMI 2.0 video output, gigabit Ethernet, as well as WiFi 6 and Bluetooth 5.2 via an Azureware module. GEEKOM sent us a sample of the Mini Air12 for review. Since we’ve already written about the Mini Air12 specifications, today we will go through an unboxing and look at the hardware design with a teardown, before testing the mini PC in more detail with Windows 11 and Ubuntu 22.04 in the next parts of the review. GEEKOM Mini Air12 Unboxing We received the mini PC is a retail package that protects the device and accessories inside well. The back side of the package lists some basic […]

OpenMV CAM RT1062 camera for machine vision is programmable with MicroPython

Following the success of the OpenMV Cam H7 and the original OpenMV VGA Camera, OpenMV recently launched the OpenMV CAM RT1062 powered by NXP’s RT1060 processor. This new camera module integrates a range of features, including a high-speed USB-C (480Mbps) interface, an accelerometer, and a LiPo connector for portability. Similar to its predecessor, this camera module also features a removable camera system, and it is built around the OV5640 image sensor which is more powerful in terms of resolution and versatility. However, the previous Omnivision OV7725 sensor, used in the OpenMV Cam H7 has a far superior frame rate and low-light performance. OpenMV provides a Generic Python Interface Library for USB and WiFi Comms and an Arduino Interface Library for I2C, SPI, CAN, and UART Comms which can be used to interface your OpenMV Cam to other systems. To program the board, you can use MicroPython 3 with OpenMV IDE, […]

Genmitsu Z5-1 fiber laser engraver review

Good day. Karl here. Today I would like to share my experiences with the Genmitsu Z5-1 fiber laser engraver in this review. What is an infrared Galvo laser? A fiber laser is also known as an infrared Galvo laser. Let’s break this combination of words down. Infrared is first. Up to this point, I have reviewed several powerful blue diode lasers for the site. All of them have had 455nm wavelength lasers. In contrast, the Genmitsu Z5-1 laser we are looking at today has a 1064nm wavelength that is outside of the visible spectrum. With infrared, we can mark different materials. Notable plastics and metals are easy to mark with this laser. Galvo is next and was a term I was not familiar with. “Galvo” is a condensed form of “galvanometer.” It’s an electromechanical device used for precise mirror or optical element control in laser and optical systems. Galvanometers are […]

GEEKOM A5 Review – Part 3: An AMD Ryzen 7 5800H mini PC tested with Ubuntu 22.04

In the first part of GEEKOM A5 mini PC review, we had a look at the hardware with an unboxing and teardown, we then reviewed the AMD Ryzen 7 5800H mini PC with Windows 11 Pro in the second part, and we’ve now had time to test the GEEKOM A5 mini PC with Ubuntu 22.04 to check how well it can work in Linux, and we’ll report our experience in this article. Installing Ubuntu 22.04 on GEEKOM A5 We shrank the Windows 11 partition by half to install Ubuntu 22.04 in dual boot configuration alongside the operating system from Microsoft. Ubuntu 22.04.3 was installed successfully using a USB drive. and everything went relatively smoothly, except WiFi didn’t work reliably (more than that later). So we had to use Ethernet for most of the review, and we used the GL.iNet Spitz AX router (GL-X3000NR) configured in repeater mode using an Ethernet […]

M.2 10GbE network card sells for $86

Almost two years ago, we wrote it was possible to add 10GbE to your system with a M.2 network card based on a Marvell AQC113 chip for about $170. But I’ve now been made aware prices may have come down a lot as another M.2 10GbE network based on the Marvell AQC107 chipset is now selling for $86 including shipping (to Thailand). Just like the previous model, the M.2 card does not include an RJ45 port, instead, it’s included in a separate board that’s mountable to a standard PC plate and connected through a flat cable to the M.2 module. Specifications: Network controller – Marvell AQC107 PCIe Gen3 x4 10Gbps Ethernet controller supporting 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-T (but not 10BASE-T) Aquantias AQrate PHY up to 10GbE using Cat 6a cables, as well as 5 GbE and 2.5 GbE over 100 meters with Cat 5e cables Energy Efficient Ethernet […]
