Axiomtek GMB850 Raptor Lake Refresh mini-ITX motherboard GMB850 is made for casino gaming machines

Intel Raptor Lake mini-ITX motherboard casino gaming

Axiomtek GMB850 is a mini-ITX motherboard powered by up to 14th Gen Intel Raptor Lake-Refresh processors and designed for casino gaming machines requiring advanced features like gaming analytics, real-time player interaction systems, and dynamic content management. While mini-ITX motherboards may serve multiple markets, there’s a specific market for casino and arcade gaming often using AMD processors. We’ve previously covered such boards in the past with the AMD Ryzen Embedded V2000-powered Sapphire FS-FP6 or the AMD Ryzen Embedded V1000/R1000-based Axiomtek GMB140. Axiomtek Gaming’s GMB850 is a more powerful update with Intel Raptor Lake Refresh processors supporting up to four independent displays with up to 4K resolution and gaming I/O modules making it suitable for casino slot machines, electronic table games, and video walls.

JetKVM – A $69 KVM over IP solution with open-source software

We’ve been writing about some low-cost KVM over IP solutions like the Sipeed NanoKVM Cube or GL.iNet Comet in recent times, but the JetKVM has been pointed out to me as another alternative with the benefit of having open-source software (which the NanoKVM also got last month). The JetKVM was launched for $69 on Kickstarter last fall and the crowdfunding campaign was amazingly successful with over 4 million dollars raised from just over 30,000 backers. Key features include 1080p60 video with 30-60ms latency using H.264 encoding, mouse and keyboard emulation, remote management via JetKVM Cloud using WebRTC for accessing the devices from outside the LAN, and open-source software written in Golang on Linux. JetKVM specifications: SoC – Rockchip RV1106G3 CPU – Arm Cortex A7 @ 1.0GHz VPU – H264 & H265 hardware encoder Memory – 256 MB DDR3L on-chip Storage – 16 GB eMMC flash Display – 1.69-inch IPS capacitive […]

Mini UPS with 5V, 9V, 12V DC, and PoE output could be useful for routers, security cameras, SBCs, and mini PCs

Mini Uninterruptible Power Supply DC USB PoE

Most uninterruptible power supplies (UPS) require AC voltage and use specific batteries that must be changed every few years. But those may be oversized and not the most efficient if you just want to keep single board computers (SBCs), low-power mini PCs, routers, or security cameras up and running during power failures. Luckily, some mini UPS solutions use standard rechargeable 18650 batteries, output 5V, 9V, or 12V DC, or even PoE (15V/24V) which may be more suitable for those use cases. Many mini UPS solutions come from WGP (Wonderful Green Power), so let’s have a look at the WPG103A model. WPG103A mini UPS specifications: Batteries – 4x 18650 batteries for a combined 10,400 mAh capacity Protection – Overcharge, over-discharge, overcurrent, and short circuit protection Misc – Power button, status LEDs Power Input – 12V/2A via DC jack Power Output 5V via USB Type-A port (likely limited to 1.5A or 2A […]

Forlinx FET3506J-S low power system-on-module features Rockchip RK3506J industrial-grade tri-core Cortex-A7 SoC

Forlinx FET3506J-S system-on-module (SoM) is based on a Rockchip RK3506J SoC, the industrial version of the RK3506 tri-core Cortex-A7 SoC, designed for smart industrial applications, and operating at a low power consumption of about 0.7 Watts. The Rockchip RK3506 SoC was first unveiled in 2023 through a product roadmap. However, we only spotted it in a product at the very end of 2024 with the Luckfox Lyra and Luckfox Lyra Plus featuring a MIPI CSI display connector and optional Ethernet. The Forlinkx FET3506J-S CPU module is the first platform with the industrial version (RK3506J), and the company also provides the OK3506 carrier board/development board for evaluation. Forlinx FET3506J-S system-on-module Specifications: SoC – Rockchip RK3506J CPU 3x Arm Cortex-A7 core up to 1.5 GHz or 1.6 GHz (depending on where one looks in the documentation) Arm Cortex-M0 real-time core GPU – 2D GPU only No VPU, no NPU System Memory – […]

Canonical now officially supports Ubuntu on NVIDIA Jetson system-on-modules

The NVIDIA JetPack SDK has been based on Ubuntu ever since it was created (although the Jetpack 6 SDK changed that somewhat), so I was surprised to read that Canonical now officially supports Ubuntu on NVIDIA Jetson, since I assumed there may have already been a partnership in place. The announcement explains that Canonical has announced the General Availability (GA) of Ubuntu for the NVIDIA Jetson Orin for edge AI and robotics “bringing enterprise-grade stability and support” to the popular system-on-modules. Canonical further explains the collaboration enables better performance with optimized Ubuntu images for the NVIDIA Jetson platform, enterprise-level security with updates and long-term support, a unified environment from edge to cloud, and improved stability and reliability with Canonical’s QA team performing over 500 OS compatibility-focused hardware tests. If we visit the NVIDIA Jetson page of the Ubuntu website, we’ll find Ubuntu Server 22.04 images for the Jetson AGX Orin, […]
