Khadas Mind 2 AI Maker Kit – An Intel Core Ultra 7 258V “Lunar Lake” mini PC for developers

Khadas recently announced the Mind 2 mini PC with an Intel Core 5 or 7 “Meteor Lake” mini PC. But the company is prepping the launch of another similar device called the “Khadas Mind 2 AI Maker Kit Dev Workstation” or “Intel Core Ultra Processor (Series 2) AI PC Dev Kit” with a 15th Gen Intel Core Ultra 7 258V “Lunar Lake” processor offering up to 115 TOPS of AI performance. I’ll just call it “Khadas Mind 2 AI Maker Kit” for shorts. The system ships with 32GB RAM and a 1TB SSD, and Khadas says the new system is designed specifically for developers working on AI PC applications, but apart from the faster SoC, it comes with similar features as the Mind 2. This includes HDMI 2.0 video output, two 40Gbps USB4 ports, Wi-Fi 6E (802.11ax), and Bluetooth 5.3 connectivity, as well as two USB 3.2 Gen2 Type-A ports […]

Arduino Core for Zephyr beta released – Let’s give it a try!

Last July, Arduino announced plans to switch from the soon-to-be deprecated Arm Mbed to Zephyr RTOS, and the company has now outed the first beta release of “Arduino Core for Zephyr OS” for a range of boards. From the user’s perspective, this should not change anything. However, there are massive changes under the hood and Arduino sketches are built and executed differently with the Arduino Core for Zephyr. Some highlights of the new Zephyr-based Arduino core implementation include: Dynamic sketch loading – Sketches are compiled as ELF files and dynamically loaded by a precompiled Zephyr-based firmware. Zephyr subsystems support threading, inter-process communication, and real-time scheduling. Fast compiling and smaller binaries since a thin layer of user code and libraries are compiled, while the rest of the ZephyrOS is already binary. You can get started straightaway with the code and instructions on GitHub. You’ll need Arduino 2.x.x for this to work. […]

Raspberry Pi 500 review with Raspberry Pi Monitor and teardown

Raspberry Pi 500 review with Monitor Speaker

The Raspberry Pi 500 keyboard PC is just out along with the 15.6-inch Raspberry Pi Monitor and received samples from Raspberry Pi for review a few days ago. I’ve had time to play with both, so in this review, I’ll go through an unboxing of the kit I received and report my experience with both the keyboard PC and monitor. Unboxing I received two packages. The first one with the Raspberry Pi Monitor, and the second with a Raspberry Pi 500 (UK layout), a 27W USB-C power adapter, and a micro HDMI to HDMI cable. So not quite a full Raspberry Pi 500 Desktop Kit since there’s no mouse and beginner’s manual but close to it. Let’s start with the keyboard PC. The bottom side of the package has some specs and a logo for the keyboard layout, in this case “UK”. There’s only the keyboard PC in the package. […]

GEEKOM GT1 Mega review with Ubuntu 24.10 – Part 3: Linux on an Intel Core Ultra 9 185H “Meteor Lake” mini PC

GEEKOM GT1 Mega Ubuntu 24.10 Linux review

We’ve already had a look at GEEKOM GT1 Mega’s hardware with an unboxing and a teardown before following up with a thorough review of the Intel Core 9 Ultra 185H mini PC with Windows 11 Pro. After being interrupted by some Raspberry Pi reviews, I finally had the time to test the GEEKOM GT1 Mega with Ubuntu 24.10 to check out how well (or not) it works with a recent Linux distribution. I’ve tested the features of the Meteor Lake mini PC in Linux, ran some benchmarks, evaluated storage and network performance, played 4K and 8K videos on YouTube at various frame rates, went through a stress test to check its thermal design, and finally measured the mini PC’s fan noise and power consumption. Ubuntu 24.10 installation I would usually review mini PCs with the latest Ubuntu LTS version which would currently be Ubuntu 24.04.1. However, since the Intel Core […]

SONOFF CAM Slim Gen2 Review – A tiny indoor security camera tested with eWeLink and Home Assistant

We have received the latest tiny indoor security camera from SONOFF: the second generation of the CAM Slim series known as the CAM Slim Gen2 (or CAM S2 for shorts). Some of you might remember the first-generation CAM Slim model reviewed by Jean-Luc about two years ago. The Gen2 version keeps the same 1080p resolution but comes with several upgraded features, including AI algorithms to distinguish living beings, customizable detection zones, customizable privacy zones, sleep mode, enhanced low-light image quality, and flexible storage management. Although it’s packed with several enhancements, its price is lower than the Gen1. Let’s delve into the details! SONOFF CAM Slim Gen2 unboxing Inside the box, you’ll find a compact manual, a USB-C cable, a mounting kit, and a sticker template acting as a drilling guide. The camera is smaller than your palm and comes mounted on a versatile, rotatable base, making installation in various positions […]

Renesas RZ/T2H Cortex-A55/R52 industrial MPU and Dev Board support EtherCAT, PROFINET, and TSN

Renesas RZ/T2H industrial MPU is the most powerful member of its RZ/T2 series of real-time microprocessors. The MPU features four Arm Cortex-A55 CPUs for application tasks and two Cortex-R52 CPUs for real-time control. It supports 9-axis motor control with 3-phase PWM timers, delta-sigma interfaces, and encoder interfaces. It also supports Industrial Ethernet protocols like EtherCAT, PROFINET, and TSN. These features make it ideal for industrial applications such as industrial robots, PLCs, motion controllers, and CNC machines. Renesas launched the RZ/T2L single-core Arm Cortex-R52 MPU just last year, and before that, in 2022, they launched the RZ/T2M dual Arm Cortex-R52 MPU. The RZ/T2L was just a cost-down version of RZ/T2M with an EtherCAT controller, compared to those old controllers the latest RZ/T2H supports 9-axis motor control and compatibility with various industrial Ethernet protocols. Renesas RZ/T2H specifications: CPU 4x Arm Cortex-A55 (64-bit) clocked at up to 1.2GHz with 32KB L1 I/D cache, 1MB L3 cache 2x […]

Giveaway Week 2024 winners announced!

We’re now ready to announce the winners of CNX Software’s Giveaway Week 2024. We offered some of the review samples we tested (and some we did not test) in the last year, and for the fourth year running, RAKwireless also gave away two IoT development kits shipped directly to winners. This year’s prizes also included a RISC-V motherboard, a 3D depth camera, a few Arm development boards, two touchscreen displays, and an Alder Lake-N mini PC/router. All those products can be seen in the photo, minus some accessories. You’ll find more than seven devices because we organized the third Giveaway Week on CNX Software Thailand simultaneously with four prizes. We had seven winners on CNX Software: Jupiter RISC-V mini-ITX motherboard – François-Denis, Canada Orbbec Femto mega 3D depth and 4K RGB camera – Reifu, Japan RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit – OldCrow, Portugal Mixtile Core 3588E development kit […]

Renesas RA8E1 and RA8E2 entry-level Arm Cortex-M85 MCUs target cost-sensitive applications

Fast Prototyping Board for Renesas RA8E1

Renesas has expanded its Arm Cortex-M85-based RA8 series to include two new entry-level MCUs, RA8E1 and RA8E2. The new microcontrollers perform similarly to other Arm Cortex-M85-based microcontrollers and are offered at a lower price point thanks to a streamlined feature set to reduce costs. The RA8E1 and RA8E2 groups of microcontrollers will be useful for high-volume applications in industrial and home automation, healthcare, office equipment, and consumer products. We have previously covered other models in Renesas’ RA8 series, including the Renesas RA8T1, RA8D1, and the very first Cortex-M85 microcontroller, the Renesas RA8M1. The RA8 series consists of microcontrollers based on the Arm Cortex-M85 core with a performance of 6.39 CoreMark/MHz and Arm’s M-Profile Vector Extension which provides a 4x performance boost for DSP and ML workloads while maintaining low power consumption. The RA8E1 and RA8E2 Cortex-M85 microcontroller groups differ mostly in clock speed, available internal and external memory, communication interfaces, […]
