NanoPi M4B Rockchip RK3399 SBC Drops the USB 3.0 Hub, Adds Bluetooth 5.0, an ADB Switch

NanoPi M4B

NanoPi M4 was launched last year (2018) as a Rockchip RK3399 SBC following Raspberry Pi 3B+ form factor with 2 or 4GB DDR3 RAM, and was followed by NanoPi M4V2 this September with 4GB LPDDR4 memory, and power & recovery buttons. FriendlyELEC has been working on yet another revision with NanoPi M4B mixing some of the features of M4 and M4V2 such as DDR3 memory and power & recovery buttons, but the biggest change is the removal of the USB 3.0 hub which allowed for four USB 3.0 port, and now the company is going native leveraging the two USB 2.0 interfaces and two USB 3.0 interfaces inside Rockchip RK3399 processor which should lower the BoM cost, and in some cases improve performance. NanoPi M4B specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0GHz, 4x Cortex-A53 @ up to 1.5GHz, a Mali-T864 GPU […]

AOPEN Chromebox Mini is Designed for Digital Signage and Kiosks

ChromeOS Digital Signage

Most ChromeOS devices are designed for either the consumer or educational markets, but Google’s operating system can also be used for commercial applications such as digital signage. A cheap way to set up a ChromeOS based digital is to get a ChromeBit (around $100 used) and install one of the Digital Signage apps for the OS. But as I checked out Linux 5.4 changelog, I came across AOPEN Chromebox Mini (codename Fievel) powered by a Rockchip RK3288 processor and described as an “enterprise-ready” Chromebox for 24/7 operation as digital signage or kiosk. AOPEN Chromebox Mini specifications: SoC – Rockchip RK3288C quad-core Cortex-A17 processor @ up to 1.8GHz with Arm Mali-T764MP GPU clocked at up to 600 MHz System Memory – Dual-channel 4GB LPDDR3 Storage – 16GB eMMC 5.0 flash Video Output – HDMI up to 1080p60 Audio – 1x combo jack with Line out/Line in Connectivity – Gigabit Ethernet, WiFi […]

Pocket Popcorn Computer Handheld Linux Computer Looks Like an Improved, Faster PocketCHIP (Crowdfunding)

Pocket Popcorn Computer

PocketCHIP was a Linux handheld computer powered by Allwinner R8/GR8 Cortex-A8 based CHIP board. The battery-powered device came with a small resistive display, 512 MB RAM, 4GB NAND flash, and a keyboard allowing to run Debian with PICO8 GUI so you could play retro games, access the terminal and so on. But since Next Thing Co folded last year the products are not available anymore. Since the designs were open source, Source Parts first tried to resurrect the board via their slightly modified Popcorn Computer but the Kickstarter campaign was unsuccessful. The company is now attempting to bring back PocketCHIP (sort of) with Pocket Popcorn Computer (abbreviated as Pocket P.C.) with a new design, and a much more powerful quad-core Cortex-A53 processor and overall better specs. Pocket Popcorn Computer specifications: SoC – Allwinner A64 quad-core Arm Cortex-A53 CPU with Arm Mali-400MP2 GPU System Memory – 2GB DDR3 RAM Storage – […]

Lenovo Enters the SBC Market with Leez LP710 RK3399 Board

Lenovo Leez P710 SBC

It’s always interesting to look into mainline Linux changelog either to find out about new software features, but also new hardware platform. And earlier today, I wrote about Linux 5.4 release, I noticed comments about “Leez RK3399 P710 SBC“. After searching a bit, it turns out it’s a single board computer by Lenovo, which the company apparently showcased at World Mobile Congress in Spain last February. Leez is apparently a team part of Lenovo. Lenovo Leez P710 board specifications: SoC – Rockchip RK3399 hexa-core processor with 2x Cortex-A72 cores @ up to 2.0 GHz, 4x Cortex-A53 cores, and an Arm Mali-T860MP4 GPU System Memory – 2 or 4GB LPDDR4 Storage – 16GB eMMC flash, MicroSD card slot Video Output – HDMI 2.0a up to 4K @ 60 Hz, 4-lane MIPI DSI, DisplayPort via USB-C port Audio – Audio jack + digital audio output via HDMI Camera I/F -2x 4-Lane MIPI-CSI […]

Linux 5.4 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.4 Changelog

Linus Torvalds has just announced the release of Linux 5.4: Not a lot happened this last week, which is just how I like it. And as expected, most of the pull requests I got were for the 5.5 merge window, which I’ll obviously start working through tomorrow. What little there is here is mostly some networking updates (mix of network drivers and core networking), and some minor GPU driver updates. Other than that it’s a small collection of random other things all over. The appended shortlog is small enough that you might as well just scroll through it. Anyway, this obviously opens the merge window for 5.5. It’s not ideal timing with Thanksgiving week coming up, but it hopefully shouldn’t be too much of an issue. If I fall behind (not because I’m all that big of a fan of the indiscriminate and relentless turkey-killing holiday) it’s because we’ve got […]

Galerdo AI Swimming Tracker Gives Audio Feedback, Plays Music – No Ear Buds Needed (Crowdfunding)

Galerdo Beker Pro Galerdo is a simple to use, swimmers attendant, that holds tight to the head and collects data.  It offers interactive audio, AI advice underwater and even plays music through bone-conduction.  We previously reported on fitness and swimming tracker Makibes F69 IP68 Smartwatch but it lacked audio support. Feature Awards for Galerdo Galerdo won the CES 2020 Innovation Award for Swim Tracker, AI Voice Assistant and Handset Free features. Previous and Present Devices Galerdo Inc has a previous bone-conduction audio device that offered music underwater to swimmers, without the need for a headband or earbuds.  The latest device simply called Galerdo adds AI data collection and spoken advice as the user is swimming, in real-time. Quick Run Down on Bone-Conduction The AI technology that is used in the Galerdo is further enhanced by the bone-conduction transfer of sound and is a technology industry that is growing rapidly. It […]

MINIX NEO G41V-4 Mini PC Review – Part 2: Windows 10 Pro

MINIX NEO G41V-4 HDMI + VGA

MINIX NEO G41V-4 is the latest mini PC from the Hong Kong-based company, and this time they’ve gone fanless with a new design that should allow proper cooling with a large heatsink, plenty of ventilation holes on the top, as well as a dust-resistant meshing to present dust from entering inside the enclosure. I’ve now had time to review the fanless mini PC, and I’ll report my experience with Windows 10 Pro, while Ian did his part with Ubuntu 18.04. Switching to Windows 10 Boot from SSD I had installed the optional 240GB SSD in the first part of the review. It offers an easy way to get more storage and performance, and you don’t need to reinstall Windows 10 Pro since it’s already installed in the SSD. You just need to change some settings in the BIOS as explained in the user manual. To be on the safe side, […]

Getting Started with Embedded Linux on RISC-V in QEMU

RISC-V Linux QEMU Buildroot

RISC-V is getting more and more popular, but if you want to run Linux on actual hardware it’s currently fairly expensive since you either need to rely on HiFive Unleashed SBC ($999), or expensive FPGAs. Another solution is running Linux RISC-V via QEMU emulator,  and I showed how to do this using BBL (Berkeley Boot Loader),  Linux 4.14, and busybear rootfs. If you check the comments section of that earlier post you could also try out Fedora RISC-V images in QEMU. Bootlin has now published a presentation showing how to run embedded Linux on RISC-V in QEMU with many of the same components as in the previous instructions, but with a more up-to-date Linux kernel (5.4), and using Buildroot to build everything from scratch including the toolchain, BBL, the Linux kernel, and a Busybox based root file system. They explain each step in detail in the 45-page presentation to allow […]
