NanoPi R5S router review – Part 1: Unboxing, OpenWrt, and iperf3 benchmarking

NanoPi R5S router review

FriendlyElec has just launched the NanoPi R5S mini router powered by a Rockchip RK3568 processor, and the company kindly sent me two samples for review. In the first part of the review, I’ll check out the device itself, the internal design, the preinstalled OpenWrt, and run some networking benchmarks with iperf3. NanoPi R5S unboxing   The router comes fully assembled together with a 3M sheet with 6 rubber feet, which, as we’ll see below, are not really necessary. A microSD card socket can be found on one of the sides, while the rear panel comes with a USB-C port for power, a WiFi antenna hole (which can also be used to run cables for GPIO. UART console, etc…), two 2.5GbE RJ45 LAN ports, a Gigabit Ethernet WAN port, and HDMI video output. We’ll find a Mask button for firmware flashing on the other side, and the front panel features four […]

Khadas VIM4 SBC review – Part 3: Ubuntu 22.04

Khadas VIM4 Ubuntu 22.04

Here’s the last part of Khadas VIM4 review with Ubuntu 22.04 “Jammy Jellyfish”. You may want to check out our previous parts with the unboxing and first boot, followed by Android 11 if you haven’t already done so. Ubuntu 22.04 installation on Khadas VIM4 I used the same method of installation with OOWOW firmware that can download the image directly from Khadas server, and install it to the eMMC flash. Since I already had Android 11 running on the board, I had to keep pressing the function key (middle), then shortly press the reset button,  before releasing the function key and entering OOWOW interface. From there, I selected Ubuntu 22.04 Gnome, and went ahead with the download. The download was fast with the 758.2MB compressed image downloaded in a couple of minutes, then I simply selected “Install” to go further, and replace Android 11… .. and after rebooting the board […]

Beelink SEi8/SER3 review – Intel Core i3-8109U and AMD Ryzen 3 3200U mini PCs face off in Windows 11 (part 1)

Beelink sei8 ser3 review

In the past, new mini PCs were released as a result of new processors coming to market. However, with the pandemic and its consequences on the supply chain, some Chinese manufacturers’ survival response has been to source old processors in order to continue presenting new devices. It could be argued that for this approach to be successful these alternative older processors should at least be comparable in performance terms to the latest processors that are currently, or theoretically potentially, now available. In terms of low-end Intel mini PC processor chronology which started with Bay Trail and then Cherry Trail followed by the Lakes of Apollo and Gemini, the current benchmark is Jasper Lake. A good example of this adaptation to market circumstances is Beelink’s release of their latest additions to their SEi and SER product lines which feature the older Intel Core i3-8109U (Coffee Lake) and AMD 3200U processors respectively.

Trying out Edge Impulse machine learning platform on XIAO BLE Sense board

double-sided sticky tape boards

I had seen the Edge Impulse development platform for machine learning on edge devices being used by several boards, but I hadn’t had an opportunity to try it out so far. So when Seeed Studio asked me whether I’d be interested to test the nRF52840-powered XIAO BLE Sense board, I thought it might be a good idea to review it with Edge Impulse as I had seen a motion/gesture recognition demo on the board. It was quite a challenge as it took me four months to complete the review from the time Seeed Studio first contacted me, mostly due to poor communications from DHL causing the first boards to go to customs’ heaven, then wasting time with some of the worse instructions I had seen in a long time (now fixed), and other reviews getting in the way. But I finally managed to get it working (sort of), so let’s […]

Khadas VIM4 Review – Part 2: Android 11 preview and benchmarks

Khadas VIM4 Android 11 Review

In the first part of Khadas VIM4 review, I showed off the Amlogic A311D2 SBC and some accessories such as the DIY case and M2X expansion board to add M.2 SSD and modem and tried out OOWOW cloud services to install Ubuntu 20.04 server. I’ve now just gotten Fiber Internet at home, so it’s much more practical to test the system, and in the second part of the review, I’ve installed Android 11 on the VIM4 board, checked out settings and system info, and ran some benchmarks.  It will be more like a preview since Android 11 is not a consumer-friendly system at this time, and is more designed for people wanting to build their own applications. Installing Android 11 on Khadas VIM4 with OOWOW system Last time around, I used OOWOW system install in the SPI flash on the board to download and install Ubuntu 20.04 server to the […]

Ultenic T10 review – A self-emptying 2-in-1 smart vacuum robot with mopping function

Ultenic T10 smart vacuum cleaner review

Ultenic T10 is a 2-in-1 smart vacuum cleaner and mopping system with a self-emptying base that’s quite similar to the Cybovac S31 robot I reviewed a little over a year ago. The Cybovac vacuum cleaner still works fine, but it has some shortcomings, so when Ultenic asked me whether I would be interested in reviewing their T10 unit, I accepted, and here I am with a new smart robot vacuum cleaner that I’ll review with the Android app in a larger house. Ultenic T10 unboxing The package and hardware are very similar to what I got with the Cybovac model. The robot comes with a charging base that’s pretty large since it includes its own dust bag for the self-emptying function. Key features listed for the T10 vacuum cleaner: Navigation Type – LDS laser for visual SLAM function Suction power Carpet pressurization – 2700 Pa Fixed-point cleaning – 2700 Pa […]

Khadas VIM4 heatsink

Khadas VIM4 is a compact Amlogic A311D2 octa-core Cortex-A73/A53 SBC with 8GB RAM, HDMI input and output, WiFI 6 connectivity, and more. You can check our earlier post for the full specifications. The good news is that it will officially launch on May 10. I’ve also just received a Khadas VIM4 review sample today together with accessories. Today, I’ll start by checking out the board, assembling the kit, and trying out OOWOW services to boot OS from the cloud, before testing available operating systems in more detail in the second part of Khadas VIM4 review a little later. Khadas VIM4 kit unboxing I received everything in a blank cardboard package with several small packages inside. Besides Khadas VIM4 SBC, we’ve got a plastic + metal enclosure with screws and screwdriver, two antennas for WiFi and Bluetooth, a USB Type-C power supply, a USB-C cable, an M.2 expansion board, a short […]

MOREFINE S500+ review

Morefine has recently released their S500+ series of mini PC series which features models with either a Zen 2 or Zen 3 AMD mobile processor. Morefine kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu. Morefine S500+ Hardware Overview The S500+ physically consists of a 149 x 145 x 40mm (5.87 x 5.71 x 1.57 inches) square metal case with a plastic top. As an actively cooled mini PC, it is available with either an AMD Zen 2 or Zen 3 mobile processor.
