NanoPi R2S Dual Gigabit Ethernet SBC & Router is Powered by Rockchip RK3328 SoC

FriendlyElec launched NanoPi R1S router with two Ethernet ports based on either Allwinner H3 or H5 processor coupled with 512MB RAM last November. Both ports are “Gigabit” Ethernet port, but one is implemented via a USB 2.0 to Ethernet controller with a maximum bandwidth of around 330 Mbps. If you’d like to get two Gigabit Ethernet reaching close to 1 Gbps each, and your target application would benefit from a bit more memory, the company is now working on NanoPi R2S based on Rockchip RK3328 processor with 1GB DDR4 memory, one Ethernet port using the GMAC from the chip, and one Ethernet port relying one a USB 3.0 to Ethernet controller. The rest of NanoPi R2S specifications are pretty similar to the earlier board except WiFi is also gone: SoC – Rockchip RK3328 quad-core Cortex-A53 @ 1.5 GHz with Arm Mali-450MP2 System Memory – 1GB DDR4 RAM Storage – MicroSD […]

Getting Started with Amlogic NPU on Khadas VIM3/VIM3L

Shenzhen Wesion released the NPU toolkit for Khadas VIM3/VIM3L last November, so I decided to try the latest Ubuntu 18.04 image and the NPU toolkit on Khadas VIM3L, before switching to VIM3 for reasons I’ll explain below. I’ve followed two tutorials from the forum and wiki to run pre-built samples and then building a firmware image and samples from source. Khadas VIM3L and VIM3 Have Different & Optional NPUs This will be obvious to anyone who read the specs for Khadas VIM3 and VIM3L that the former comes with a 5 TOPS NPU, while the one in the latter only delivers up to 1.2 TOPS. But somehow, I forgot about this, and assume both had the same NPU making VIM3L more attractive but this type of task, Obviously I was wrong. But the real reason I stopped using Khadas VIM3L can be seen in the photo below. My board is […]

Beelink BT4 Mini PC Review – Slow, Buggy, Fan-cooled, and Overheating

Intel’s low-cost chip shortage has been so bad that Beelink has had to demothball some Atom chips when creating their new mini PC the Beelink BT4. This is one of the cheapest new mini PCs recently launched and uses the somewhat now old Cherry Trail Intel Atom x5-Z8500 CPU which was launched at the start of 2015 and is a quad-core 4-thread 1.44 GHz processor boosting to 2.24 GHz with Intel’s HD Graphics. The BT4 is the same form factor as the more recent Beelink mini PCs being a half-thick ‘NUC’ style device physically consisting of a 120 x 120 x 22 mm (4.72 x 4.72 x 0.87 inches) plastic rectangular case. This is not a passive device as it contains a small fan that stays on after the device has been shut down. The front panel has only a blue ‘power’ LED and the rear panel includes the power […]

OnLogic Introduces Four Apollo Lake Pico-ITX SBC’s with Integrated Heatsink

We previously covered some Apollo Lake Pico-ITX boards with the likes of GIGABYTE GA-PICO3350 or AAEON PICO-APL3 motherboards, but there are now more options with OnLogic – formerly known as Logic Supply – recently launching four Apollo Lake Pico-ITX SBC’s. OnLogic EPM160, EPM161, EPM162, and EPM163 are powered by either an Intel Celeron N3350 dual-core processor or an Intel Pentium N4200 quad-core SoC with different memory capacities, display and networking options. OnLogic EPM16x specifications: SoC EPM160, EPM161, EPM162 – Intel Celeron N3350 dual-core Apollo Lake processor @ 1.1 GHz / 2.4 GHz (Burst frequency) with Intel HD Graphics 500 EPM163 – Intel Pentium N4200 quad-core Apollo Lake processor @ 1.1 GHz / 2.5 GHz (Burst frequency) with Intel HD Graphics 500 System Memory / Storage EPM160 – 1 GB LPDDR4-2133, MicroSD card slot, mSATA (shared PCIe Mini Card slot) EPM161 – 2 GB LPDDR4-2133, 8GB eMMC flash, MicroSD card slot, […]

Beelink T45 Review with Windows and Linux, and Tweaking BIOS Power Limits

[Update December 23, 2019: We’ve been informed by Beelink that the T45 has been updated to the 6W Celeron N4200 processor instead, and the system is now cooled with a fan. The model reviewed in this post is the fanless version with a 10W Intel J4250 processor, which was never sold] [Update January 30, 2020: We’ve now posted a review of the new model at Beelink Gemini T45 Pentium N4200 Mini PC Review] Beelink have further extended their ‘Gemini’ range of mini PCs by adding the T45. This is a passively cooled mini PC that is effectively a companion to the J45 as it again uses the slightly older Apollo Lake Intel Pentium J4205 CPU which is a quad-core 4-thread 1.50 GHz processor boosting to 2.60 GHz with Intel’s HD Graphics 505. Although the T45 is a ‘NUC’ style mini PC physically consisting of a 119 x 119 x 17.7 […]

UP Xtreme Edge (UPX-Edge) Embedded Computer is Built around UP Xtreme Whiskey Lake SBC

AAEON UP Xtreme SBC was launched last June with a choice of 15W Whiskey Lake processors, namely Intel Celeron 4305UE dual-core processor, Intel Core i3-8145UE dual-core 4-thread processor, Intel Core i5-8365UE / Core i7-8665UE quad-core 8-thread processors. The company has now launched a complete embedded computer built around UP Xtreme SBC named UP Xtreme Edge Computing System, or simply UPX-Edge for short, that’s a slight variation of the fanless chassis offered for the SBC during the Kickstarter campaign. UPX-Edge specifications: SoC (one or the other) Intel Celeron 4305UE dual-core processor @ up to 2.2 GHz with 2MB cache, Intel UHD 610 graphics Intel Core i3-8145UE dual-core 4-thread processor @ up to 2.1 GHz / 3.9 GHz (Turbo) with 4MB cache, Intel UHD 620 graphics Intel Core i5-8365UE quad-core 8-thread processor @ up to 1.6 GHz / 4.1 GHz (Turbo) with 6MB cache, Intel UHD 620 graphics Intel Core i7-8665UE quad-core […]

Ubuntu 18.04 on Beelink Gemini J45 Mini PC (Fix and Review)

When I recently reviewed the Beelink J45 (aka Beelink Gemini J), a mini PC that uses the slightly older Intel Apollo Lake Pentium J4205 processor, whilst Windows 10 Pro ran fine it was unsuitable for Ubuntu because after installation the system became unstable and problems were encountered when running anything that loaded the system. The main issue was that when connected via wired-ethernet performing a command like ‘sudo apt upgrade’ would cause the ethernet to drop after which only a reboot would restore the connection. At the time it, was unclear what the cause was however a solution to the issue was posted by ‘gambetta’ on the Beelink forum. Basically it consists of installing the r8168 module which is the Linux device driver released for RealTek RTL8168B/8111B, RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D, RTL8168DP/8111DP and RTL8168E/8111E Gigabit Ethernet controllers with PCI-Express interface. To paraphrase the ‘README.Debian’ file, you use ‘r8168-dkms because the in-kernel […]

A Look at Ubuntu on MINIX NEO G41V-4 and J50C-4 Mini PCs

MINIX Technology Limited recently released two new Gemini Lake mini PCs running Windows 10 Pro namely the MINIX NEO J50C-4 actively-cooled mini PC with an Intel Pentium Silver J5005 processor and the MINIX NEO G41V-4 fanless mini PC powered by an Intel Celeron N4100 processor. Whilst each mini PC comes with 64GB of eMMC with pre-installed Windows 10 Pro together with 4GB of RAM they also support the addition of an optional 2280 M.2 drive and the MINIX NEO J50C-4 allows optional memory upgrades. Prior to testing their performance under Ubuntu, I established a comparison baseline by updating Windows to version 1903 and then running my standard set of benchmarking tools first with the default configuration of each mini PC and then repeated having installed the official MINIX 2280 M.2 240GB drives for each device together with adding an extra 4GB RAM to the MINIX NEO J50C-4. The results can […]
