Khadas VIM4 single board computer was first unveiled last October with Amlogic A311D2 octa-core Cortex-A73/A53 processor, 8GB LPDDR4X, but it’s only been launched today, and you can now buy the Khadas VIM4 board for right under $200. It is an upgrade to Khadas VIM3 Pro launched with Amlogiv A311D hexa-core processor a few years ago, and our testing in Android 11 revealed the main benefit may be the upgrade GPU that delivered a 67% boost in 3DMark, but CPU multi-core performance and memory bandwidth will also see some benefits over Amlogic A311D, even against in overclocked systems like ODROID N2+. Here’s a reminder of Khadas VIM4 specifications: SoC – Amlogic A311D2 octa-core processor with 4x Arm Cortex-A73 cores @ up to 2.2 GHz and 4x Cortex A53 cores @ up to 2.0 GHz, Arm Mali-G52 MP(8EE) GPU, (Note: no NPU at this time) System Memory – 8GB LPDDR4X @ 2016 […]
Khadas VIM4 Review – Part 2: Android 11 preview and benchmarks
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 […]
DIY SBC cases and SBC Case Builder tool based on OpenSCAD
Since you can’t always rely on single board computer (SBC) vendors to provide a case to match your needs, some went the DIY route. Willy Tarreau designed some laser-cut enclosures with Inkscape for various SBCs, while hominoids went a step further by developing the “SBC Case Builder” tool to automatically generate various types of 3D printable enclosures using OpenSCAD. Willy designed five similar enclosures for Khadas VIM3/VIM3L, FriendlyELEC NanoPi Fire3, SolidRun Clearfog Base networking SBC, Libre Computer AML-S805X-AC (aka “La Frite”), and AAEON UP Board. All cases are available in Inkscape SVG format, and Willy accepts contributions for other boards. You’ll need a laser engraver or CNC router to cut out those enclosures. Hominoids’ SBC Case Builder project attempt to automatize enclosure generation for SBCs using SBC Model Framework written in OpenSCAD. Work has focused on ODROID boards so far, but it should work for other vendors too. The parameters […]
Khadas VIM4 Review – Part 1: Unboxing, kit assembly, and first boot with OOWOW
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 […]
