Khadas Edge2 ultra thin SBC is powered by Rockchip RK3588S processor

As noted in the Khadas VIM1S announcement, the company is also preparing to launch the Khadas Edge2 single board computer with a Rockchip RK3588S octa-core Cortex-A76/A55 processor and a thickness of just 5.7mm (before a low-profile heatsink is installed). The new board follows a similar form factor as the original Khadas Edge board powered by a Rockchip RK3399 processor, except the edge connector is gone, so it can’t be used as a system-on-module anymore, but remains the thinnest and one of the most powerful Arm SBCs so far. Khadas Edge2 Basic/Pro specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with four Cortex-A76 cores @ 2.25 GHz, four Cortex-A55 cores @ 1.8 GHz GPU – Arm Mali G610MC4 GPU AI accelerator – 6TOPS NPU VPU 8Kp60 10-bit H.265 decoder, 4Kp60 AV1 video decoder 8Kp30 H.264/H.265 video encoder MCU – STMicro STM32G031K6 Arm Cortex-M0+ microcontroller @ 64 Mhz for power management […]

Khadas VIM1S low-profile SBC features Amlogic S905Y4 quad-core Cortex-A35 SoC

Khadas VIM1S is an upcoming low-profile single board computer powered by an Amlogic S905Y4 quad-core Cortex-A35 processor that’s meant to provide an upgrade to the Amlogic S905X-powered Khadas VIM SBC introduced in 2016, and since then renamed to Khadas VIM1. Khadas has been teasing two new SBCs: the low-end Khadas VIM1S with S905Y4 SoC, and the most powerful Khadas Edge2 board equipped with a Rockchip RK3588S octa-core Cortex-A76/A55 processor. I have received both as you can clearly see from the photo above :), but I’m only allowed to write about information available publicly at this time, so today I’ll introduce the Khadas VIM1S which looks just like the VIM1 board. Khadas VIM1S specifications with highlights in bold showing the differences against the VIM1 Pro model: SoC – Amlogic S905Y4 quad-core Arm Cortex-A35 @ up to 2.0 GHz (real frequency) with Arm Mali-G31 MP2 GPU @ up to 850 MHz MCU – […]

Android 13 is already working on Qualcomm Robotics RB3 and RB5 platforms

Qualcomm Robotics RB3 (aka DragonBoard 845c) and Robotics RB5 boards can already support Android 13, just a few days after the source code was pushed to AOSP (Android Open Source Project). Once upon a time (i.e. a few years ago), it would have taken weeks, and more likely months, to port the latest version of Android (AOSP) to a specific single board computer. But thanks to initiatives such as Project Treble, Android reference boards such as DragonBoard 845c (RB3), HiKey 960, Khadas VIM3, and Qualcomm Robotics Board RB5 can now get the latest version of Android up and running in a matter of days. Android 13 was released on August 15, and Linaro wrote about RB3 and RB5 support on August 18, and while Linaro engineers collaborated with Google engineers before the AOSP, it is still an impressive feat. Amit Pundir, Linaro Engineer, explains how this was made possible: Over […]

Robot cat girl doll leverages Khadas VIM3 SBC for AI-accelerated object detection/tracking

While Khadas VIM4 board has just been launched, the earlier Khadas VIM3 SBC has the advantage of featuring a 5 TOPS NPU that’s being leveraged by Lilium Robotics for their humanoid robots, notably the Lily Delta V7 robot cat girl doll using the Amlogic A311D board to control motors and provide AI features such as face and object detection and tracking. The Delta V7 is offered as an Android kit running Linux (Android refers to humanoid robot here) with a full motorized body kit, a head with a dual camera and sound system, accessories like a dress, wig, cat ears and tail, and other features that are more geared towards the adult crowd… Content of the Lily Delta V7 full Android kit: Full motorized body kit Motorized arms, legs, and torso with wide movement range Arms can support 0.5 kg payload 100 cm high, weighs about 5 kilograms Inserts: Face, […]

Khadas VIM4 SBC review – Part 3: 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 […]

You can now buy Khadas VIM4 SBC for $199.90

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 […]
