Khadas VIM2 v1.4 SBC Gets Bluetooth 5, Thermal Improvements, a Larger SPI Flash

Khadas VIM2 Thermal Design

Announced in summer of 2017, Khadas VIM2 was the first Amlogic S912 development board, and I had the chance to review the board with a dual DTV tuner add-on board shortly after launch, eventually explaining how to use VIM2 as a live TV streaming server in Android. Shenzhen Wesion has however recently launched Khadas VIM2 v1.4 with various improvements they neatly describe in a PDF document. Before I go through the main changes, I’d like to remind readers there are three versions of Khadas VIM2 (v1.2) boards: VIM2 Basic – 2GB DDR4, 16GB eMMC flash, Ampak AP6356S wireless module with 802.11 b/g/n/ac WiFi 5, and Bluetooth 4.1 connectivity VIM2 Pro – 3GB DDR4, 32GB eMMC flash, Ampak AP6359SA wireless module with 802.11 b/g/n/ac with RSDB and Bluetooth 4.2 connectivity VIM2 Max – 3GB DDR4, 64GB eMMC flash, Ampak AP6359SA wireless module with 802.11 b/g/n/ac with RSDB and Bluetooth 4.2 connectivity One of the first change in VIM2 v1.4 is the …

Khadas Edge Review – Part 3: Android 7.0 Preview

Khadas Edge Android 7.0

Hey Karl here with a look at a preview of Android on the Khadas edge. Jean-luc has done 2 parts already. The first one looking at the hardware side, and a second looking at Ubuntu. A third img is available that for LibreELEC. The initial release was very barebones, and the 2nd version is much more polished with the Play Store installed now and overall feels snappier. Khadas is supposed to be sending an Edge over to Super Celeron, and I hope they follow through. DHL DHL really messed up my board. Here are some pics. I will only be testing with Ethernet because the WiFi antenna got damaged badly and even bent the heatsink. I think the board is slightly damaged as well. I can only flash using the buttons on the board and not the carrier board. Everything else seems OK. Due to the damage I am using a heatsink that I had. I took some temp readings …

Khadas Edge Developer Package Review – Part 1: Unboxing, Captain and Edge-IO Expansion Boards

Khadas Edge Captain Board

Shenzhen Wesion recently launched an Indiegogo campaign for their Rockchip RK3399/RK3399Pro based Khadas Edge, Edge-1S and Captain boards. The Edge boards have an interesting form factor as they are both standalone boards, and system-on-modules compatible with Captain carrier board, and the smaller Edge-IO board. While the crowdfunding campaign is on-going, the company decided to send me an early version of Khadas Edge Developer Package for evaluation. I’ll start out by checking out the content of the kit, and show how to get started with assembly, before reviewing the board with Linux at a later date. Khadas Edge Developer Package Unboxing I received the developer kit in a blank carton board package, but they’ll likely have a prettier package at launch like they did for heir VIM2 board. Anyway, the important part is the content. From top left to bottom right: An IR remote control, the package for the Edge board + Captain, a USB-PD power supply, Edge-IO board with spacers, …

Rockchip RK3399Pro EVB and NPU Performance Demos (Video)

Rockchip RK3399Pro EVB

Rockchip RK3399Pro was announced as an updated version of RK3399 processor with an NPU (Neural Processing Unit) capable of delivering 2.4 TOPS for faster A.I. workloads such as face or object recognition. There haf been some delays in the past because of a redesign of the processor that placed the NPU’s RAM on the PCB instead of on-chip for cost reasons. Eventually we got more details about RK3399Pro, and today I also received a 15-page presentation with some more information about the software, and processor itself. But even more interesting, that’s the first time I see Rockchip’s official RK3399Pro EVB (Evaluation Board), and the guys at Khadas uploaded a video to explain a bit more about the board, and showcase the NPU performance measured up to 3.0 TOPS with an object recognition demo, and an “body feature” detection demo – for the lack of a better word – running in Android 8.0. Eventually, Shenzhen Wesion (Khadas) will launch their own …

Khadas Edge RK3399/RK3399Pro Board Crowdfunding Campaign Launched

Khadas Edge is another upcoming Rockchip RK3399 board that we initially covered this summer, and comes with a particular design in the sense it is both a single board computer with USB and Ethernet port, and a system-on-module through its edge connector. Later on we found out, the company was working on a variant called Khadas Edge-V with the edge connector being replaced by a more standard 40-pin header, as well as Khadas Edge1S powered by Rockchip RK3399Pro for AI applications. The company has now launched the three boards and accessories through an Indiegogo crowdfunding campaign. I’ve already covered the two RK3399 boards in previous post, and  the RK3399Pro based Khadas Edge-1S (2GB RAM, 2x MIPI-CSI, …) will be similar to Edge board but with , so instead I’ll have a closer look at the specifications for Khadas Captain carrier board for Khadas Edge / Edge-1S: Edge connector – 314-pin MXM3 connector for Khadas Edge / Edge-1S Storage – M.2 …

Khadas is Working on more RK3399 / RK3399Pro Boards, Projector Development Kit, AR Kit

Khadas Edge-V vs Khadas Edge

Shenzhen Wesion had already unveiled their Khadas Edge board that works both as a system-on-module and a standalone SBC thanks to an MXM3 connector on one side, and traditional HDMI and USB ports on the other. The Rockchip RK3399 board will be launched on Indiegogo a little later. But the company is working on a few more boards and development kits all based on Rockchip RK3399 or the upcoming RK3399Pro processor with neural processing unit (NPU) for AI workloads acceleration. First we have Khadas Edge-V, very similar to Khadas Edge but with a 40-pin IO header replacing the MXM3 connector, and following Khadas VIM form factor and ports, so for example we get an Ethernet port as well as an extra USB 3.0 port instead of USB 2.0 on Edge. As mentioned in Khadas Edge announcement, the company is also working on Khadas Captain carrier board with MXM3 socket. So we have three options for development, and while AFAIK the company …
