Khadas Edge2 ultra thin SBC is powered by Rockchip RK3588S processor

Khadas Edge2 SBC

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 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 […]

Khadas VIM4 – An Amlogic A311D2 SBC with 8GB RAM, Wi-Fi 6, HDMI input & output

We’ve just written about the Amlogic A311D2 processor with some pretty interesting features, and Khadas VIM4 will be one of the first single board computers equipped with the latest octa-core processor, succeeding the company’s earlier Khadas VIM3 board powered by an Amlogic A311D hexa-core processor. Khadas VIM4 makes good use of the extra memory allowance with faster 8GB LPDDR4 RAM, and also offers 32GB eMMC flash, Gigabit Ethernet, WiFi 6, 4Kp60 HDMI input and output, independent USB 3.0, and PCIe (via M.2 socket) interfaces, and more. Khadas VIM4 specifications with bold highlights showing the differences with the VIM3 Pro model: 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, NPU shown as TBD possibly due to license requirements System Memory- 8GB LPDDR4X @ 2112 MHz Storage – 32GB eMMC […]

Khadas Tone 2 Pro mini desktop Hi-Fi system supports MQA decoding, balanced RCA outputs

Khadas Tone high-resolution audio board was introduced in 2018 for audiophiles wanting to design their own DIY HiFi system using Khadas VIM/VIM2 SBC, or connect it the USB version of the board to other single board computers. The company is now about to launch Khadas Tone 2 Pro mini desktop Hi-Fi system based on the same ESS ES9038Q2M DAC, but a faster XMOS XU216 capable of handling MQA decoding, and equipped with balanced RCA outputs, as well as an I2S USB-C port. Khadas Tone 2 Pro key features and specifications: Multicore MCU – XMOS XU216 with 16 real-time logical cores on 2x xCORE tiles; up to 1000 MIPS DAC – ES9038Q2M 32-bit stereo mobile audio DAC Amplifiers – 4x OPA1612 operational amplifiers, 3x buffer amplifiers Seamless hardware MQA decoding Native DSD512 decoding, PCM decoding up to 32Bit/384kHz. Left and right balanced RCA jacks for transmitting a balanced analog signal via […]

Khadas VIM3 & VIM3L SBC’s become Android reference boards

If you need to work on the very latest development version of Android or AOSP, you can either get one of the supported phones such as Google Pixel 5,  one of the reference boards for Android which should be better for development and also fairly cheaper. We previously reported about Hikey, Hikey960, and DragonBoard 845c single board computers being part of the short list of reference boards for the Android Open-Source Project (AOSP), but Amlogic powered Khadas VIM3 and VIM3L have recently been added to the official devices page which makes them the first AOSP reference boards with a dedicated NPU / AI accelerator. As a quick reminder, Khadas VIM3 is the most powerful board with an Amlogic A311D hexa-core Cortex-A73/A53 processor with up to 4GB RAM and 32GB flash, and Khadas VIM3L is the light version with an Amlogic S905D3 quad-core Cortex-A55 processor with 2GB RAM and 16GB flash.

Coronavirus Update: Many Chinese Companies to Stay Closed at Least until February 17

About 10 days ago, I wrote a post about the impact of the coronavirus on manufacturing and shipping from China. At the time, we knew the Chinese New Year “holiday” was extended until February 10 in order for the authorities to contain the outbreak. That meant manufacturing would be impacted, and not much will ship from China during that time period. At the time, we were also told packages shipped from China were safe as it took several days and the virus would just die off on the way. But there have been some updates since then. First, a new study shows the coronavirus may stay alive on surfaces like metal, glass or plastic for up to 9 days at room temperature. So I’m not sure what that means for packages sent via courier services like FedEx or DHL. The previous link offers some solutions: … but can be efficiently […]

Krescue for Khadas VIM Boards Enables Backup/Restore of eMMC flash, Access to the Terminal, and More

Sometimes things go wrong, and you need a way to recover your system, either by restoring a backup or accessing your system to check it out and hopefully fix the issue. Krescue is a minimal firmware image (21MB compressed) for Khadas VIM boards designed to do just that, and more. Some of the highlights of Krescue firmware image include: Full eMMC flash dump/backup to Micro SD card, USB, or LAN host. Restore the compressed dump (.img.gz) into an eMMC on the same device or another device Rescue shell for expert users. Shell access via UART, USB network, and Web browser You’ll find Krescue for Khadas VIM1, VIM2, VIM3 and VIM3L on Khadas website which can be flashed to a MicroSD card using balenaEtcher. You can then insert the card into your board, and boot into maskROM mode to access the menu above, and control it with the IR remote control […]

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 […]
