As expected, single-board computer maker Khadas is updating its Edge line of compact computer modules. The new Khadas Edge2 is a 3.2″ x 2.3″ x 0.2″ computer computer featuring a Rockchip RK3588S processor, up to 16GB of RAM and up to 64GB of storage.

First reveled this summer, the Khadas Edge2 will ship in December and it’s now available for pre-order with prices starting at $200 for a Basic model with 8GB of RAM and 32GB of storage or $300 for a Khadas Edge2 Pro with 16GB of RAM and 64GB of storage.

Khadas has been making mini PCs under the Edge brand since 2018, but previous-gen models featured Rockchip RK3399 processors. The new version has a significantly higher-performance RK3588S processor which features:

  • 4 x ARM Cortex-A76 CPU cores @ 2.25 GHz
  • 4 x ARM Cortex-A55 CPU cores @ 1.8 GHz
  • ARM Mali-G610MC4 graphics
  • Neural Processing Unit with support for up to 6 TOPS AI performance
  • Video processing unit with support for 4K/60fps decoding of H.265 or AV1 video and 8K/30fps encoding of H.264 or H.265 video

There’s also a 64 MHz microcontroller for power management and boot device selection, LPDDR4x-2112 memory and eMMC 5.1 storage.

Ports include:

  • 1 x HDMI 2.1
  • 1 x USB 3.1 Type-C
  • 1 x USB 3.1 Type-A
  • 1 x USB 2.0 Type-A
  • 1 x USB-C (for power only)

There’s also a 7-pin pogo pad connector for USB extension, UART debugging, or 5V power output, an onboard RTC battery, two MIPI-DSI display interfaces, three MIPI-CSI headers for use with cameras, and support for an optional Edge2 I/O Expansion module that adds support for an SD card and UART debugging (those features aren’t included in the board itself and require either the expansion board or USB accessories.

Another interesting omission? There’s no 3.5mm audio jack.

The little computer also supports WiFi 6 and Bluetooth, and Khadas says the single-board computer supports multiple operating systems including Ubuntu and Android.

Khadas sells the Edge2 in two configurations. The Edge2 Maker Kit includes the mainboard and two antennas, but no case, while the Edge 2 ARM PC Kit costs an extra $30 and includes a case.

Optional accessories will include a heat sink, active cooling case, USB-C power adapters, and touchscreen displays.

    1. What kind of battery were you planning to use? Most ones you could put on it would die in a couple hours, that is if you weren’t also powering peripherals with it. What do you expect to do with it that a battery on board is useful, given that you can always put a battery next to it and plug in a cable?

      1. That user asks about LiPo connectors on nearly every SBC and Blender performance on nearly every microcontroller with a LiPo connector.

      1. There are real world reviews with a connected display on YouTube. By Eta Prime etc. These are real world reviews, not just headless use or people playing benchmarks all day.

        1. ETA Prime isn’t a reviewer or real-world tester. After blowing up in popularity, he is now sponsored by some of these companies.

          You can notice this by how much restraint he uses when discussing negatives. But when it comes to the positives, he seems to exaggerate and waffle on.

          It’s still entertaining, interesting, and newsworthy. But you should look to other sources for more balanced and unbiased reviews.

          1. All the other sources do it for money! Using the devices for emulation is real world use. Playing benchmarks all day is not real world use or using them headless. The devices comes with display connections, they are there to be used. Even this site’s runs adverts .
