Jump to: navigation, search

The Khadas Edge is a System-on-Module. The Khadas Captain is a matching baseboard.

Technical details

  • Khadas Edge SoM
    • Rockchip RK3399 SoC
      • 2x Arm Cortex-A72 CPU
      • 4x Arm Cortex-A53 CPU
    • STM8S MCU (power management)
    • AP6398S Wifi
  • 40-pin GPIO connector (not Raspberry Pi compatible)

Manual installation

The Edge module itself does not have a UART connector, unlike the GeekBox module.

On the Captain baseboard the serial console is located on pins U_RX (17), U_TX (18) and GND (16/19) near the barrel power connector.

Alternatively you can attach the Edge-IO board and use its RXD, TXD and GND pins.

The baudrate is 1500000. You may need minicom, as screen may have problems with this high baudrate.

$ minicom -b 1500000 -D /dev/ttyUSBx


The module ships with a downstream 2014 U-Boot.

U-Boot v2018.11 does not yet contain a config for this board.


Linux 4.20-rc3 does not yet contain a .dts for this module.
