System LEDS Indicators:
– Red (PWR) - Solid light when DC power is supplied
– Blue (left, SLEEP) - turns off only when the system enters into suspend mode
– Blue (right, PMIC) - turns on only when the major power rails are working
– Amber (SATA) - Flashes when SATA data transfers
– Green (NVMe) - Flashes when NVMe data transfers
Active Cooling Fan Connector (12V 4-pin, PWM input + TACHO output)
– Active Cooling Fan is optional
– Connector (4-pin, 2.54mm pitch)
Power DC jack : outer (ground) diameter 5.5mm, inner(positive) diameter 2.1mm
DC 14V ~ 20V (up to 60W)
– DC 15V/4A power adapter is recommended if you don't use two 3.5“ HDDs
– DC 19V/7A power adapter is recommended if you two 3.5” HDDs together
Power consumption:
– IDLE : ≃2.5W
– CPU Stress : ≃15W
– CPU+GPU Stress : ≃18W
– Power-off : ≃0.25W
– Suspend : ≃0.6W

Note that you have to connect an HDMI-CEC adapter board to the 24-pin header to use the HDMI CEC function. The HDMI-CEC boards are sold by 3rd parties.

ODROID boards do not support the hotplug function of storage devices, and replacing SATA, eMMC, or NVMe while the system power is on will cause serious damage to the board and devices.

Power consumption

We used our SmartPower3 (see https://www.hardkernel.com/shop/smartpower-iii/) to test and measure the ODROID-H3 power consumption while performing specific activities. We used an M.2 NVMe storage device, 4K HDMI monitor, Ethernet cable and USB combo keyboard + mouse while measuring the power consumption. The table shown below and its corresponding chart detail the power consumption we witnessed:

Activity Power Consumption in Watt
Power Off 0.21
Ubuntu Desktop Booting 12.36
Desktop Idle 2.52
CPU stress 14.17
4K YouTube play on Chrome Browser 12.02
WebGL aquarium demo on Chrome Browser 10.00
WebGL + CPU Stress 16.38
Power Off 0.21
Sleep (Suspend to RAM) 0.85

  • Two different 4K YouTube videos play flawlessly and simultaneously with Chrome browser on Ubuntu 22.04 desktop.

  • The monitor on the left shows Ubuntu Desktop host OS and the one on the right shows Windows 10 running as a guest OS, using the hardware virtualization VT-x technology.


  • The monitor on the left shows the PCB designing KiCAD application running in Ubuntu while the monitor on the right shows the Edge browser in Windows running as a guest OS.

The ODROID-H3 and H3+ use a PC standard 12V PWM 4-pin connector instead of the proprietary 5V mini connector used on the H2/H2+.
Therefore, anyone can install a third-party cooling fan that can be easily purchased in the market.
