How to Power

Power supply: 12Vdc +/-5% , ≥5A, via DC 12V IN Port of X885, recommend to Geekworm DC5521 12V/5A Power adapter US/EU plug
Ports & Connectors: DC jack - 5.5x2.1mm

Important Note: Please use high quality power adapter, the low quality PSU may damage the X885 board and not recognized the HDD.

Warning about power supply:

Don't use that adjustable voltage power supply.
Don't use the same power supply used on LED strips.

The above two are absolute garbage power supply, can not be used!!!

About SSD/HDD

Do not recommend using Samsung hard drives, please use hard drives of other brands.
As with all SSDs, new SSD/HDD must be formatted before use.
Older SSD/HDD drives with less efficient flash media may not perform as well as newer drives.
A microSD card is required for forceing the Raspbian OS to use the HDD/SSD for its "root" partition
