==How to Power==
* Please use '''6-24''' power adapter with DC5521 jack to power via X729 DC port.

Important Note: Please use a <span style ="color: red>high quality power supply with surge protection and overvoltage protection!!!</span> Otherwise it is easy to burn the DC chip!

Recommend to use [[PSU60 | Geekworm DC5521 12V/5A Power adapter US/EU plug]]

<span class="tb_red ">Warning about power supply:</span>
# 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!!!
