User manual


Q1: What kind of power supply does X5500 use?

A: X5500 use DC 6V~26V widht voltage input, 55x25 jack, please refer to X830 V2.0#Power Supply(Optional)

Q2: How to solve the heat dissipation problem?

A: Please refer to here: embedded armor aluminum alloy heatsink can solve your problem.

Q3: Does x5500 support safe shutdown?

A: YES, You can use X710 to achieve safe shutdown function.

Q4: Does X5500 support hdd/sdd storage function?

A: Yes, you can use X825/X857/X862/X872/X829 etc. to get storage function.

Q5: Is there a matching case to support X5500?

A: No yes, we look forward to your feedback, we will consider making a shell according to the needs of users.

Q6:Does the X5500 support to use with X735?

A:The X5500 only support to use with the X735 V2.5 VERSION, NOT support other version. And you need need extra one piece 2pin power cable.

The connection is as follow:

  • X5500 - 5V OUT -> X735 – 5V IN
  • X5500 – 5V PWR -> X735 – 5V OUT

PWR-Open, the power supply should be connected to X5500 ONLY.
