how to power 6DOF v4

Dear all forum member,

I have a issue to deal with as powering the IMU 6ODF v4. Do anyone know how to power IMU 6DOF v4. I ask this question because I got confuse as I read the manual.

In the manual we have:

  • power connector (number 5 in the diagram)

  • programming port and TTL line (number 10 in the diagram controller board)

Where should I supply the power for the board? I have two option to do:

  • 4.2 - 7 Volt to power connector?

or 3.3V to programming port?

I believe that some people have deal with this issue before. It is my hornor to have the suggestion.

Thank you for your attention,

Phuoc Thien,
