Orientation

The following is a ‘top down’ view of the Flight Core depicting the orientation. Starting in PX4 v1.11, the orientation is updated to better align with the usage of the VOXL-Flight. The following is a ‘top down’ view of the Flight Core depicting a ROTATION_NONE setup.

Power Supply

Recommended

A 5VDC supply is required to power the Flight Core. The FC-PM Power Module board is recommended, which provides battery voltage and amperage monitoring through an I2C interface when connected to J6 using the MCBL-00003 cable.

Other connectors also allow a 5VDC supply to be connected (see connectors page )

• J6 - recommended, provides I2C interace for monitoring
• J1/J4/J5

Power Usage

NOTE: The following is preliminary data.

Test configuration:

• Using a 5VDC supply
• Using PX4 this commit
