ModalAI Flight Core v1
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The ModalAI Flight Core v1 (Datasheet) is a flight controller for PX4, made in the USA. The Flight Core can be paired with ModalAI VOXL (Datasheet) for obstacle avoidance and GPS-denied navigation, or used independently as a standalone flight controller.
Flight Core is identical to the PX4 Flight Controller portion of VOXL Flight (Datasheet) which integrates the VOXL Companion Computer and Flight Core into a single PCB.

PX4 Firwmare Compatibility
Flight Core v1 is fully compatible with the official PX4 Firmware from PX4 v1.11.
ModalAI maintains a branched PX4 version for PX4 v1.11. This includes UART ESC support and improvements in VIO and VOA that are planned to be upstreamed.
More information about the firmware can be found here.
QGroundControl支持
This board supported in QGroundControl 4.0 and later.

Quick Start
安装方向
The diagram below shows the recommended orientation, which corresponds to ROTATION_NONE starting with PX4 v1.11 (and on the ModalAI-maintained PX4 v1.10 branch)
For PX4 v1.10 stable releases from QGroundControl use ROTATION_YAW_180 for the above orientation.
