ModalAI VOXL Flight
PX4 v1.11WARNING
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The ModalAI VOXL Flight (Datasheet) is one of the first computing platforms to combine the power and sophistication of Snapdragon with the flexibility and ease of use of PX4 on an STM32F7. Made in the USA, VOXL Flight supports obstacle avoidance and GPS-denied (indoor) navigation fused with a PX4 flight controller on a single PCB.
INFO
This flight controller is manufacturer supported.
