# PX4 Firmware Compatibility

# voxl-dev branch

ModalAI is actively working on a branched PX4 version (opens new window) that can be used.

As VOXL 2 runs Ubuntu, the production releases of PX4 for VOXL 2 are distributed through apt package management (opens new window) and the VOXL SDK (opens new window).

More information about the firmware can be found here (opens new window).

# main branch

PX4 mainline support is a work in progress (currently started here (opens new window)).

# QGroundControl Support

This board supported in QGroundControl 4.0 and later.

# Availability

# Quick Start

Quickstarts from the vendor are located here (opens new window).

# VOXL SDK

VOXL SDK (Software Development Kit) consists of the open source voxl-px4 (opens new window), core libraries (opens new window), services (opens new window), tools (opens new window), utilities (opens new window), and build environments (opens new window) that ModalAI provide to accelerate the use and development of VOXL compute boards and accessories.

VOXL SDK runs on VOXL, VOXL 2 and RB5 Flight!

The source code for projects within VOXL SDK can be found at https://gitlab.com/voxl-public, alongside build instructions.

# Connectors
