ARK Pixhawk Autopilot Bus Carrier

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The ARK Pixhawk Autopilot Bus (PAB) Carrier is a USA-built flight controller carrier board, based on the Pixhawk Autopilot Bus open source standard.

The PAB form factor enables the ARK PAB Carrier to be used with any PAB-compatible flight controller, such as the ARKV6X.
