ARK Pixhawk Autopilot Bus Carrier
The ARK Pixhawk Autopilot Bus (PAB) Carrier is a USA-built flight controller carrier board, based on the Pixhawk Autopilot Bus open source standard (opens new window).
The PAB form factor enables the ARK PAB Carrier to be used with any PAB-compatible flight controller, such as the ARKV6X.
