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.

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