Overview:

The Holybro Pixhawk Jetson Baseboard is based on the Pixhawk Autopilot Bus open source specification and the NVIDIA Jetson Orin NX/Nano Carrier Board. The Pixhawk Autopilot Bus (PAB) Form Factor enables this to be used with any PAB flight controller such as the Pixhawk 6X.

Features:

• • Combines the power of Pixhawk & Nvidia Jetson in a single board
• • Nvidia Jetson & Pixhawk connected via UART, CAN, and ethernet switch
• • Pixhawk Autopilot Bus (PAB) Form Factor
• • Compatible with Jetson Orin NX & Orin Nano
• • 2x M.@ key for WiFI/Bluetooth & NVMe SSD
