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
