Highlighted Features

Dual-Channel CAN Bus Logging

Configure loggers in the AutoPi Cloud to capture full CAN-FD traffic from both interfaces simultaneously. Remotely adjust bitrate, enable CAN bus termination, configure bus auto-detection, and more — all without physical access to the device.

Flexible Storage Endpoints

Define where your data goes. Route captured data to Amazon AWS S3, store it locally on the onboard eMMC, or write it to an external USB flash drive. Storage endpoints are fully configurable from the cloud.

On-Device CAN Bus Decoding

Offload CAN decoding to the edge device rather than relying on expensive cloud-side processing. Upload your proprietary DBC files to decode raw CAN data directly on the device and receive clean, structured data in the cloud.

Remote Live Debugging

Use Tailscale to securely connect to the CAN-FD Pro from anywhere and perform live debugging and real-time CAN bus interaction. Deploy custom software using Docker images directly to the device.

Advanced CAN Bus Filtering

Set up precise pass and block filters based on CAN message IDs to control exactly which frames are captured and transmitted. Reduce bandwidth usage and focus on the data that matters most.

Data Enrichment and Encryption

Combine CAN bus data with additional sources — such as onboard IMU and GPS — or integrate external sensors for a richer dataset. Encrypt and cryptographically sign your data using the onboard NXP SE51 secure element.
