25 Real-World Projects Using the PiCAN-M Raspberry Pi CAN Bus HAT
Posted by on
The Raspberry Pi has become one of the most versatile platforms for embedded development, and when combined with the PiCAN-M CAN Bus HAT, it becomes a powerful interface for marine electronics, CAN-based systems, and data acquisition applications.
The PiCAN-M board connects a Raspberry Pi directly to NMEA 2000 (CAN bus) and NMEA 0183 networks, enabling developers to build navigation systems, data loggers, and sensor gateways with open-source software.
Below is a curated overview of real projects, software platforms, and websites where the PiCAN-M board is used in practical Raspberry Pi systems.
Marine Navigation Systems
1. Signal K marine data server
A Raspberry Pi with PiCAN-M can run Signal K, an open marine data platform that collects and distributes vessel data.
Typical data sources include:
- GPS position
- wind instruments
- depth sounders
- engine telemetry
Signal K then publishes the information to dashboards, navigation software, or mobile devices.
