How to Wire NMEA 2000 with the PICAN-M Raspberry Pi HAT and Power It Using the Onboard SMPS
The PICAN-M is a marine-grade Raspberry Pi HAT that brings both NMEA 0183 and NMEA 2000 connectivity to your Pi, with the added convenience of an onboard 3 A SMPS (Switch-Mode Power Supply) for powering the Pi itself. This makes it ideal for embedded marine systems using platforms like OpenPlotter or Signal K. In this [...]
Migrating Legacy CAN Systems to Modern Architectures: Practical Steps & Pitfalls
The Controller Area Network (CAN) protocol has been the backbone of reliable embedded communication for decades. From passenger cars to heavy-duty trucks, from industrial machinery to marine electronics, CAN has delivered deterministic, robust, and low-cost networking. But as data demands grow—driven by autonomous features, connected vehicles, and Industry 4.0—Classical CAN’s 1 Mbit/s bandwidth and 8-byte [...]
