ENGINEERING & SOFTWARE

Designed by Digital Data Software, LLC. Powered by KingSail Software.

SeaHAT boards are designed by Digital Data Software, LLC and integrate KingSail Software frameworks adapted to Raspberry Pi marine interfaces.

KingSail Software frameworks

01 / Target capabilities

Marine interfaces for an embedded computer

The initial concept covers the interfaces commonly needed in vessel data acquisition and navigation projects. The final channel count, connectors and electrical architecture remain to be specified.

NMEA 2000

CAN-based marine network connection; controller, transceiver, isolation, termination and power behavior to be engineered.

NMEA 0183

Serial marine data connectivity; input/output count and electrical interfacing to be confirmed.

GPS / GNSS

Position and timing input path, with receiver topology and antenna interface under evaluation.

SeaTalk integration

Selected legacy or SeaTalk NG interoperation paths to be assessed, with proper protocol and electrical adaptation.

02 / Host ecosystem

Raspberry Pi 3, 4 and 5

The proposed SeaHAT targets the Raspberry Pi ecosystem through the familiar expansion-header concept. Electrical compatibility, mechanical fit, Linux drivers and HAT identification are separate qualification tasks for each Pi generation.

Integration checklist

  • GPIO assignments, bus controllers and device-tree overlays.
  • Power and protection appropriate to marine installations.
  • CAN / serial interface electrical verification.
  • Application-facing NMEA and Signal K data paths.
  • Mechanical compatibility and enclosure integration.
SeaHAT is a product concept, not a released Raspberry Pi accessory. Raspberry Pi and Bareboat Necessities OS are third-party names; integration is an objective to validate.
