Main Processor Board parts diagram: 1 compute SoC module, 2 GPS/GNSS receiver, 3 microSD card slot, 4 NMEA 2000 interface, 5 bare PCB, 6 SMD passive (R/C/L), 7 connector. 11 parts in 7 top-level items. — Main Processor Board parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Compute SoC Module	1×	DSP and chartplotter application
2	GPS/GNSS Receiver	1×	Multi-constellation receiver with internal antenna providing position at 10 Hz for charting and trail marking.
3	microSD Card Slot	1×	microSD chart/log storage
4	NMEA 2000 Interface	1×	CAN transceiver linking the unit to the vessel network for engine, AIS, and autopilot data.
5	Bare PCB	1×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
6	SMD Passive (R/C/L)	1×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
7	Connector	5×	Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
