#	Part	Qty	What it does
1	Bare PCB	2×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2	Compute SoC Module	1×	System-on-chip compute module carrying the application processor, memory, and storage that runs the device's operating system and user interface.
3	Balise Antenna	1×	Under-frame antenna powering and reading trackside balise transponders.
4	Odometry Sensor	2×	Doppler radar and tachometer set giving safe speed and distance.
