Power Distribution Unit parts diagram: 1 bare PCB, 2 microcontroller, 3 relay, 4 SMD passive (R/C/L), 5 connector, 6 wire bundle. 2,487 parts in 6 assemblies. — Power Distribution Unit 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	Bare PCB	4×	Bus, switching and control boards
2	Microcontroller	2×	Load monitoring and control
3	Relay	32×	Solid-state and EM load switches
4	SMD Passive (R/C/L)	2400×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
5	Connector	48×	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.
6	Wire Bundle	1×	Internal box wiring
