Power Control Unit parts diagram: 1 bare PCB, 2 power MOSFET, 3 relay, 4 SMD passive (R/C/L), 5 connector. 555 parts in 5 top-level items. — Power Control 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	3×	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	Power MOSFET	28×	Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives.
3	Relay	10×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
4	SMD Passive (R/C/L)	500×	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	14×	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.
