ESC parts diagram: 1 bare PCB, 2 power MOSFET, 3 gate driver IC, 4 microcontroller. 9 parts in 4 top-level items. — ESC 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	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.
2	Power MOSFET	6×	Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives.
3	Gate Driver IC	1×	Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT.
4	Microcontroller	1×	Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
