Processor Board parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat 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 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.
3 Power Management IC 1× Battery charger and multiple voltage regulator.
4 SMD Passive (R/C/L) 30× 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 2× 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.
