EtCO2 Capnography Module 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 NDIR CO2 Optical Bench 1× NDIR optical bench
4 Blower Motor 1× Sample aspiration pump
5 CO2 Sampling Line + Water Trap 1× Disposable line + water trap
6 SMD Passive (R/C/L) 55× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
