Abstract (en)
A circuit unit for an aerosol generating device includes: a heater connector to which a heater that heats an aerosol source by consuming electric power supplied from a power supply is connected; a controller that includes a first communication terminal and a second communication terminal for serial communication and that controls supply of the electric power from the power supply to the heater; a first IC that is separate from the controller and that includes a third communication terminal for serial communication; a second IC that is separate from the controller and from the first IC and that includes a fourth communication terminal for serial communication; a first communication line that connects the first communication terminal and the third communication terminal with each other; a second communication line that connects the second communication terminal and the fourth communication terminal with each other; a first substrate; and a second substrate that is separate from the first substrate and that is spaced apart from the first substrate, the controller and the first IC are mounted on the first substrate, and the second IC is mounted on the second substrate.
