The inside is dominated by a aluminum plate with dimples for the Ambarella A5S CPU and the back of the image sensor. The heat sink presses against the outer case, through a squishy thermal interface material (TIM).

The huge round thing is a buzzer. The round PCB board hosts the 2.4Ghz WiFi and bluetooth antennas (there is no 5Ghz).

The infrared LED board sports a plastic frame to aim each LED separately.
