The Nordic Thingy:53™ has two buttons that are connected to the nRF5340 System on Chip (SoC).
The main button (SW3) is located under the circle on the top part of the casing and used for user input. The other button (SW2) can also be used for user input, but it can be accessed only by removing the top part of the casing. You can activate serial recovery mode by pressing and holding SW2 when power-cycling the device.
The following schematic describes the buttons.
