The Nordic Thingy:91 X™ has two buttons for user input.
Button 1 (SW3) is connected to P0.26 on the nRF9151 System in Package (SiP) (M1). Button 1 is located under the circle on the top part of the casing and can be actuated without removing the casing.
The following figure describes Button 1.
Button 2 (SW4) is connected to P0.24 on the nRF5340 System on Chip (SoC) and acts as a reset button for the nRF9151 SiP when the nRF5340 SoC is programmed with the Connectivity bridge sample. It is connected also to the nPM1300 Power Management Integrated Circuit (PMIC) SHPHLD pin and can be used to exit shipment mode if the nPM1300 PMIC (U11) has been configured to enter this mode. Button 2 is located on the side of the Nordic Thingy:91 X™ PCB. The top casing must be removed to actuate it.
The following figure describes Button 2.
