The sensors on the Nordic Thingy:53™ can be powered down through a load switch (U19) which is connected to P0.31 on the nRF5340 System on Chip (SoC).
Note: In the Nordic Thingy:53 boards files, the
SENS_PWR_CTRL pin (P0.31) is pulled high by default.
The following schematic describes the sensor power control circuit.
