3.2 LPSTK-CC1352R

The LPSTK-CC1352R contains multiple sensors, like the OPT3001 light sensor, HDC2080 Temperature and Humidity Sensor, DRV5032FB Hall Effect sensor and an accelerometer. When testing the current consumption for these sensors, the other sensors will be in standby mode, consuming a small amount of power.
