LPSTK-CC1352R: Sensors Power Enable Pins?

Markel Robregado

Part Number: LPSTK-CC1352R

Hi,

I just want to confirm if these pins below are really used to enable/disable power to the sensors. I checked the schematic diagram and those pins are not connected. Those pins are not shown as used at the Quick Start Guide.

CONFIG_GPIO_OPT_PWR DIO29
CONFIG_GPIO_HDC_PWR DIO24
CONFIG_GPIO_DRV_PWR DIO26

Hi,

Yes you are right, those pins are not used to enable/disable power on LPSTK-CC1352R. All sensors are powered directly from VDD.

Thanks. But, with the I2C Sensors and SPI External Flash, power consumption must be high.

Hi,

All sensors and flash have a sleep mode where the current consumption is in the sub uA range.
