ESP32 Forum

Hello everyone!

I am looking to use ESP32-S3 in an industrial monitoring device which reads data over sensors (STM MEMS sensors) using SPI. I have checked the current consumption of the board when doing basic reads on the SPI peripheral when the device acts as the master, and the current comes to around 31mA. The application would be a battery operated one hence I was hoping to achieve something below 10mA.
It would be great if someone can give me suggestions on achieving this. The aim of the process is to sample data from the sensor and store it on flash.

Thanks a lot in advance.

UPDATE: I realized the high current consumption was due to the fact that I was using the development board. I was able to take out the LED, and short the USB-UART bridge, which then lead me to the expected current consumption values.
