Re: Achieving low power consumption with Freertos

ok super,
So, without any bluetooth, I should be able to achieve a few mA instead of 20mA with automatic light sleep and freertos ?
is there an example with automatic light sleep somewhere that I could use as a starting poing ?
any thanks,
Thierry

Achieving low power consumption with Freertos

Hello I have developped a custom board embedding a WROVER-B module. In Deep sleep mode, it consumes approx 500 microAmps. But I cannot use deep sleep nor light sleep mode in my application since I will need to activate BLE to be in permanent scanning mode. So far my application is consuming 20mA whi...

Hardware Design Guidelines for ESP32-WROVER-B

Dear Espressif team I am developping a board based on ESP32-WROVER-B Module.

Namely, it is recommanded to avoid placing any compon...

SD card connexion to a WROVER-B

Hello

It is mentionned in the WROVER-B Datasheet that GPIO6-11 (SD card interface) should not be used. But they are used in the WROVER dev kit schematics to connect an SD Card. Is this normal ?

What is the proper way to connect an SD Card to a WROVER-B module ?

Many thanks
Thierry
