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

No they arent. It uses 2,4,12-15,21 which is the second sdio interface aka HS2.
