Dear Rui/ Sara,
There is no ESP32 expressif system in the board manager when doing steps before uploading the codes into the
ESP 32-CAM board. Thus there is no ESP32 board to select from the board list and unable to proceed with your
ESP32-cam course. Please help and advise what happen. Thanks.
What version of Arduino IDE are you using?
Did you go to File > Preferences and add the Boards URL in the “additional boards Manager URLs” field? As shown below:
Thank you for your help. I am using arduino IDE version 1.8.12. I found my mistake for typing “expressif ….”, it should be “espressif …. “. The board list shown esp32 already. I am able to continue the course now.
