Hi.
 
What version of the ESP32 boards version do you have installed?
Go to Tools > Boards > Boards Manager > Search for ESP32 and check the version. You may need to update.
 
Double-check that your microSD card is properly inserted. Have you tried another microSD card project with the ESP32-CAM before?

Hi Sara,
Actually I found an aswer that partially solve it. The board started working again downgrading the board. With 1.0.6 it worked again but the camera did not capture images in UXGA format, just XGA.
I am now trying to go even further back and I am trying to get version 1.0.5 to see if it solves the problem.
I can´t get the LED to stop turning on, a big problem to me.
I´ll keep you posted.
Grato,
Joao

Hi.
Unfortunately, the on-board LED shares a GPIO with the microSD card. So, whenever you write to the microSD card, the LED will turn on….
 
As for the issues with the resolution, with some updates of the ESP32 board core on the Arduino IDE, some features stopped working on the ESP32-CAM, as I think it’s the case of the resolution as well as face recognition.

Oi Sara.
Grato pelo retorno. Posso escrever em português ou devo continuar em inglês?
Por mim não há problema nenhum.
Eu consegui programar tudo sem problemas agora.
Estava chamando a placa errada.
Quanto ao Led, posso remover o Led da placa ou isso afetará o funcionamento dela?
Grato

Acho que não tem problema, mas nunca experimentei.
Depois partilhe os resultados 👍

Oi Sara,
 
Update, sim funciona sem o Led.
Só que não consegui retirá-lo então retirei o transistor que o liga com um ferro de solda de 30W
Consegui também fazer um update de câmera para a OV5640.
Vou continuar estudando.
 
Grato

Ok.
Great!
I’ll mark this issue as resolved.
If you need further help, you just need to open a new question in our forum.

Sara
