Add SD Card Reader to TTGO T-Journal Camera

Donald asked 4 years ago

Hello,
Has anyone added an SD card reader to the TTGO T-Journal ESP32 camera?

The Journal camera has very few pins. Some GNDs, some 3V, and IO2, IO4, SDA and SCL.

Hi Donald.
I never tried it. You need at least three GPIOs, because the module uses SPI communication protocol.
In theory, you just need to define the pins you are using for SPI.
We have this guide that might be useful: https://randomnerdtutorials.com/esp32-microsd-card-arduino/
It also shows how to set the pins on the code.
Regards,
Sara

Hi Sara, thank you for your quick reply!
That guide looks doable for me. I can define the pins in the sketch. I’ll give it a shot!

I’m wanting to build a PIR-enabled outdoor bird feeder camera. Having a good wifi connection is a must, and an SD card reader. When a bird trips the sensor, it will take a picture per second and save to card. THEN, I need to make it web-enabled to view the stored pics.
