freenove_esp32_wrover_board's Issues

Wrong Label assignment in picture

I think there is a little bug in the picture:

https://github.com/Freenove/Freenove_ESP32_WROVER_Board/blob/main/ESP32_Pinout.png

My understanding is that all GPIOs that have a dash are for the camera. On the right side (Pin 4, 6, 18, 19, 21, 22, 23) the PINs are correct. On the left side, they are offset.

Please provide settings for platform.io

Was not able to find the right settings for PIO after 2 hours. No infos if I google for it.

Relevant settings:

board=
board_upload.flash_size=
board_build.partitions=
...

Can you share where you got the Fritzing design from?

Schematic

Great work on the board. I have deployed my own object detection classifier to the board. Could you please provide a schematic for the board? I would also appreciate specs on the landing pattern for the pins. Thank you!

sdcard with camera , SD card initialization failed!

arduino 2.1, esp2.0.7
sdcard alone ok
connected as vspi

with camera compilation ok, but running = SD card initialization failed!

any ideas ?

Detected Camera Not Supported

Hi FreeNove,
I got 5 pieces of this model from AliExpress (https://www.aliexpress.com/item/1005004445001353.html), and I tried some of the examples you have in the tutorial.
I got the same error:
[E][camera.c:1113] camera_probe(): Detected camera not supported.
[E][camera.c:1379] esp_camera_init(): Camera probe failed with error 0x20004
[E][TeleView.ino:187] setup(): Camera init failed with error 0x20004

can you please advise on how to address the issue ?

Available GPIO pins that can be used while using the camera

Hi. I want to add an external SD card reader to my project and need to know which GPIO pins I can use for this.
In the pinout image there doesn't seem to be more than two unused GPIO pins.
This doesn't seem correct.
Would you please help me to know which pins I should use?

Using an SD card with the Freenove ESP32-WROVER-DEV

I would like to find a code similar to the 'ESP32-CAM Take Photo and Save to MicroSD Card' example shown below with the AI Thinker ESP32CAM model. I have some additional sensors that I would like to add to my project to trigger the camera however I have not been able to successfully find anyone who has successfully developed this. The AI Thinker is not optimal for my purposes given that I need additional GPIO pins but any help on this would be greatly appreciated.
