Hi.
You have to double-check the pins.
Most times, you’ll have to assign them yourself manually.

Is this the one you’re using: https://randomnerdtutorials.com/getting-started-freenove-esp32-wrover-cam/?
Or do you have another version?
Regards,
Sara

Hi,

I’m trying my first ESP32-Cam project with a WROVER from Freenove.
When building my application, do I have to define BOARD_WROVER_KIT somewhere so that the compilation of the source code will make the correct assumptions in terms of pins assignment ? (I see #if BOARD_WROVER_KIT several times)
Thanks, B.

If you want to run the ESP32-CAM off 5V it is probably “safer” to put the jumper on the 3V3 position and run a separate Dupont wire from the 5V pin on the programmer to the 5V pin on the CAM.

This way the UART logic levels are at 3V3.

Thanks !!!
I read many sites before land here. You explain the crucial steps. Finally, I could program my board…
Thanks again !.

Hello,
please note: On some clones of the ESP-CAM, Pin1 of the header P1 is not connected to GND.

Hello, I have tried everything possible with various configurations and I always get the following error when viewing the camera image on my local ip:
GET http://192.168.1.106/capture?_cb=1689180938227 500 (Internal Server Error )

Could you help me?

Hi Sara:
Thanks for your fast response. I did not mention it before, but I find your tutorials very useful.
Tried again using the ESP32-CAM-MB and get the following in the Serial Monitor:

rst:0x1 (POWERON_RESET), boot: 0x13 (SPI_FAST_FLASH_BOOT)
config: 0, SPIWP:0xee
clk_drv: 0x00, q_drv:0x00, d_drv:0x00, csd_drv: 0x00, hd_drv: 0x00, wp_drv: 0x00,
mode:DI=,clock div: 1
load: 0x3ff0030, len:1344
load: 0x0040078000, len: 13924
ho 0 tail 12 room 4
load: 0x0400804, len: 3600
entry 0x400805f0

Then I tried with the CP2102 breakout, not pressing reset at connecting………
Get the same results in Serial Monitor as above.

Next, CP2102, but pressing reset at Connecting……………
1st try:
Error:A fatal error occurred: invalid head of packet (0x65): Possible serial noise or corruption
2nd try:
Error: A fatal error ocurred: unable to verify chip connection (invalid head of packet (0x78): Possible serial noise or corruption.).
Next tried programming with the MB adapter. sketch seems to load ok. Removed camera board from adapter and connected to PC through CP2102, pushed reset and got two print-outs of the sam results as above but with the followig lines added:
E (508) camera: Detected camera not supported
E(508) camera: Camera probe failed with error 0x106 (ESP_ERR_NOT_SUPPORTED)
Camera init failed with error 0x106

Hope you can help me.
Many thanksfor your time.
Best regards
Alfredo Gonzalez

Hi Rui and Sara,
Flashed Blink sketch-OK with CP21o2, CP2103 will not work- but any other sketch for streaming video gives all sorts of errors and none gives de ESP32’s IP address.
Your comments are welcome and appreciated.
Best regards,
Alfredo Gonzalez

Hi there,
i am also using esp32 cam. your territorial has helped me a lot. Today i have a project for using image processing using esp32 can over the live feed i want to use background subtraction on it can you help me a little over it.
if it is possible please recommend similar prjects too for better understanding
