ESP32 development board with OV2640 camera. If you use other camera, edit sdkconfig.default. From the left:
ESP-IDF V5.0 or later. ESP-IDF V4.4 release branch reached EOL in July 2024.
For AiThinker ESP32-CAM, you need to use a USB-TTL converter and connect GPIO0 to GND.
ESP-32 | USB-TTL |
---|---|
U0TXD | RXD |
U0RXD | TXD |
GPIO0 | GND |
5V | 5V |
GND | GND |
git clone https://github.com/nopnop2002/esp-idf-http-camera
cd esp-idf-http-camera
idf.py set-target {esp32/esp32s3}
idf.py menuconfig
idf.py flash monitor
For AiThinker ESP32-CAM, Change GPIO0 to open and press the RESET button.
Set the following items using menuconfig.
You can connect using the mDNS hostname instead of the IP address.
You can use static IP.
You can choose the file name on the HTTP server side from the following.

Large frame sizes take longer to take a picture.
You can choose one of the following shutter methods
CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=y
Shutter is a GPIO toggle
Initial Sate is PULLDOWN The shutter is prepared when it is turned from OFF to ON, and a picture is taken when it is turned from ON to OFF.
Initial Sate is PULLUP The shutter is prepared when it is turned from ON to OFF, and a picture is taken when it is turned from OFF to ON.
I confirmed that the following GPIO can be used.
GPIO | PullDown | PullUp |
---|---|---|
GPIO12 | OK | NG |
GPIO13 | OK | OK |
GPIO14 | OK | OK |
GPIO15 | OK | OK |
GPIO16 | NG | NG |

ESP32-CAM by AI-Thinker have flash light on GPIO4.
When you use ESP32S3-WROVER CAM, you need to set the PSRAM type.
ESP32 works as a web server. You can view the pictures taken using the built-in WEB server. Enter the ESP32's IP address and port number in the address bar of your browser. You can connect using mDNS hostname instead of IP address.
