esp32-camera

esp32-camera is the camera model that supports all cameras that work with Espressif’s esp32-camera drivers including:

OV2640
- Datasheet
- 1600 x 1200, Color, ¼” lens
- You can use a cam ribbon adapter to connect to your esp32 board
OV3660: an m5 camera timer module
- Datasheet
- 2048 x 1536, Color, ⅕” lens

Software requirements

To use this model, you must follow the Set up an ESP32 guide, which enables you to install and activate the ESP-IDF. When you create a new project with cargo generate, select the option to include camera module traits when prompted. Finish building and flashing custom firmware, then return to this guide.

Data management not supported

The esp32-camera camera model does not currently support the data management service.
