# ESP32 Camera Driver
|
||||
|
||||
[](https://github.com/espressif/esp32-camera/actions/workflows/build.yml)
|
||||
## General Information
|
||||
|
||||
This repository hosts ESP32 compatible driver for OV2640, OV3660, OV5640, OV7670 and OV7725 image sensors. Additionally it provides a few tools, which allow converting the captured frame data to the more common BMP and JPEG formats.

If you miss-skip-ignore this critical step the camera module will compile but camera logic inside the library will be 'empty' because the Kconfig sets the proper #ifdef statements during the build process to initialize the selected cameras. It's very not optional!
