 At the moment, this is a micropython user module, but it might get in the micropython repo in the future.
 The API is stable, but it might change without previous announce.

 - If your target board is a ESP32, I recommend using IDF >= 5.2, since older versions may lead to IRAM overflow during build. Alternatively you can modify your sdkconfig-file (see [issue #1](https://github.com/cnadler86/micropython-camera-API/issues/1)).
 - The driver requires PSRAM to be installed and activated.
 - Most of the precompiled firmware images are untested, but the only difference between them are the target architecture and pin definitions, so they should work out of the box. If not, please raise an issue.
+- Every sensor has its own ranges and settings, please consult the respective specifications.
