 ## Notes
-If your target board is a ESP32, I recomend 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 OV5640 pinout is compatible with boards designed for the OV2640 but the voltage supply is too high for the internal 1.5V regulator, so the camera overheats unless a heat sink is applied. For recording purposes the OV5640 should only be used with an ESP32S3 board. Frame sizes above FHD framesize should only be used for still images due to memory limitations.
