Freenove ESP32-Wrover CAM vs ESP32-CAM Ai-Thinker The examples that use a microSD card, should also be compatible if using an external microSD card module and adjusting the pin definition on the code. #define PWDN_GPIO_NUM -1īecause this board uses the same camera used in the ESP32-CAM board, the examples for the ESP32-CAM (that don’t use microSD card) should also work with the Freenove ESP32 Camera board by changing the pin definition. The pin definition for the ESP32-Wrover CAM board (Freenove brand) in your Arduino sketches should be as follows (in some of the Arduino examples, this pin definition is under the CAMERA_MODEL_WROVER_KIT definition). When you’re not using the camera, you can use this ESP32 board as a “regular” ESP32 and you can use the camera pins for other purposes. Otherwise, the camera won’t work properly. Note that when you’re using the camera, you can’t connect peripherals to the GPIOs used by the camera. Here’s a table with the connections between the ESP32 and the camera: OV2640 Camera Freenove ESP32-Wrover CAM Board – Camera Pin Definition You can clearly see which pins are being used by the camera, the power pins, PWM pins, ADC pins, etc. The following figure shows the schematic diagram for the ESP32-CAM.There are labels indicating the features of each pin. Flash Flash on and brightness Deep-Sleep: as low Modern-Sleep: as low Light-Sleep: as low Operating temperature: -20 ℃ ~ 85 ℃.Output image format: JPEG (OV2640 support only), BMP, GRAYSCALE.
The ESP32-CAM is a small-size, low-power camera module based on ESP32.
