Doing so will also put you at risk of damaging the lens or getting dust on the surface of the image sensor.įor the ESP32-CAM, Arducam decides to tackle these problems with three infallible solutions. Inability for Night Vision: If you want to use IR LEDs with the camera together for low light or night vision projects, there’s no other way but to manually unglue/unscrew the lens and remove the IR-blocking filter from the bottom. Short Cable Length: The ribbon of the stock camera is just way too short to let anyone change the orientation of the camera without rotating the board. Narrow field of view: The lens on the stock module only provides a 65-degree FoV, which is far less than what we actually need for home/desk bench/etc. GND is the ground pin.Although the ESP32-CAM can be a good bargain and has big potential for IoT-related projects, it’s not a perfect board, especially on the camera part, the 2MP OV2640 camera that comes with it has quite some limitations.
The 3V3 pin is the output from the on-board voltage regulator you can get up to 600mA from it. The VIN pin can be used to directly power the ESP32 and its peripherals, if you have a regulated 5V power supply. There are two power pins: the VIN pin and the 3V3 pin. The strapping pins function normally after reset release, but they should still be used with caution. However, if peripherals are connected to these pins, you may encounter issues when attempting to upload new code or flash the ESP32 with new firmware, as these peripherals prevent the ESP32 from entering the correct mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins, as the board puts them in the correct state for flashing or boot mode. Depending on the state of these pins, the ESP32 will enter BOOT mode or FLASH mode at power on. These pins are used to put the ESP32 into BOOT mode (to run the program stored in the flash memory) or FLASH mode (to upload the program to the flash memory).
