The ESP32 CAM has a huge active online community. This means a user can easily access tutorials, forums, and resources. They offer support and share project ideas. This community can help users quickly solve issues and learn from others' experiences.
When choosing an ESP32 CAM board, buyers will consider the following factors:
Camera quality
To seamlessly cater to customers with different needs, buyers should get ESP32 CAM boards with different camera qualities. Ideally, buyers should look for boards with a minimum resolution of 2MP. This ensures customers get quality images and videos. At this stage, buyers can also consider boards with optional camera modules. This feature enables customers to upgrade or change the camera based on their requirements.
Wi-Fi and Bluetooth functions
One of the main advantages of ESP32 CAM is its connectivity features. Therefore, when selecting boards, buyers should ensure they have the full capability of the Wi-Fi and Bluetooth features of the module. In particular, they should focus on modules with Bluetooth 5. This version offers extended range and improved speed. The functions are particularly useful for customers intending to use the board for IoT applications.
Additional features
Some ESP32 CAM boards include useful additional features. For instance, built-in microSD card slots, LED, or battery connectors.
