ESP32-CAM - A.I. Thinker

The goal of this repository is to centralize information and examples for the ESP32-CAM A.I. Thinker.

Read the board and periferals specifications here.

ESP32-CAM A.I. Thinker usually sells with OV2640 sensor

Examples

• Detect changes and take pictures
• Store pictures using Firebase (Google Storage)
• Store pictures in SD
• JPG via Http server

Running with PlatformIO

To run the examples, make sure to have PlatformIO installed. If you haven't, refer to this tutorial.

Flashing

Requirements

To flash the board you need a USB to TTL dongle.

Also it is very important to use a external power supply. USBs usually do not provide sufficient current which makes the board loops brownout errors.

Wiring
