What You Can Build With This
- WiFi Security Camera: Stream live video to your phone with motion detection alerts using the ESP32-CAM examples.
- Facial Recognition Doorbell: Combine with a server or local processing to identify visitors and unlock doors.
- Time-Lapse Photography: Program periodic captures and save to microSD, ideal for plant growth or construction monitoring.
- QR Code Scanner: Use the camera to read barcodes or QR codes for inventory management or access control systems.
Compatibility
This board is supported in Arduino IDE (install ESP32 board manager), MicroPython, and ESP-IDF. For programming, an external FTDI USB-to-serial adapter is required; connect to U0T/U0R and toggle GPIO0. It operates at 3.3V logic—use level shifters when interfacing with 5V sensors or actuators. Pairs well with I2C devices like OLED displays and BME280 sensors.
Wiring Notes
Connect a 5V FTDI to VCC and GND, TX to U0R, RX to U0T. To enter flash mode, bridge GPIO0 to GND during power-up. The camera ribbon cable inserts into the socket with the contacts facing down; secure the clip without forcing. Use a regulated 5V supply capable of at least 500mA to avoid brownouts during WiFi transmissions.
