Key Onboard Components & Layout

  • OV2640 Camera Sensor: 2MP camera mounted via FPC ribbon connector. Offers resolution up to 1600×1200 pixels.
  • MicroSD Card Slot: Mounted directly under the camera module for saving captured photos, video clips, or logs.
  • High-Brightness Flash LED: Ultra-bright white LED located on the lower right corner, driven by GPIO4.
  • Reset Button & Pin Headers: Exposes power pins (5V, 3V3, GND), UART (U0R, U0T for programming), and GPIOs (IO0, IO2, IO12–IO16).

Applications and Use Cases

  • Smart Home Automation & Video Doorbells: Can be used as a low-cost Wi-Fi doorbell camera, streaming live video feeds to home automation hubs like Home Assistant or mobile apps.
  • Security & Surveillance Systems: Functions as a wireless motion-triggered security camera that saves images/video to an SD card or sends alert notifications over Wi-Fi.
  • AI Vision & Object Recognition: Supports lightweight machine learning models (Edge AI) for facial recognition, QR/barcode scanning, color detection, and object counting.
  • Industrial & Agricultural Monitoring: Deployed for wireless meter reading, crop/greenhouse monitoring, or inventory status tracking in remote areas.
  • Timelapse Photography: Programmed to take periodic snapshots and store them on the SD card for building long-term time-lapse videos.
  • Robotics & Wireless Vehicles: Acts as a primary camera module for FPV (First-Person View) remote-controlled cars, drones, or autonomous mobile robots.
