🔧 Features & Specifications
🔧 How To Upload Code To ESP32-CAM
The ESP32-CAM does not have a built-in USB port — you need a separate programmer board to upload code. You can use either of the two options below, both available from Dream RC.
Add ESP32 Board Package to Arduino IDE
Open Arduino IDE → File → Preferences → Add this URL to Additional Boards Manager URLs:https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
Then go to Tools → Board → Boards Manager → Search esp32 → Install esp32 by Espressif Systems.
Select the Correct Board & Settings
Go to Tools → Board → AI Thinker ESP32-CAM. Set partition scheme to Huge APP (3MB No OTA) for camera sketch. Select the correct COM port from your programmer.
Upload CameraWebServer Example
Go to File → Examples → ESP32 → Camera → CameraWebServer. Fill in your WiFi name and password, select CAMERA_MODEL_AI_THINKER, then upload. Open Serial Monitor at 115200 to get the stream URL.
⚙️ Arduino IDE Settings For ESP32-CAM
💡 PSRAM Tip: Make sure PSRAM is enabled in your sketch (
psramInit()) for higher resolution streaming — the 4MB PSRAM is what allows UXGA resolution without crashing.💻 Quick Start — WiFi Camera Stream Example
This example connects the ESP32-CAM to your WiFi and starts a live video stream accessible from any browser on the same network.
ESP32-CAM WiFi Video Stream (CameraWebServer)
// Go to: File → Examples → ESP32 → Camera → CameraWebServer // Then make these changes at the top of the file: // Step 1 — Select your camera model (uncomment this line only) #define CAMERA_MODEL_AI_THINKER // Step 2 — Enter your WiFi credentials const char* ssid = "Your_WiFi_Name"; const char* password = "Your_WiFi_Password"; // Step 3 — Upload, then open Serial Monitor at 115200 baud // You will see something like: // Camera Ready! Use 'http://192.168.1.X' to connect // Open that IP address in your browser to see the live stream!
Open Serial Monitor at 115200 baud after upload to get the stream URL. Works in Chrome, Firefox, and Edge.
