+**配置摄像头传感器：**
+
+> **注意：** 确认摄像头传感器型号，确定型号在 esp_cam_sensor 支持的范围内。当前板子用的是 OV2640，是符合支持范围。
+
+在 menuconfig 中按以下步骤启用对应型号的支持：
+
+1. **导航到传感器配置：**
+   ```
+   (Top) → Component config → Espressif Camera Sensors Configurations → Camera Sensor Configuration → Select and Set Camera Sensor
+   ```
+
+2. **选择传感器型号：**
+   - 选中所需的传感器型号（OV2640）
+
+3. **配置传感器参数：**
+   - 按 → 进入传感器详细设置
+   - 启用 **Auto detect**
+   - 推荐将 **default output format** 调整为 **YUV422** 及合适的分辨率大小
+   - （目前支持 YUV422、RGB565，YUV422 更节省内存空间）
