It features a 5-megapixel OV5640 autofocus camera sensor with DVP interface capable of 2592x1944 resolution, making it suitable for image capture, object detection, and AI vision applications. The board integrates a complete audio subsystem with dual-microphone array (ES7210 ADC) for noise reduction and echo cancellation, an ES8311 audio codec, and NS4150B 3W Class-D amplifier for speaker output. This combination enables AI voice assistants, intercom systems, and voice-controlled smart home devices. A CH32V003F4U6 RISC-V co-processor provides additional I/O expansion, while the ETA6098 battery management IC supports portable operation from a 3.7V LiPo battery via the GH1.25 connector. The 18-pin FPC display interface supports Waveshare SPI/QSPI LCD screens from 1.47 to 3.5 inches, and a TF card slot provides expandable storage for recordings and image capture. ## Where to Buy - [Waveshare](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fesp32-s3-cam-ov5640.htm&ref=openhardware.directory&product=waveshare-esp32-s3-cam-ov5640&source=md-export) — $16.99 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fesp32-s3-cam-ov5640.htm&ref=openhardware.directory&product=waveshare-esp32-s3-cam-ov5640&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fwaveshareteam&ref=openhardware.directory&product=waveshare-esp32-s3-cam-ov5640&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.espressif.com%2Fsites%2Fdefault%2Ffiles%2Fdocumentation%2Fesp32-s3_datasheet_en.pdf&ref=openhardware.directory&product=waveshare-esp32-s3-cam-ov5640&source=md-export) ## Tags `esp32-s3`, `camera`, `ov5640`, `5mp`, `ai`, `audio`, `microphone`, `voice`, `aiot`, `waveshare` ## Images ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/6a4afcb65441.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/238f7c97a1c4.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/f0beb1e33c0a.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/7da8ca91b2a1.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/a7264b9d1381.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/ae44b95fe916.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/02eabe314af5.jpg) ![Waveshare ESP32-S3-CAM-OV5640](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-esp32-s3-cam-ov5640/b1c13a442b02.jpg) > **Battery Powered:** Li-Po --- [View full device page](https://openhardware.directory/devices/waveshare-esp32-s3-cam-ov5640)
