Overview
The Waveshare ESP32-S3-CAM-OV5640 is an AIoT development board combining camera, audio, and wireless capabilities in a single compact package. 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.
