Seeed Studio XIAO ESP32-S3 Sense
Seeed Studio XIAO ESP32-S3 Sense has a 5-10 day lead time before dispatch. Order will only be sent once all items are available for delivery.
Seeed Studio XIAO ESP32-S3 Sense combines the dual-core ESP32-S3 chip with an onboard camera and digital microphone, built for embedded machine learning applications like voice recognition and vision AI. It supports both Wi-Fi and Bluetooth Low Energy, and pairs 8MB PSRAM and 8MB flash with an external SD card slot for storing captured data.
Onboard Camera and Microphone for Embedded ML
A detachable camera sensor captures up to 2048x1536 resolution and is compatible with both the OV3660 and OV5640 sensors, alongside an integrated digital microphone. Combined with pre-trained AI models from SenseCraft AI for no-code deployment, it's well suited to vision and audio-based ML projects without needing to train a model from scratch. Note that current stock may ship with either an OV2640 or OV3660 camera sensor as Seeed transitions to the newer, lower-power OV3660.
Storage and Connectivity
Onboard 8MB PSRAM and 8MB flash are paired with a microSD card slot supporting up to 32GB FAT storage, giving you room to log images, audio, or sensor data locally. Wi-Fi and Bluetooth Low Energy 5.0 are both built in, with communication over 100m or more possible when paired with a U.FL antenna.

An antenna is included in the box, though if you need extra range for your project, our 2.4GHz Wi-Fi Antenna is compatible with the XIAO ESP32-S3 Sense. Prefer plug-and-play? Grab the pre-soldered XIAO ESP32-S3 Sense instead. Don't need the camera and mic? See the standard XIAO ESP32-S3.
