XIAO ESP32S3 Sense projects and builds
Thumb-sized ESP32-S3 board bundled with an OV2640 camera, digital microphone and microSD support for vision and audio projects.
Why it belongs on the bench
Seeed XIAO ESP32S3 Sense pairs a thumb-sized ESP32-S3 board with a Sense expansion board carrying an OV2640 camera, digital microphone and microSD slot, alongside Wi-Fi, Bluetooth and external-antenna support. Those interfaces fit the catalogue’s browser camera server and TinyML keyword-spotting tutorial, while the SSCMA example uses the XIAO only as a host for a separate compatible vision sensor. That distinction is an important compatibility constraint: the SSCMA library does not make the bundled camera an SSCMA inference target. Camera projects also require correct PSRAM and board-package settings, and the Sense expansion hardware must actually be fitted.
