Seeed Studio XIAO ESP32S3 Sense (Camera + Mic)

The Sense edition adds a clip-on expansion board to the XIAO ESP32S3: a detachable camera, a digital PDM microphone and a microSD card slot. Together with 8 MB PSRAM and the S3's AI-friendly vector instructions, it can stream video over Wi-Fi, recognise faces or objects with Edge Impulse / TensorFlow Lite models, detect keywords and record to SD — all from a board smaller than a coin. Remove the expansion board and you have a regular XIAO ESP32S3.
