Important Notes
- This listing is for the XIAO ESP32-S3, not the XIAO ESP32-C3 or XIAO ESP32-S3 Sense.
- The standard XIAO ESP32-S3 and the Sense version differ in hardware features; confirm the exact model before listing.
- GPIO pins use 3.3V logic and are not 5V tolerant.
- USB cable, headers, and other accessories may not be included.
- Memory configuration and available pin functions should be verified against the exact board version.
