Seeed Studio XIAO ESP32S3 leverages dual-core ESP32S3 chip, supporting both Wi-Fi and BLE wireless connectivities, which allows battery charge. It integrates built-in camera sensor, digital microphone. It offers 8MB PSRAM, 8MB FLASH, and external SD card slot. All of these make it suitable for embedded ML, like intelligent voice and vision AI.
NOTE: For enhanced performance, we have upgraded to the OV3660 camera sensor, which operates at lower power consumption and reduced temperature. During this transition, devices with either OV2640 or OV3660 sensors may be shipped.
We are introducing a new more durable packaging for all Seeed Studio XIAO boards (Un-Soldered, Pre-Soldered and Plus). During the transition period, you may receive XIAO boards in either the current or new packaging, while the product quality remains identical. Thanks for your understanding.
- Powerful MCU Board: Incorporate the ESP32S3 32-bit, dual-core, Xtensa processor chip operating up to 240 MHz, mounted multiple development ports, Arduino / MicroPython supported
- Advanced Functionality: Detachable OV3660 camera sensor for 2048*1536 resolution, compatible with OV5640 camera sensor, integrating additional digital microphone
- Great Memory for more Possibilities: Offer 8MB PSRAM and 8MB FLASH, supporting SD card slot for external 32GB FAT memory
- Outstanding RF performance: Support 2.4GHz Wi-Fi and BLE dual wireless communication, support 100m+ remote communication when connected with U.FL antenna
- Thumb-sized Compact Design: 21 x 17.8mm, adopting the classic form factor of XIAO, suitable for space-limited projects like wearable devices
- Pretrained Al model from SenseCraft AI for no-code deployment
Note: XIAO SoM User Manual open-sources all hardware and software materials of XIAO, providing professional product design guidelines to help you accelerate ideas off the ground, streamline product design, providing a seamless experience from module selection to mass production.
