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.

Getting Started with Seeed Studio XIAO ESP32S3 Series

What are the main features of this board and what is its form factor?

It uses the ESP32S3 dual core up to 240 MHz, supports 2.4 GHz WiFi and BLE 5.0, and includes a detachable OV3660 camera sensor, digital microphone, 8 MB PSRAM, 8 MB Flash, and an onboard SD card slot in a thumb sized 21 by 17.8 mm form factor.

Can I use WiFi and BLE at the same time and what is the typical power usage?

Yes, the module supports both WiFi and BLE wireless communication. Power consumption varies by mode, with active operation around 100 to 110 mA and low power sleep modes down to about 2 mA or lower, depending on configuration.

How does the camera sensor work and are there sensor variants I should know about?

The camera is a detachable OV3660 sensor offering 2048 by 1536 resolution and is compatible with OV5640 sensors. During transition, some units may ship with OV2640 or OV3660 depending on inventory.

What packaging options should I expect and are the boards identical across packaging?

Seeed Studio is upgrading packaging for XIAO boards; during the transition you may receive boards in either current or new packaging, but the product quality and functionality are identical.

Is there a pretrained AI model available for no code deployment on this board?

Yes, a pretrained SenseCraft AI model is available for no code deployment to enable AI workloads without extensive coding.
