A series of development boards with versatile microcontrollers and peripherals for development and testing applications.

Seeed Studio XIAO Series Development Board

The XIAO series features a versatile range of microcontrollers, IO interfaces, and peripherals, allowing developers to test and fabricate microcontroller-based applications. With a wide range of board sizes and test cases, the XIAO series allows developers to use pre-integrated platforms for various applications like IoT, 3D printers, mechanical keyboards, trackers, healthcare tools, detection tools, and wearable devices.<h2>A Building Block for More Complex Computing Systems</h2>Seeed Studio XIAO series products provide an excellent option for developers to construct Arduino-compatible system. With a miniature form factor of just 21mm x 17.5mm, the XIAO boards work as powerful computing blocks that can further integrate with external systems. The compact size makes them ideal for space-constrained applications like wearable devices, IoT, and security systems.&nbsp;&nbsp;The boards feature a single-sided SMD design, allowing them to integrate with other XIAO modules easily. Therefore, developers can design entire systems based on an ecosystem of XIAO devices and modules.&nbsp;As a complete computing unit, XIAO series dev boards can reduce the system complexity for testing and implementation of projects.&nbsp;<h2>Comprehensive Development Kit for Seamless Testing and Applications</h2>The Seeed XIAO Series starter kit provides additional peripherals and modules, including an LED pack, expansion boards, sensors, and connection cables.&nbsp;So, developers can create and test applications from an already existing library, just like an Arduino-based system. Moreover, the development environment allows developers to acquire more practical and hands-on experience with the dev board, enabling rapid prototyping, especially for more advanced electronic systems.&nbsp;Additional accessories include Seeed Studio round LCD with a 240 x 240 resolution that connects to the dev board via a USB interface. There is a 2.4 GHz rod antenna for advanced communication and an acrylic case for protection.&nbsp;<h2>Wide Range of Boards for Tailored Applications</h2>The list of processors featuring in Seeed Studio XIAO Dev boards includes:<ul><li>SAMD21</li><li>RP2040</li><li>nRF52840</li><li>ESP32-S3</li><li>ESP32-C3</li></ul>Additional options include Bluetooth, built-in sensors, Wi-Fi, and flash memory. All boards run on Arduino programming languages, while some of them also work with CircuitPython and MicroPython.&nbsp;The Seeed Series development boards can redefine Arduino development, especially for wearable and miniature projects and applications.
