XIAO SoM User Manual opensource hardware and software resources of XIAO, providing professional product design guidelines to help you accelerate your ideas off the ground. This User Manual can provide everything needed from module selection to the final manufacturing.
XIAO boards have enabled innovators and creators to bring their ideas to life and demenstrated the huge potential of scaling up by being utilized in various vertical applications. In 2023, we will be taking the next step in our journey by offering XIAO Series as System-on-Modules. With this new offering, Seeed is expected to be able to provide a complete service with even greater flexibility and customization options, empowering you to tailor XIAO-based solutions according to specific needs.
In addition to a detailed wiki for each product, we also have courses for Arduino beginners based on the Seeed Studio XIAO series of products, which will take you through a step-by-step project to learn programming and create fun work.
Why Seeed Studio XIAO series matters to Arduino learners?
Early Arduino development boards, such as the 8-bit, 16 MHz Arduino Uno, were very large and limited in terms of capacity and performance. Now the Seeed Studio XIAO series products, the size of a thumb cover, offers more powerful performance in a much smaller size, providing more possibilities for Arduino creation.
Through hands-on practice and a project-based approach, this course will take you to step by step to learn how to use Seeed Studio XIAO series products to learn Arduino from scratch, from simple lighting of LED lights to building complex Arduino wearable and miniaturized projects.
In addition, you will learn how to quickly create a usable electronic product prototype from the course.
This course does not require Arduino programming or electronics knowledge.
The course will take you to step by step to help you understand and learn necessary knowledge, and quickly practice in each project.
Since the release of our first Seeed Studio XIAO, the community has been continuously contributing projects, ranging from simple beginner-level projects, such as a desktop weather station, to advanced projects, such as a customized keyboard, and to product-level projects, such as a master control board for a 3D printer.So, how can Seeed Studio XIAO Series products spark your creativity?
You are welcome to share your projects made with XIAO series products with Seeed Studio. We will carefully select excellent projects and regularly update the promotion. For details, please refer to this page.
