Seeed Studio XIAO INTRODUCION
Seeed Studio XIAO Series consists of 7 versions to satisfy the diverse needs of makers, product designers, and educators. If you're a maker, you can take advantage of its rich community resources to get inspiration and knowledge for your own projects. The XIAO Series offers educators a comprehensive gettingstarted course and detailed wikis to quickly learn how to use XIAO for their projects. If you're a product designer, XIAO SoM User Manual covers everything from Module Selection to Mass Production.
XIAO is a combination of compactness, capability, and user-friendly design. The whole XIAO Series features compact design withall SMD components are placed on the same side of the board, so designers can easily integrate XIAO into their own boards for rapid mass production.
