Libraries are created according to the datasheet of the component that you wish to use. There are&nbsp;the schematic symbols, PCB footprints, and the description of the component. Creating a perfect library will no doubt be a laborious process, especially for a large number of pins or for components with more complicated pinouts. If you do not spend at least 3 days creating a package for a specialized part with more than 100 pins, you are probably going to feel uneasy about using it.<\/p>\n<p>Fortunately, there are already many online resources contributed by many experienced engineers, who are well-versed in various CAD tools. Together with engineers from TI, ADI, Microchip, Maxim, and TE, they have created files for mainstream CAD tools, and they share them on their own websites and the websites of its original creator. As a result, they have reduced the workload of the PCB design engineers. This means that you do not have to build your own component libraries.<\/p>\n<p>Some well-known websites have been compiled, regarding two pieces of PCB design software &#8211; KiCad and Eagle. Now, let\u2019s look at the two libraries and their distributors.<\/p>\n<h2>1. KiCad<\/h2>\n<p>KiCad\u2019s official libraries are available for download on their They include schematic symbols, PCB footprints, and comes complete with 3D modeling data to complement their&nbsp;own 3DViewer tool, which enables you to inspect your design more in detail with an interactive 3D view.<\/p>\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/blog.seeedstudio.com\/wp-content\/uploads\/2019\/01\/KiCad-blog-pic.png\" alt=\"\" class=\"wp-image-20131\" width=\"340\" height=\"332\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/KiCad-blog-pic.png 848w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/KiCad-blog-pic-300x294.png 300w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/KiCad-blog-pic-768x753.png 768w\" sizes=\"(max-width: 340px) 100vw, 340px\" \/><\/figure><\/div>\n\n\n<h2>2. DigiKey<\/h2>\n<p>DigiKey, the renowned component distributor has cooperated with KiCad to sell major&nbsp;components from KiCad\u2019s library on its website. And of course, when you use KiCad to generate a BOM list, it will direct you to DigiKey\u2019s website, implying that you should purchase the materials from DigiKey.<\/p>\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/blog.seeedstudio.com\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic-1030x1016.png\" alt=\"\" class=\"wp-image-20133\" width=\"357\" height=\"352\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic-1030x1016.png 1030w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic-80x80.png 80w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic-300x296.png 300w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic-768x757.png 768w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2019\/01\/DigiKey-blog-pic.png 1073w\" sizes=\"(max-width: 357px) 100vw, 357px\" \/><\/figure><\/div>\n\n\n<h2>3. Ultra Librarian<\/h2>\n<p>Ultra&nbsp;Librarian can not only search for technical specifications and purchase channels of all the components, but also provides&nbsp;libraries&nbsp;for&nbsp;major components. Also, it supports not only KiCad but many other CAD tools as well.
