<h3>SparkFun Microcontrollers</h3> This library contains microcontrollers. <br> <br> We've spent an enormous amount of time creating and checking these footprints and parts, but it is <b> the end user's responsibility</b> to ensure correctness and suitablity for a given componet or application. <br> <br>If you enjoy using this library, please buy one of our products at <a href=" www.sparkfun.com">SparkFun.com</a>. <br> <br> <b>Licensing:</b> Creative Commons ShareAlike 4.0 International - https://creativecommons.org/licenses/by-sa/4.0/ <br> <br> You are welcome to use this library for commercial purposes. For attribution, we ask that when you begin to sell your device using our footprint, you email us with a link to the product being sold. We want bragging rights that we helped (in a very small part) to create your 8th world wonder. We would like the opportunity to feature your device on our homepage. >NAME >VALUE >NAME >VALUE >NAME >VALUE >NAME >VALUE >NAME >VALUE >NAME >VALUE D17/RX LED D15 D16 D14 D8 D9#/A8 D10# D11# D5# D13# D3# D2 D0 D1 D4/A6 TX LED D12/A10 D6#/A7 D7 A0 A1 A2 A3 A4 A5 <h3>Atmel MCU, 32KByte</h3> <p>Atmel 44-pin 8-bit Microcontroller with 32KBytes of ISP Flash and USB Controller</p> <p><a href="http://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/ATMega32U4.pdf">Datasheet</a></p> <h4>SparkFun Products</h4> <ul> <li><a href="https://www.sparkfun.com/products/12049">LilyPad Arduino USB - ATmega32U4 Board</a> (DEV-12049)</li> <li><a href="https://www.sparkfun.com/products/12640">Pro Micro - 5V/16MHz</a> (DEV-12640)</li> <li><a href="https://www.sparkfun.com/products/12587">Pro Micro - 3.3V/8MHz</a> (DEV-12587)</li> <li><a href="https://www.sparkfun.com/products/11520">Fio v3 - ATmega32U4</a> (DEV-11520)</li> <li><a href="https://www.sparkfun.com/products/13614">Qduino Mini</a> (DEV-13614)</li> <li><a href="https://www.sparkfun.com/products/11511">Makey Makey - Standard Kit</a> (WIG-11511)</li> <li><a href="https://www.sparkfun.com/products/11519">Makey Makey Deluxe Kit</a> (WIG-11519)</li> </ul> Since Version 8.2, EAGLE supports online libraries. The ids of those online libraries will not be understood (or retained) with this version. Since Version 8.3, EAGLE supports URNs for individual library assets (packages, symbols, and devices). The URNs of those assets will not be understood (or retained) with this version. Since Version 8.3, EAGLE supports the association of 3D packages with devices in libraries, schematics, and board files. Those 3D packages will not be understood (or retained) with this version.
