Description: 此图为我自已研究了扬创公司的开发板后，
参考他们的开发板主板图画的电路图和PCB板图。
注意，扬创公司的开发板是主板加核心板的构架。
因此，我的图也是基于此构架的。
我的图是主板图（不含核心板图）。
电路图和PCB板图是PROTEL99格式的。
功能上除了没有摄像头接口电路外，其余功能全有，
并增加了一全双工485口，一半双工485口，
一4*8的矩阵键盘接口，液晶屏LED背光驱动电路，
板子需配合扬创公司的S3C2440核心板工作。
画得不是太好。但所有功能经验证全部正常，
我用的屏是三星LTP700WV-F01，自带触摸屏的型号，
另，限于扬创公司的核心板功能，
此板支持液晶屏只能支持到65K色。
有感于网上共享PCB板图的较少，在此与大家共享。
如有疑问，可以和我联系：nanjinrat@sohu.com-err
