BB VIEW中国版Beaglebone Black BB-Black AM3359专用扩展板

支持深圳市英蓓特科技有限公司所生产的LCD8000-43T、LCD8000-70T等显示模块。
在BeagleBone Black和BeagleBone上均可使用BB VIEW来扩展LCD接口。
由于设计上同时延伸了BeagleBone Black和BeagleBone的扩展I/O, 所以用户在使用LCD显示功能的同时，不影响对其他IO口的控制与使用。
使用时BB VIEW直接从BeagleBone Black或BeagleBone板获取电源无需额外的电源适配器。
设计上留有定位孔，可以通过加铜柱和螺母使BB VIEW 与BeagleBone Black更可靠地连接。6 BB VIEW的LCD接口引脚定义与Devkit8000、SBC8600等单板机的LCD接口引脚定义相同，硬件上，可完全兼容为上述单板机设计的功能扩展模块。
备注：目前4.3寸、7寸屏已经在BeagleBone Black和BeagleBone上调试可用。VGA8000、LVDS8000 plus后续会更新支持。
