pap-spacing-after-3pt" style="line-height:1.8;">      我认为对于我这种萌新来言，对自己的东西不断修改是十分必要的，如果完成之后弃之不顾，我认为是十分遗憾的，在高中这三年里也画了许多板子仍的也很多，更多是完成部分测试之后就扔一边吃灰了，再之前还是涂鸦智能那次的少见的pcb能打板两次，到最后再看到的时候却也不想再用了，但是涂鸦系列确实是十分有用的，以至于这此画板的时候把涂鸦模块画到了给fpga用的显示屏的背面……只能说对于我这种准大学生画出来的东西应该能用到生活中，这样才能保持对硬件软件的不断完善，要是能产生一定的经济收入那确实可以让重新打板焊接的成本降低不少（直言不讳我就是穷老穷了）。3D外壳还尚未打印，因为有一些东西还想再改改，但是面板已经到手上了还是很合适的给你们看看效果，还是很不错的。<img
