增加盒子大小,至少保证能放下,

已把板子放大到 90 mm × 90 mm，现在肯定放得下，且布线空间充足。

Layout 改为 90 × 90 mm
仍保持 4 层板
圆角保持 2 mm
板边与 Keep Out 仍为 0.2 mm

现在的状态明显改善：

元件总包围盒约 71.7 × 76.6 mm
新板面积 8100 mm²
元件占板面积约 18.3%
已从“通道拥挤”变成“有比较充裕的布线空间”

下一步最合适的是继续做这两件事之一：

重新整理器件分布，让关键连线更短
继续针对 unroutable / airwires 做第二轮修复

如果你愿意，我就继续帮你压一轮布局，优先把相机、USB、电源、PWM 这几组再拉顺。

继续优化布局

处理布线问题

再加大板子
