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
