"""生成 KiCad 符号库 kicad/lib/PhoneRail.kicad_sym。
|
||||
|

来源：EasyEDA 工程包里的 .esym（页面源码里没有符号图形，必须用工程包）。
|
||||
|
||||
坐标：EasyEDA 符号和 KiCad .kicad_sym **都是 Y 向上**，所以图形不翻 Y，只做单位换算
|
||||
（1 单位 = 0.01 inch = 0.254 mm）。引脚 (x,y) 两边都是「连接点」，rotation 两边都是
|
||||
「从连接点指向本体」的方向，可以直接映射 —— 已用 LMR51430YDDCR 实测核对。
|
||||
|
||||
产出两类符号：
|
||||
· 68 个元件符号（part 引用的）
|
||||
· 4 个电源符号（netflag 的 GND / +12V / +3V3 / +3V3_HUB），带 (power) 标记，
|
||||
KiCad 靠它做电源网络的全局连接
