3、拓展邬接口的形式
网口（100M或者1000M），HMDI（高清视频线) USB口（2.0或者3.0），SD读卡器 充电口（快充口 C口）
一般百兆款usb口不全是3.0，千兆款USB口全是3.0.
4、影响拓展邬价格的因素
接口的数量和种类，接口的品质 数据传输的稳定性 主控芯片（国产 进口）
5、拓展邬与HUB的区别
1）、扩展坞可以扩展出除了USB之外的其他接口，而Hub只能扩展出USB接口。
2）、扩展坞(贵)里面有独立于主板的处理芯片，可以跑自己的程序;Hub(便宜) 只扩展接口。
3）、USB2.0用Hub就够，3.0一般用扩展坞。
6、我们拓展邬的定制方式

7、拓展坞的接口情况
HDMI （高清视频）
VGA (视频)
3.5圆口 耳机口 耳机线
读卡器 SD卡 TF卡
USB口 插U盘 插口令牌 其他USB设备
网口 接网线
type-c 口 传输数据或者充电
8、关于拓展坞的发热以及稳定性
拓展坞在高速工作的过程中会涉及到芯片对于数据的高速处理，因此会产生一定的热量，这点同U盘在使用过程中产生一定的热量的原理是相同的，如果是产品到了发烫的情况，效果上就完全不同了。
9、关于拓展坞的稳定性
我们这边用的处理芯片和很大牌产品的芯片是同一个等级的，具有良好的稳定性和数据处理速度，这点您完全可以放心的，到现在为止我们还没有客户反馈过这方面的问题
10、关于拓展坞带网口的比较贵的原因
现在网卡都很贵，一个百兆网卡正常十几二十块，千兆网卡差不多30元
11、客户要USB接口，但是又需要HMDI接口
如果是拓展坞需要HMDI接口的话 就必须要有C口，usb口连接电脑不支持高清视频播放，另外拓展坞主要是适用于笔记本，有些功能诸如HMDI功能在台式机并不适用，因为台式机主板已经涵盖了这些接口功能。
扩展坞（Docking station），又称端口复制器（Port Replicator），是专为笔记本电脑设计的一种外置设备。通过复制甚至扩展笔记型计算机的端口，可使笔记本电脑与多个配件或外置设备（如电源适配器、网线、鼠标、外置键盘、打印机及外置显示器）方便的一站式连接。
拓展坞的好处
1、提升工作效率 对于上班族来讲 上班插上，下班拔掉，简单方便
2、对于手机 ipad等可以连接网线，提升网速的稳定性
3、投屏转接
4、供电

影响拓展坞价格的要素
1、HUB 分线器 29---55 只是单纯端口复制的功能，常见的有USB 一拖三 一拖四
2、带视频转接线功能 HDMI、DVI和VGA接口 70--150
3、PD快充口 充电口 TYPE-C口 70--150
4、网口 千兆网口 百兆网口 70--150
5、USB口的数量和传输速度
6、以上接口的稳定性
7、其他辅助功能，诸如无线充功能，支架功能等。
