Preface：为何要写/Why to Compose
近日遇到了一位做DIY刷机线的商家，他卖的线正好有磁吸，对我这种依赖刷机稳定性的人来说正好需要。然而交流过程中可能出现了理解偏差，导致对方发的线序是反的。
所以我写了这篇文章。
Recently I found a shop which sells custom data cables with magnet, which was capable for me who needs transfer stability. However, I found that we might have some understanding bias, which makes the cable’s line sequence upside down.
That’s why I composed this article.
Notice/注意
本文为中英双文，主要辅助海内外DIY线的商家，避免理解偏差导致的扯皮。
如果可以，请尽量阅读中文版本，并尽量对本文的英文部分做意见提出与修正。感谢！
This article has 2 languages provided: Chinese & English, and it intends to help shops who makes DIY cables for TicWatch Pro, Pro 3, Pro 3 Ultra/Pro X, and more, to avoid possible quibbles as much as possible.
If possible, please stick to Chinese version. Thanks!
省流/TLDR
TicWatch Pro、Pro 2020、Pro 2021、Pro 3、Pro 3 Ultra、Pro X、E3共享同一线序，甚至同一间距。E3和E只是数据脚对调。
它们的线序整理起来如下：双按钮向前，从左到右的四个触点分别对应：黑（GND）、白（D-）、绿（D+）、红（VCC），为USB 2.0协议。
TicWatch Pro, Pro 2020, Pro 2021, Pro 3, Pro 3 Ultra, Pro X, E3 share the same line sequence, and even pins spacing. TicWatch E & E3’s difference is only that data points swap.
Their line sequence is defined as following: make double buttons front, contact points from left to right corresponds to: black (GND), white (D-), green (D+), and red (VCC), which should be USB 2.0.
TicWatch Pro 3 & TicWatch Pro 3 Ultra / Pro X
TicWatch Pro 3，3 Ultra和X共享同一个机型代号，Rubyfish（non-LTE）或Rover（LTE）。此外，中国的TicWatch Pro X为海外版的TicWatch Pro 3 Ultra。
至于它们硬件是如何区分的，很简单，根本不区分，软件上直接读oem.prop开启对应功能。
这同时意味着它们共享线序。
据XDA、酷安，它们的线序整理起来如下：双按钮向前，从左到右的四个触点分别对应：黑（GND）、白（D-）、绿（D+）、红（VCC），为USB 2.0协议。
TicWatch Pro 3, 3 Ultra and X share the same product code, Rubyfish (non-LTE) or Rover (LTE). Moreover, Chinese version of TicWatch Pro X is overseas version of TicWatch Pro 3 Ultra.
About how to distinguish, that’s far more simple, that Mobvoi does NOT do that, and at the software level the system reads oem.prop to enable certain functions.
That also means they share the same line sequence.
According to XDA and Coolapk, their line sequence is defined as following: make double buttons front, contact points from left to right corresponds to: black (GND), white (D-), green (D+), and red (VCC), which should be USB 2.0.

TicWatch E3 & TicWatch E
目前需要注意，据酷安，TicWatch E和E3的线序不同。然而，让我很意外的是，TicWatch E3的线序竟然和Pro 3是相同的！
至于E和E3的线序有什么区别，很简单，数据脚（D+和D-）对调了。
然而TicWatch E的线序发表出来实际没啥意义，原因是TicWatch E的原装数据线具有完整的4个针脚。
As a notice, according to Coolapk, TicWatch E has a different sequence towards to TicWatch E3. However, to my surprise, TicWatch E3’s sequence is same as Pro 3’s!
About the difference between E and E3, data points’ (D+ and D-) sequence swapped.
However it’s actually meaningless to publish TicWatch E’s, as it has full points in its stock cable.

TicWatch Pro
一个很生草的消息：据Reddit，TicWatch Pro与TicWatch Pro 3的充电板子完全通用，甚至只需要再套个壳子就可以给Pro 3用了。
A memeful tip: according to Reddit, TicWatch Pro’s charging board is completely compatible with TicWatch Pro 3. You even only need a shell to make it “useful” for TicWatch Pro 3。
