詳細說明
一直到現在為止，我還是無法適應軌跡球...
我個人沒有辦法去適應軌跡球的移動模式，更不用說要用什麼方式去操作它，因此在我將探索者1號設計出來的當下，我就知道還有一個將遊戲搖桿（Joystick）加進鍵盤內的構想在，也確實也有不少前輩設計出來，比如Dactyl Manuform Skeleton Edition的完整STL模型中，就有搖桿的存在。但礙於當時的我沒有足夠地了解3D建模及QMK韌體，一直到現在才有能力將這個很久以前就一直深埋在內心的夢想付諸實行。
它叫做Prime52，很簡單直接地說，它就是搭載Joy-con搖桿、EC-11旋轉編碼器及滑鼠滾輪的一把矮軸鍵盤，支援Choc v1、v2熱插拔。

組裝鍵盤前務必先將韌體刷入MCU中，便測試及安裝方面會比較輕鬆容易：點我進入組裝說明
現階段版本問題點
 |  |
|---|---|
 |  |
- 滑鼠滾輪安裝上的困難，未來改進有無按鍵雙支援。
- 滑鼠編碼器的脈衝問題（暫時無法解決）。
- MCU的侷限性，未來可以支援更多類型的MCU，往大眾常使用的為主。
- 電路板的走線問題，也是無法支援更多MCU的主因。
- Slave端搖桿電位漂移、LED燈訊號有時而不穩定，有可能會開發新的鍵盤直接改掉這些問題。
- 看似對稱，但無法設計成對稱（Joy-con搖桿的主因）。
這是實際到手的v1版本在組裝上遇到的問題，v2版本的PCB會解決這個問題，並且會開發MX及GLP的版本出來。

Questions
How big is the Prime52 PCB?
It measures 348.6 × 107.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prime52 use?
176 parts, built around the WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Prime52 KiCad files?
From the DreaM117er/Prime52 repository on GitHub, at the commit this page was made from: the board is file/pcb/Prime52.kicad_pcb and its schematic file/pcb/Prime52.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prime52 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
