README.mdCircleLED UNIT
3.5mm角サイズのフルカラーLED(WS2812B-Mini)を36個、円形に配置した直径35mmの円形ディスプレイです。Grove端子から給電・制御することができます。4箇所に固定用の穴(φ2mm)があり（中心から22mmの位置）、またこの穴を含む出っ張りの部分はカットすることもできます。
M5StackのHEXボードやLEDテープと同様に使用することができます。（LED数は「36個」に設定してください）
使い方（接続方法）
"IN"と表記されたGroveコネクタのいずれかに、マイコン(M5Stack等)からのGroveケーブルを接続します。さらに数珠つなぎで別のLEDテープや本ユニットを接続する場合は、"OUT"と表記されたGroveポートを使用してください。

Questions
How big is the CircleLED Unit PCB?
It measures 46 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CircleLED Unit use?
62 parts, built around the WS2812B-MINI-X2. 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 CircleLED Unit KiCad files?
From the akita11/CircleLED_Unit repository on GitHub, at the commit this page was made from: the board is CircleLED_Unit.kicad_pcb and its schematic CircleLED_Unit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CircleLED Unit 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).
