README
README.mdCH552duino
WCH(南京沁恒微电子股份有限公司)の8ビットマイコンCH552を使った、Arduino UNO型のマイコンボードです。 主な特徴は以下のとおりです。
- Arduino UNO型
- ArduinoIDEなどでプログラム開発が可能
- USBペリフェラル（キーボードやUSBメモリなど）として動作可能
- USB Type-Cコネクタ
またArduinoUNOとは、以下のような違いがあります。
- 一部ピンの機能が異なる
- 一部未接続のソケット端子がある
- +3.3V出力の電流供給能力は100mA程度（CH552内蔵レギュレータの性能）
- リセット(RST)は正論理で、"1"でリセット
- +5V端子に、外部電源から+5Vを供給可能（内部にレギュレータはないので、+5Vを超える電圧は不可）
基板上の"LED"（オレンジ）はP1.7で駆動できます。

Questions
How big is the CH552duino PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH552duino use?
24 parts. 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 CH552duino KiCad files?
From the akita11/CH552duino repository on GitHub, at the commit this page was made from: the board is CH552duino.kicad_pcb and its schematic CH552duino.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH552duino 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).
