README
README.md561SmartCard-USB - Smart Card Module to USB Bridge Board
スマートカード (ISO/IEC 7816) 互換モジュールを USB Type-C デバイスとして扱うための基板です。
USB-スマートカードブリッジ IC 「SEC1110」を採用しており、CCID 準拠のスマートカードリーダとして動作します。
スマートカード互換モジュールは、USB micro-B または DIP (8 ピン) の 2 種類に対応します。
DIP 形状のものは実物での確認を行っていないため、嵌合・動作しない可能性があります。

備考
- 手実装を前提に SEC1110 (QFP) の Thermal Pad は反対側の面から半田を流し込めるようにしています
- LED はスマートカードアクセス時に点滅します
USB ホストに接続しただけでは点灯・点滅しません - スマートカード互換モジュールのホットプラグには対応していません
USB Type-C ケーブルを抜いてからモジュールを抜き差ししてください

Questions
How big is the 561SmartCard USB PCB?
It measures 30 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 561SmartCard USB use?
33 parts, built around the SEC1110-A5-02, USBLC6-2P6, LTST-C190GKT and USB4105-GF-A. 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 561SmartCard USB KiCad files?
From the yuta2k/561SmartCard-USB repository on GitHub, at the commit this page was made from: the board is kicad/561SmartCard-USB.kicad_pcb and its schematic kicad/561SmartCard-USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 561SmartCard USB 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).
