Meishi PCB using CH552

基板の表や裏の空いているところに、自分の名前などをシルクで入れれば、オリジナル基板のできあがり。 あとは製造発注して、名刺代わりに配りましょう。

基板製造時に部品実装(PCBA)もいっしょに注文すれば、ArduinoIDEでプログラムを書けるマイコンボードとしても使えます。もちろん自分で部品をはんだ付けしてもOK。 （CH552duinoと同じ構成ですので、これの使い方を参照してください。使い方を含めた解説書もあります。）

- 基板の一部にあるUSB端子を直接PCへ（USB端子の周りの板を切り取って使います。（※板厚2.0mm。それより薄い場合は厚紙などをはさむ） - 基板上部にあるUSB Type-C端子にUSB Type-Cケーブルで接続（※板厚0.6mm） - 基板上にUSB Type-Cコネクタを実装し、USB Type-Cケーブルで接続

MeishinoCH552 sample: common questions

What microcontroller does the MeishinoCH552 sample use?

The MeishinoCH552 sample is built around the CH552T, from the WCH CH32/CH55x family.

How big is the MeishinoCH552 sample PCB?

The MeishinoCH552 sample measures 91 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MeishinoCH552 sample?

19 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MeishinoCH552 sample design files?

From the akita11/MeishinoCH552 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MeishinoCH552 sample design in my own project?

Yes, under the terms of its MIT license, which akita11 chose for the repository.

Can I test firmware for the MeishinoCH552 sample without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug WCH CH32/CH55x firmware against it before you order a PCB.
