About the Main Board

Main Board is an open source NXP PCB design by MUNAKATA-EPC, published on GitHub under the MIT license. It is a 2-layer board measuring 120 × 113.1 mm, with 58 components from 23 distinct parts.

Its main chip is the Teensy4.0, from the NXP family. Other key parts include the Stamp_Pico, SeeeduinoXIAO, OpenMV, LF33_TO252 and module_mpu6050. By type, the board carries 16 connectors, 12 capacitors, 8 ICs, 8 switches, 8 resistors and 5 diodes.

- 大きな変更をするときはブランチを絶対に別途作成しましょう - 小さな変更(スペルミスやコメント修正程度)ならどんどんmainブランチに突っ込んでもまあ構わないでしょう - 余裕があったら変更した内容をコメントしてくれると助かります

- 各プロジェクトフォルダの命名規則は「hogehoge(プロジェクト名)-teensy40(開発環境名)」となっていますが、一部試験用に作ったものに関しては、この命名規則が守られておりません...ごめんなさい。 - プロジェクトフォルダ内の「src」フォルダ内にmain.cpp(一部プロジェクトは名称が異なります)、「lib」フォルダ内に各種ライブラリ、「include」フォルダ内にサブプログラムが入っています。 - 一部PlatformIOからダウンロードしているライブラリが含まれているため、基本は「VSCode + PlatformIO」の組み合わせでご覧ください。

Main Board: common questions

What microcontroller does the Main Board use?

The Main Board is built around the Teensy4.0, from the NXP family.

How big is the Main Board?

The Main Board measures 120 × 113.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main Board?

58 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main Board design files?

From the MUNAKATA-EPC/Hercules_2022 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Main Board design in my own project?

Yes, under the terms of its MIT license, which MUNAKATA-EPC chose for the repository.

Can I test firmware for the Main Board without the hardware?

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