About the Null seet PCB

Null seet is an open source NXP PCB design by MUNAKATA-EPC, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 86.1 mm, with 41 components from 20 distinct parts.

Its main chip is the Teensy4.0, from the NXP family. Other key parts include the module_mpu6050, SeeeduinoXIAO, LF33_TO252 and OpenMV. By type, the board carries 9 connectors, 8 capacitors, 6 ICs, 6 switches, 6 resistors and 5 diodes.

From the project

ヘラクレス2022シーズンのソースコード、設計データを公開しています。詳しくはWikiを参照。

- 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。

Null seet: common questions

What microcontroller does the Null seet use?

The Null seet is built around the Teensy4.0, from the NXP family.

How big is the Null seet PCB?

The Null seet measures 100 × 86.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Null seet?

41 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Null seet design files?

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

Can I use the Null seet 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 Null seet 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.
