About the GS PCB

GS is an open source ESP32 PCB design by wasa-rockoon, published on GitHub under the MIT license. It is a 2-layer board measuring 60 × 60 mm, with 88 components from 44 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the TPS3820, SN65HVD230, NEO-M9N-00B, MCP73871-1CC and TPS2116DRL. By type, the board carries 27 resistors, 23 capacitors, 9 ICs, 6 connectors, 6 diodes and 4 LEDs.

From the project

WASAロケットプロジェクト 共通電装基盤

WOBCは，WASAロケットプロジェクトにおける電装関連の共通基盤を確立することを目的としたプロジェクトである． 開発した回路や基板の設計情報，プログラムといった資産を再利用しやすい形で整備することで， 開発スピードを向上させるとともに引き継ぎや教育を効率的に行えるようにする．

コンポーネントを一枚の基板上に配置した，物理的な単位．例：地上局モジュール，通信モジュール

モジュールには必ずマイコンが含まれ，コンポーネントを制御する． ユニットを構成するモジュール間はバスで接続される．

ユニットを構成する，意味のある一つの機能単位．例：電源管理，姿勢決定，モーター駆動

ユニットやコンポーネント間でやり取りするデータの形式． 詳しくはWCPPを参照．

モジュールやコンポーネントは，全てこのリポジトリに格納する（Monorepoスタイル）．

GS: common questions

What microcontroller does the GS use?

The GS is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the GS PCB?

The GS measures 60 × 60 mm, has 2 copper layers and is 1 mm thick.

How many components are on the GS?

88 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the GS design files?

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

Can I use the GS design in my own project?

Yes, under the terms of its MIT license, which wasa-rockoon chose for the repository.

Can I test firmware for the GS without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
