# Chubby Hat
A PCB that turns the [Colorlight 5A-75B](https://www.aliexpress.com/item/32728519290.html)
into an easy to use development platform for cheap.
This project ist based on [q3k/chubby75](https://github.com/q3k/chubby75/tree/master/5a-75b).

## Directory Structure
| directory | content |
|------------|----------------------------------------------------------------------|
| source | KiCad project directories |
| production | fabrication files (Gerber, BOM, placement) |
| exports | schematic and layout plots, board 3D model and renderings |
| datasheets | component datasheets |
| assets | board setups, component 3D models, logos |
| scripts | BOM export plugins, miscellaneous helper scripts for file conversion |
| hooks | git hooks, for example for automatic documentation export |
### Version 0.1.0
- USB to JTAG via STM32 or FTDI
- two 3x Pmod ports
### Version 0.2.0
- USB to JTAG via extra dev board or on-board RP2040
- three 2x Pmod ports
## Automation
This repository contains a Makefile that automates PDF and Gerber export, as
well as PCB art pattern creation.
### Requirements
Apart from [KiCad 7](#kicad-version) this requires some additional software.
The Makefile calls a Python script that makes use of [sexptdata](https://pypi.org/project/sexpdata/) to parse KiCad files.
Install [Poetry](https://python-poetry.org/) and run `poetry shell` followed by `poetry install` in the root of this repositoryto set up a virtual environment with the required package(s). To re-enter this environment, simply run `poetry shell` in the root of this repository.
For PDF export you need to install [Poppler](https://poppler.freedesktop.org/).
Gerber export requires [zip](https://infozip.sourceforge.net/).
Pattern creation is implemented with [OpenSCAD](https://openscad.org/).
#### Nix(OS)
If you are using the Nix package manager, you can enter a development environment
with KiCad and all other software by running `nix-shell` in the root of this
repository.
### Export
To export all PDFs and Gerbers, simply run
```shell
make
```
PDFs and Gerbers are exported automatically when you `git commit`, if you have
[Git Hooks](#installing-git-hooks-optional) set up.
### Pattern
To recreate the pattern, first remove the pattern from the board and save it,
then run
```shell
make pattern
```
Add the new pattern graphic to the board.
### Installing Git Hooks (optional)
The [hooks](hooks) directory contains client-side [git hooks](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks).
Currently only the pre-commit hook is used to automatically export plots.
To enable the hooks locally, run the following in the root of the repository.
```shell
git config core.hooksPath ./hooks
```
