README
README.mdKPPTR-hardware
Welcome to the KPPTR-hardware repository! This repository contains the design files for the hardware components used in the KPPTR project. The design files have been created using KiCad 10.0, a powerful open-source electronics design automation suite.
Project Overview
The design files in this repository correspond to the hardware components that make up the KPPTR project, which enhances the capabilities of DIY amateur rockets and high-altitude balloons. The design files have been crafted using KiCad 10.0, a popular and user-friendly tool for creating electronic schematics and PCB layouts. Both hardware and sofware were developed by PTR member!
Design Files
The repository includes design files for the various hardware components used in the KPPTR project, including:
- Schematics: Detailed electronic schematics that illustrate the connections and components used in the design.
- PCB Layouts: PCB layout designs that define the placement and routing of components on the printed circuit board.
- Libraries: Custom component libraries and footprints used in the project.
Getting Started
To access and work with the design files, follow these steps:
- Clone the repository to your local machine.
- Install KiCad 10.0 if you haven't already.
- Open the KiCad project files (
.profiles) in the appropriate subdirectories to access the schematics and PCB layouts.
Feel free to explore the design files and customize them to suit your specific needs. If you make any improvements or modifications to the hardware designs, consider contributing back to the repository to help the community.

Questions
How big is the PTR mini pcb PCB?
It measures 25 × 74 mm and has 4 copper layers, 1.26 mm thick.
What parts does the PTR mini pcb use?
140 parts, built around the ESP32-S3FN8, GD25Q256EWIGR, MS560702BA03-50 and TPS62142RGT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PTR mini pcb KiCad files?
From the PTR-projects/PTR_mini_hardware repository on GitHub, at the commit this page was made from: the board is PTR_mini_pcb/PTR_mini_pcb.kicad_pcb and its schematic PTR_mini_pcb/IO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PTR mini pcb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
