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 6.0, 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 6.0, 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 6.0 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 Kp ptr PCB?
It measures 31 × 100 mm and has 4 copper layers, 1.26 mm thick.
What parts does the Kp ptr use?
208 parts, built around the E22-400M22S, ESP32-S3, MMC5983MA and MS560702BA03-50. 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 Kp ptr KiCad files?
From the PTR-projects/PTR_mega_hardware repository on GitHub, at the commit this page was made from: the board is kp-ptr/kp-ptr.kicad_pcb and its schematic kp-ptr/IO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kp ptr 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).
