QPAD: a didactic game pad

The QPAD is a circuit board developed to teach beginners the basics of soldering, embedded programming and user interfaces. This project was conceived with the following constraints:
- Minimalist: uses as few components as possible
- Flexible: Arduino and MicroPython compatible
- Ready-to-use: examples are provided, and easy to adapt
- Open: all provided code is open-source, and the PCB design is open-hardware
This is an ongoing project, with several variants showcasing different microcontroller families. This project is provided under the MIT License.
