To address these challenges, we present PyCubed-Mini, an open-source 1p PocketQube satellite research platform designed for affordability and user-friendliness. By utilizing readily available components and simple 3D-printed structural elements, the platform significantly reduces the entry barriers, making it accessible to universities, high schools, and individuals eager to engage in space exploration and pursue their research interests. Powered by CircuitPython, a python-based development environment, PyCubed-Mini facilitates contributions from newcomers without limiting the possibilities for advanced research.

This thesis outlines the hardware design of the PyCubed-Mini platform, emphasizing the considerations made to ensure simplicity and cost-effectiveness. Additionally, we have developed open-source testing apparatus that allows comprehensive satellite testing on Earth, including long-range communications, solar charging, power testing, mechanical vibration testing, and day-in-the-life simulations. This testing framework serves as a valuable resource for other satellite programs, reducing development and testing time.

PyCubed-Mini builds upon the legacy of the PyCubed 1U CubeSat avionics, which have flown on three previous missions. The platform incorporates reliable hardware design practices, including novel serial bus protection circuitry and radiation testing data for commercial-off-the-shelf (COTS) components.

The PyCubed-Mini platform represents a significant step towards democratizing space exploration and supporting innovation in the satellite development community. By removing financial barriers and simplifying hardware and software integration, it empowers students and hobbyists to actively contribute to space research and advances in space technology.
