README
README.mdCubeSat Solar Array Drive - Cal Poly Senior Project
This repository presents the development and proposed design of a deployable Solar Array Drive Assembly that could be flown on space-bound CubeSat missions. Our project addresses the need for reliable sources of power in spacecraft and other missions beyond the Earth's atmosphere. Our goal is to create a two degree of freedom SADA, including the passive retainment, deployment, and axial rotation of a solar array to track the sun during the CubeSat’s orbit. It will have the ability to be easily adapted and integrated into other CubeSat builds but does not include other subsystems necessary for full satellite. The scope includes three main areas: the design and manufacture of a 90-degree locking hinge that allows multiple solar arrays to deploy from the stored launch state, the controlled axial rotation of the deployed panels, and the electronics necessary to manage these features with the potential for sun tracking algorithms.

Questions
How big is the SADA Board PCB?
It measures 83 × 55 mm and has 4 copper layers, 1.61 mm thick.
What parts does the SADA Board use?
160 parts, built around the STM32L476RGT3, STSPIN220, LM321LVIDBVR-TP and TPS62867RQYR. 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 SADA Board KiCad files?
From the makerCL/JUCI_CubeSat_SADA repository on GitHub, at the commit this page was made from: the board is Electrical/SADA_Board/SADA_Board/SADA_Board.kicad_pcb and its schematic Electrical/Photodiode Breakout/Photodiode_Board/Photodiode_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SADA Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask makerCL before reusing the design.
