Satellite code simulation and STM32 implementation of that code
Structure
- Simulation folder includes code that simulates given code that is NOT in STM32.
- STM32 Implementation folder includes code that will be used for the STM32/in the satellite
Organise each sub-folder into subsystem based folders rather than simulation-specific folders for modularity.
STM32 tutorials
The following tutorials might help for STM32 coding. It might be a good idea to spend some time to actually learnt his since STM32 is a complicated yet powerful platform:

Questions
How big is the EPS DESKTOP-1F9J2S9 PCB?
It measures 85 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EPS DESKTOP-1F9J2S9 use?
133 parts, built around the TPS259813ARPWR, BQ25798RQMR, SS24 and M20-6112045. 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 EPS DESKTOP-1F9J2S9 KiCad files?
From the zalak0/Space3 repository on GitHub, at the commit this page was made from: the board is EPS_Ethan's_testing/EPS_ethan/EPS/EPS-DESKTOP-1F9J2S9.kicad_pcb and its schematic EPS_Ethan's_testing/EPS_ethan/EPS/BMS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EPS DESKTOP-1F9J2S9 design in my own project?
Its repository states no licence, so its author keeps all rights: ask zalak0 before reusing the design.
