ADCS MCU - MicroSD card long-term storage design

[Aidan-Sheedy]

Motivation/Description ⛰️

The MCU needs a way of storing long-term data, such as sensor telemetry, calibration data, etc. This has been designed for OBC V1, and may be able to be adapted to the ADCS MCU.

Next Steps 🚶

• [ ] Review long-term storage on OBC V1. It is a MicroSD implementation. Key features to look at are:
  • Size of storage available
  • Complexity of design
  • Storage medium used
  • Availability and cost of components
  • Future upgrades recommended by OBC
• [ ] Document what parts of the OBC V1 design are transferable to the ADCS MCU and what parts need redesigning. This should be done in the ADCS MCU documentation.
  • [ ] All transferable design features should be documented as the current implementation in the documentation
  • [ ] All non-transferable features or changes required should, along with being documented, have a ticket craeted to address the shortcomings.
• [ ] Create a circuit diagram for the long-term storage. This should be stored in the ADCS Teams and the ADCS GitHub.

Supporting Material and Resources 📖

• OBC V1 Documentation
• OBC STM32 PCB Design
• ADCS MCU Documentation

Definition of Done 💯

This task is done when:

• The OBC V1 long-term storage design has been transferred to the ADCS MCU
  • All transferable design features have documented
  • Missing/non-transferable features have a new ticket
• A circuit diagram of the long-term storage has been created in the GitHub and the ADCS Teams channel. This is a working document, and is not expected to be complete.

We will not be using an SD card in the ADCS MCU design, as we only need one storage medium.
