The mass storage on our CubeSat's OBC (on-board computer) is provided in the form of an SD card. These cards come with an integrated memory controller which manages functions like wear leveling, and provides a simplified interface. In order to implement experimental flash translation layers and file systems, we require more direct control over the underlying flash memory.

In this thesis, your task is to design a flash-based mass storage module which our OBC can interface with. For this, you will compare (QSPI) flash chips based on tolerance of space conditions, capacity, and speed. Based on the chosen chip, you will then design the PCB, and evaluate functionality. For this, you will also write a basic driver for flash interaction.
