Designed a CAN logger to log data from the CAN bus to an SD card.

Used the SDMMC protocol on the STM32 to send data to the MCU -- Consulted datasheets and documentation to develop the schematic and connect clk, cmd, dat0... pins to the MCU

Created a schematic and layout for the SD card socket using pull-up resistors to prevent floating pins, and used a TVS diode to protect against electrostatic discharge.

Considered effects like resistance and inductance when planning the layout and adjusted traces accordingly
