- Remove the Firmware folder? It seems to have been pulled back in from last year.
- Have the project folder (BlackBox) at the top level with Firmware and Hardware underneath. Anything common between projects hardware- or firmware-wise should go in a common/ top-level folder (or some other similar name like core/). Also I'd prefer lowercase with underscores, so black_box/hardware/... etc.

- SPI lines do not use pull-ups, except possibly for MISO. See https://electronics.stackexchange.com/questions/234703/spi-bus-termination-and-pull-up-resistors

- Label the NRST pin on the left side of the BUTTONS section.
- Clean up the left side of the SDCARD_CONS section -- suggest switching the X split locations of MISO1 and MOSI1.
- For components with values (e.g. resistors, capacitors) show the values as well. Right click, properties, markings, additional markings -> Show: Value.

Should NRST not have a pull-up? Or is is just floating/ground? |

Please explain your idea for the accelerometer -- is it on another board? If so, it needs to be another schematic. |

See section 6 Electrical characteristics (particularly 6.1.6, Power Supply Scheme) of the STM32f401re datasheet for how decoupling capacitors should be on the VDD/VSS, VDDA/VSSA, and VREF+/VREF- pins (i.e. values and number of capacitors)
