Alexey Zayanchukovsky / canfd-to-usb - History

HW: PCB small-fix

Added thermal reliefs to Solder-Jumpers
Slightly moved J2 and J4 to make clearence for mounting holes
Moved R10 for the same reason

HW: Footprints and components layout

Added footprints for all components and created a new one for USB
connector. Started the components layout with positioning of all
components on the PCB before laying out the traces.

HW: Added footprints for all components

Created the footprint for USB-Type-C connector
Added footprints for the rest of the components on the PCB.
Started the mock-up placement of components on the board

HW: Schematic fixes, PCB outline fixes

1. PCB outline is now a rectangle, arduino pins are removed
2. 22u tantalum cap added on 5V rail
3. USB termination resistors are removed as they are implemented
in MCU's PHY
4. Buttons are stronger pulled-up with 10k resistors instead of
100k like on other stm boards, 100 Ohm resistors added in series
with debouncing caps
5.Placeholder components remowed
6.Shielding through 220k resistor with 10n cap
7.ESD protection connection fixed
8.USB Type-C instead of Mini-B
9. Replaced standby mode jumpers with solder-jumpers for choosing
between always normal mode or controlled through MCU. Current-limiting
resistors added on standby lines.

HW: Schematic update - BH connectors

1. Added BH connectors for ribbon cable connection to CAN-bus.
2. Hopefuly fixed the kicad library linking problem.
Schematic is ready to be reviewed before
laying out the PCB.

HW: Schematic edit - buttons and LEDs

Added buttons and LEDs to schematic, minor fixes in
existing components. Assigned most components with
their respective footprints.
