Requested Changes by Austin

Both boards:

  1. Remove resistors on IMU (the two resistors are only put there is we are trying to configure the board into I2C mode, but we are using the default SPI mode for which the resistors should not be connected)

  2. Easy way to tie GPIO 1 to GPIO 8 and a way to tie GPIO1 to GPIO9 with pin header. This is useful for lighthouse localization.

  3. There is a discrepancy between the bond diagram for ALWAYSON_LDO_OUT for https://github.com/PisterLab/scum-dev-board/blob/quikpak_ll/qfn_info/bigBoard_bond_diagram.pdf and https://github.com/PisterLab/scum-dev-board/blob/master/scum3c_devboard_large/Images/scum3C%20Large%20Board%20bond%20diagram.png . Both boards have this discrepancy and should be modified to match the first link.

  4. Add the missing SCuM pins to schematic (mark as no connections) just for bookkeeping

  5. Currently SDO pin on IMU is connected to GPIO12 and SDI pin on IMU is connected to GPIO13. It would be nice to have SDO pin on IMU connected to GPIO13 instead and SDI pin of IMU connected to GPIO12. This is to match the hardware configuration with the code Brian wrote before to maintain as much consistency between boards as possible so code can be reused across all of them.

  6. Request from DB: “it would be nice to have plated vias on as many of the SCuM pins as possible so we can fully wirebond and then thread a 30 AWG wire in if we need to splice something on“
