What

• add in CAN support

  • four pin JST for drone

    • the 100mil things on the side didnt work out too well

    • we had issues with pads ripping off on first rev

  • use common CAN circuit referenced in ESC CAN Adapter with stm

• change to support peggy and fixed wing mechanical packaging

  • need to validate the motor mount strategy works. Alternatively 30x30mm might be nice to mount on bottom of center frame?

• fix all comments in schematic

  • https://warg.365.altium.com/designs/0607B0A9-D0B3-4808-A201-214B5C1EDFB1#design

• firmware:

  • ardu support /pixhawk controlled for thsi ensured.

  • controllable from controller on ground through pixhawk or automated scripts on the ground or droneside from rpi or something.

• all components on one side of the pcba?

  • easier to paste them all in one go.

  • easier to inspect and mount

• mounting pattern

  • sticking with 40x40 M4 for peggy motors seems optimal

  • could go with 30x30mm/30.5x30.5mm M3 so we can mount to other parts of frame more commonly

Concerns

• must use low datarate and both CAN buses to avoid sublength becoming an issue

  • toggleable termination

Why

• we are able to control the pattern in firmware without reflashing the boards

• Simple 1:1 harness can be used

  • harness was a massive problem on first rev

  • looked ugly

• Would be cool if they all sync up and change colors to represent flight modes

Who

• Daniel Puratich Drawing the schematic

• Parker Lawrence-Valeriani ?

When

• unknown
