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
firmware:
ardu/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
