Determining Power Placement.

Using Knowledge Base Tool.

Reading docs about How to manually place and move PCB components in Flux, rotate, flip, and lock footprints; centering connectors on board edges; adjusting board outline visibility and using the Objects panel in PCB editor..

Reading docs about How to place and move components in the PCB editor in Flux, including selecting footprints, dragging, snapping/alignment guides, and locking footprints in place..

Organizing Component Placement.

Got it—let’s place the power block in the top‑left. Here’s how to move/rotate parts in Flux:
“This is what the Flux documentation says about positioning: ‘To move a component, left-click on it and drag it to the desired position. For rotating a part, there are two options:
  • Right-click on the part you want to rotate and select "Rotate right" or "Rotate left."
  • To rotate parts quickly, use the open or close square brackets [ ]’ Note: moving or rotating a component creates an Object-Specific Layout Rule you can edit.” Source
What to place in the top-left power zone (in this order from the CAN1 connector inward)
  • At connector power/ground: place J1 (reference), then put F1 in series on Pin‑9 (+12 V) as the first element, with D2 (TVS) very close to the connector’s power/ground for a short, direct return.
  • After the fuse: place D1 (reverse‑polarity protection) on the 12 V path feeding the buck input.
  • Buck cluster: place U3 compactly with its input/output capacitors C1, C3, C4, C5 tight to the appropriate pins per the datasheet; keep the high‑di/dt loop as small as possible.
  • LDO zone: place U4 a bit inboard, with its decoupling C2 right at VOUT/GND, feeding your 3.3 V loads.
  • Keep this entire power area separated from CAN pairs and their return paths; do not route the switcher’s SW/return under the CAN sections.
If you want, I can review placement once you’ve dragged these parts into the top‑left zone.
