Teensy CAN Gateway Design
Thought for 2 mins 23 sec
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.
