Cannot do (to be completed by you)

Ensure all components have footprints by setting each part’s Package property
Add four Ø3.2 mm mounting holes (H1–H4) and connect each pad to GND
Configure a ground plane fill on inner and bottom copper layers
Select and set a standard 4-layer stackup and save in project properties

Success criteria review

✅ All modules (Feather RP2040, MCP25625, ILI9341, buck converter) placed and net-connected
✅ SPI and IRQ lines mapped with separate CS pins
✅ CAN H/G/L terminal block and 120 Ω termination present
✅ Power distribution from 12 V to 5 V and to all devices configured

Next step

Proceed with assigning footprints, defining the board outline and mounting hole placement, configuring the ground plane and layer stackup. Let me know when you’re ready to continue.

Please wire this pinout to the socket headers

jlamflux

@copilot Please wire this pinout to the socket headers

copilot

I'm sorry, but I need more specific information to help you. Could you please specify which pinout you want to wire to which socket headers? For example, you might tell me to connect a specific terminal (such as D5) to a specific pin on a specific socket header (such as Pin_3 on J2).

jlamflux

Can you wire it based on the way its oriented

copilot

I'm sorry for the confusion, but the orientation of the components doesn't help me understand how to connect them. Wiring a circuit involves connecting specific components or pins together based on a schematic or design plan.

Unfortunately, without a netlist or a schematic diagram indicating which pins are to be connected together, I can't generate accurate wiring instructions.

If you have a netlist or schematic for your Feather RP2040 project, please share it so I can assist you further.
