flux

Work done
  • Project description updated to include Feather RP2040, MCP25625 CAN, ILI9341 TFT, 12 V→5 V buck, CAN H/G/L terminal block (#FeatherRP2040 #CAN #TFT #BuckConverter)
  • System architecture diagram added to project property
  • Major ICs placed:
    • U1 MCP25625-E/SS
    • U2 ILI9341
    • U3 TPS63070 Buck Converter
  • Power connector: J3 TB003-500-P02BE (12 V in)
  • Buck support:
    • L4 4.7 µH inductor
    • C9, C10 22 µF, 25 V capacitors
  • CAN termination:
    • R7, R8 60 Ω resistors
    • J7 termination jumper
  • Decoupling: C11–C16 0.1 µF, 10 V each
  • Pull-ups: R11, R12
  • Connectors:
    • J4 TFT header
    • J6 TB003-500-P03BE CAN H/G/L
  • Nets wired: SPI (SCK/MOSI/MISO), CS_CAN, CS_TFT, DC, RST, IRQ, 12 V→buck VIN, buck VOUT→VBUS/VIN1/LITE1, GND, CANH/CANL
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

@copilot Please wire this pinout to the socket headers

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).

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.

    Properties

    J1 Pin_11 (labeled D6 on Feather RP2040) → Net INT → U1:~INT

    Not used / not populated in this revision

    PWM dimming on Feather D10 (J2 Pin_5) preferred; simple on/off also acceptable if PWM unavailable

    H–G–L (J6: P1=CANH, P2=GND, P3=CANL)

    J1 Pin_4 (labeled D9 on Feather RP2040) → Net CS_TFT → U2:CS2

    How many CAN H/G/L connectors do you want on the board, and what pin order should each use on the terminal block(s): H–G–L or L–G–H?
