Setting up the plan.

I will create a new Module component “MCP2515 CAN Bus Module” with a custom symbol and footprint per your specs.

Symbol: 9 pins (INT, SCK, SI, SO, CS, GND, VCC, CAN_H, CAN_L) with correct types.
Footprint: 40 x 28 mm, 4x Ø3.2 mm holes spaced 35 x 23 mm, 7-pin 2.54 mm header (left), 2-pin 5.08 mm screw terminal (right).
Map pins, set properties, add to project, and place an instance.

Please confirm:

Header top-to-bottom order: INT, SCK, SI, SO, CS, GND, VCC?
Screw terminal left-to-right: CAN_H, CAN_L?
Preferred footprint origin: board center or top-left corner?

Started implementing a plan

#Goal

- Create a new module component named "MCP2515 CAN Bus Module" with a custom schematic symbol and footprint based on exact user specifications, and add it to the ESP32-DEVKIT-V1 project for integration with the ESP32 host.

#Implementation plan

1. Create a custom schematic symbol for the MCP2515 CAN Bus Module

1. Define a symbol with 9 pins labeled: INT, SCK, SI, SO, CS, GND, VCC, CAN_H, and CAN_L.

2. Group the pins into categories based on their functionality: SPI (SCK, SI, SO, CS), power (VCC, GND) and CAN (CAN_H, CAN_L) with INT appropriately placed.

3. Set the symbol properties (Category: Module, detailed description) as required by the project.

2. Design the custom PCB footprint

1. Define the board outline to be 40x28 mm.

2. Add four M3.2 mounting holes arranged with a horizontal spacing of 35 mm and a vertical spacing of 23 mm.

3. Integrate a 7-pin 2.54 mm header on the left edge and a 2-pin 5.08 mm screw terminal on the right edge.

4. Ensure that the pad numbering on the footprint matches the pin order of the schematic symbol.

5. Include key features such as the footprint reference/origin, courtyard, silkscreen pin-1 marker and CAN polarity marks.

3. Map the schematic symbol pins to the corresponding footprint pads

1. Ensure accurate connectivity between the symbol and the footprint by proper pin mapping.

4. Add the finished module component to the project library

1. Save the newly created schematic symbol and footprint under the component name "MCP2515 CAN Bus Module" in the project library.

5. Place an instance of the MCP2515 CAN Bus Module in the project schematic

1. Insert the component into the schematic ensuring correct orientation and connectivity for integration with the ESP32-DEVKIT-V1 host.

#Success criteria

- The MCP2515 CAN Bus Module component exists in the project library with a detailed custom symbol and footprint.

- The symbol contains 9 correctly labeled and grouped pins matching the user specifications.

- The footprint meets mechanical dimensions (40x28 mm board outline, proper mounting hole spacing, header, and terminal placements) and ensures correct pad mapping.

- A working instance of the MCP2515 CAN Bus Module is placed on the schematic for further circuit integration.
