1. Choose Your Hardware Components: Start by deciding on the electrical components you'll need for your schematic. In this project, you're working with the L298N, a dual H-bridge motor driver, which allows you to control the direction and speed of two DC motors independently.
2. Create a Schematic: This is a symbolic representation of your circuit. Flux allows you to draw connections between your components. For example, you will need to connect different pins of the L298N to correspond with their respective functions (e.g., IN1, IN2, OUT1, and OUT2).
3. Design your PCB Layout: Once you have your schematic, Flux can generate a PCB layout automatically, but you will likely need to make adjustments. Think of the layout as a 3D representation of your schematic. It’s the same components and the same connections, but arranged in physical space. Adjust component placement, route traces, and add vias where necessary. When placing components, good practice is to group related components together and take into consideration the flow of your circuit.
4. Assign Footprints: This involves choosing the physical form each component will take on the actual board. For example, your L298N might come in a TO220-15 package as specified in the description.
5. Connecting Parts: Using Flux, you need to connect the different parts based on their functionality. For example, connecting input pins i.e. IN1, IN2, IN3, IN4 to corresponding signal sources, or connect driving pins like ENA, ENB to controlling units.
6. Generate Gerbers: These are manufacturing files that your PCB manufacturer uses to fabricate your PCB. Gerbers define copper layers, solder mask, silkscreen, and drill files. Flux can generate these for you.
7. Validate Design: Use the Design Rule Check (DRC) to check for common errors. It's important to use a DRC rule set provided by your PCB manufacturer as there are many industry standards.
8. Order the PCB: Once the design passes DRC checks, send the Gerber files to the PCB manufacturer of your choice.
9. Assemble: Finally, once you receive your PCBs from the manufacturer, you can solder your components to the PCB board.
