Creating a proposed plan for circuit design.
I’ll design your circuit and provide concrete PCB placement recommendations for this board. Here’s the plan:
- Capture your circuit: add specified parts, set values/footprints.
- Wire everything completely (including POSITIVE and NEGATIVE); clear ERCs.
- Prepare PCB: verify footprints, set board size, choose a 4-layer stackup with an uninterrupted GND plane.
- Produce a placement proposal: minimize high‑current paths, group power, place decouplers at power pins, define keep‑outs.
- Review and iterate.

Plan
- Design a complete circuit and propose PCB placement recommendations for the 21700 Protected Button Top project by finalizing connections for the battery terminals (POSITIVE and NEGATIVE) and other required components. The goal is to ensure the schematic is fully connected and to deliver clear PCB layout guidelines that prioritize continuous ground planes, short high-current paths, and proper decoupling near power pins.
#Implementation plan
- Update and Complete the Schematic
- Add and configure any missing supporting components from the Flux library, such as battery protection elements if applicable.
- Connect the battery terminals (POSITIVE and NEGATIVE) to related circuit elements to complete power paths.
- Resolve ERC warnings by confirming all net connections are correctly assigned.
- Setup PCB Layout
- Verify and assign proper footprints for battery terminals and any added components.
- Define PCB parameters by setting board size based on component spread and selecting a 4-layer stackup with an uninterrupted ground plane.
- Develop Concrete PCB Placement Recommendations
- Place critical power paths including the battery terminals and protection circuitry in a manner that minimizes current path lengths.
- Group power-related components together to simplify routing and maintain thermal integrity.
- Place decoupling capacitors directly adjacent to power pins of active devices.
- Define clear keep-out zones to avoid interference with high-current and sensitive signal routing.
- Final Review and Iteration
- Review the schematic connections and assess the placement proposal against best practices for EMI and thermal performance.
- Prepare the project for final routing and layout finalization.
#Success criteria
- The schematic must show all nets and ERC warnings resolved, with complete connections between battery terminals and components.
- PCB layout guidelines are documented with specific placement instructions for battery terminals, decoupling components, and power sections, ensuring a continuous ground plane and optimum board layout for performance.
