Planning Raspberry Pi Hat Creation.
Thinking deeply about your request.
Working on your request.
Your goal is a Raspberry Pi 3B+ HAT with two nRF24L01+ modules.
- I’ve prepared the plan.
- It covers HAT pin allocation, 2-layer/home-fab constraints, 0.4 mm minimum trace width, module integration, and final routing/review.
Click Start on the plan bar to begin. Let me know if you want any requirement changed first.
Plan
- Update the existing Raspberry Pi 3B+ HAT design to integrate two nRF24L01+ modules using common 2x4 2.54 mm header footprints, while maintaining the board-level constraints of a 2-layer layout, home fabrication friendly routing, and a 0.4 mm minimum trace width.
#Implementation plan
-
Schematic Update
- Add two instances of the 2x4 2.54 mm header footprint in the schematic for the nRF24L01+ module connections.
- Define the electrical connections for each header, ensuring proper alignment with shared signals if required by design.
- Validate the new schematic connections while retaining the original Raspberry Pi HAT interface.
-
PCB Layout Update
- Assign the placed header footprints to the PCB layout ensuring adherence to the Raspberry Pi 3B+ HAT form factor.
- Confirm that the layout respects the 2-layer board constraint, with a clear path for home-fabrication compliant trace routing (minimum trace width of 0.4 mm).
- Adjust the mechanical placement of the headers to prevent interference with other board connectors and maintain modularity.
-
Design Verification
- Review the integrated design for both electrical and mechanical integrity.
- Check that all routing complies with the minimum trace width and that the board architecture remains manufacturable with home fabrication methods.
#Success criteria
- The design incorporates two nRF24L01+ modules using standardized 2x4 2.54 mm header footprints.
- The PCB layout conforms to a 2-layer board with a 0.4 mm minimum trace width, suitable for home fabrication.
- The Raspberry Pi 3B+ HAT form factor is maintained and the header placements do not interfere with other board components.

Creating a concise plan.
Your goal is now a Raspberry Pi 3B+ HAT with two nRF24L01+ module connectors using common 2x4 2.54 mm headers.
- I updated the plan with that footprint requirement.
- It still preserves 2 layers, home fabrication, and 0.4 mm minimum trace width.
