Si4463 and STM32U575 Design Inquiry

flux

You want a new design that combines the Si4463 with an STM32U575.
  • I made a plan covering:
    1. RF requirements and band/antenna choices
    2. MCU-to-radio architecture, clocks, reset, and SWD
    3. Power rails, decoupling, and low-power operation
    4. PCB RF layout, grounding, and keepouts
Click Start on the plan bar to build it.
Since this is a part project, a fresh project is the right place to do it: Create new project.

Use lithium batteries for power supply

flux

You want the Si4463 + STM32U575 design updated to use a lithium battery supply.
  • I updated the plan to include:
    1. Battery-powered system requirements
    2. Lithium battery power path and regulation
    3. Optional charging/battery-management stage
    4. Validation that both ICs are powered correctly
Click Start on the plan bar to build it. The lithium-battery requirement is now captured in the plan.
