Hardware

After selecting an SF32 device and validating a development-board baseline, use this section to design the board or module carrier and prepare it for production. Start with a reference design if one fits, follow the device-specific implementation guide, and assemble the evidence and design package needed for the production-readiness review.

Find a Guide

Choose the chip or module at the center of your design, then open the matching implementation material. Use the product introduction first if you still need to confirm the package, power baseline, memory tier, or integration approach.

Follow the Hardware Path

  1. Reuse a reference baseline when it fits. Reproduce its stated board and software baseline before adapting it; otherwise, begin directly with the selected device guide.
  2. Implement and review. Use the matching guide before schematic capture, then apply its checklist during schematic and layout review. Validate the intended software and peripheral path on the closest development board before freezing hardware. Development-board tests do not replace power, pin-function and RF validation on the final board.
  3. Use M2 materials when the carrier is intended to follow the M2 proposal. Apply the M2 naming rules and confirm the interface definition against the exact module before committing to the interface; the pin-level definition remains a draft.
  4. Verify CAD and component choices. Use CAD & Components to cross-check the symbol, footprint, package drawing, AVL, and critical component assumptions for the exact part.
  5. Close the release gate. Move to Design for Production with the design evidence, approved deviations, remaining risks, and manufacturing-test assumptions.

Continue Your Development

If the part, module, or board direction is still uncertain, return to SF32 Products. For a repeatable toolchain, flash, and serial-log baseline, use Getting Started. Continue to Develop for software implementation guidance that must be validated alongside the hardware.
