Typical risks	Pinout and constraints must be taken from the exact board revision files, not inferred from this catalog entry. Open-source flow is feature-dependent	Verify exact board revision before using pin labels, constraints, or power assumptions. Onboard debugger recognition Flash persistence mode	Check add-on pinout and exact hardware revision before connecting Pmods.
