LQFP64 VCAP_1 pin description should specify 4.7 µF, not 2.2 µF

Data checked 2026-09-14: live ray/stm32f411ret6 page.json fetched using adom-wiki; manufacturer DS10314 Rev 8. This is a component documentation issue; no desktop bridge is involved.

The LQFP64 pin-30 VCAP_1 description currently says to connect a 2.2 µF low-ESR capacitor. This package has only one VCAP pin. ST specifies 4.7 µF with ESR <1 Ω for a single-VCAP package (VCAP operating-conditions table, page 66); the LQFP64 pinout is Figure 11, page 36.

Please correct the package-specific pin description and any minimum-circuit examples to 4.7 µF / ESR <1 Ω. Do not apply the two-VCAP 2.2 µF-per-pin recommendation to this LQFP64 part. The new local F411 molecule already uses 4.7 µF, while preserving the original wiki description as source evidence. This is a documentation correction request; no footprint/pin-number change is requested.
