2.2 µH Shielded Inductor (2 A)Single-inductor (SIMO) element required by MAX77654 to generate all three SBB railsIHHP0806AZER2R2M0110806PDF
10 µF Ceramic Capacitor (X7R 25 V)Bulk output capacitance for each SBB rail to meet MAX77654 transient specs (CSBB0/1/2)C3216X7R1E106K160AB31206PDF
2.2 µF Ceramic Capacitor (X7R 16 V)Input/output caps for the two on-chip LDOs (CIN_LDOx, COUT_LDOx) recommended ≥ 2.2 µFC0805C225K4RAC312320805PDF
100 nF Ceramic Capacitor (X7R 16 V)High-frequency decoupling placed within 5 mm of ESP32-S3-MINI 3V3 pins (per Flux KB decoupling guidance)CC0402KRX7R7BB10440402PDF
Based on the Flux knowledge base recommendations:
  • Each power pin on the ESP32 module should have a 100 nF capacitor within 5 mm (decoupling best-practice).
  • Capacitor voltage ratings are kept below 60 % of their maximum to satisfy derating rules.
  • The inductor’s saturation current exceeds the SIMO peak requirements with a ≥40 % margin.
Would you like me to add these parts to your schematic now?
