Built the complete 44-component, 40-net ESP32-S3-FN8 schematic with native USB-C, protected power input, TLV62568 buck regulator, crystal, u.FL RF path, reset/boot buttons, and an 18-GPIO breakout. Independent review corrections were applied, including 22 Ω USB resistors and a low-capacitance RF ESD device.
