Professional ESP32-based AC phase-control dimmer for fan speed control with optical isolation and safety features
This directory contains PCB layout files for the ESP32 AC Dimmer Fan Controller.
⚡ HIGH VOLTAGE WARNING: This PCB handles mains AC voltage. Only qualified personnel should fabricate and assemble. See SAFETY.md.
CRITICAL: The 8mm creepage distance between mains and low voltage sections is a safety requirement and must not be violated.
