It belongs with the iot & wireless, power & battery and usb & debug tools designs in this gallery.

From the project

An ESP32-based home automation controller designed in KiCad combines an isolated AC-DC power supply, dual relay outputs, physical switch input, and UART programming header into a single board for controlling AC loads (lights, appliances, etc.) over WiFi.

A mains-powered, WiFi/Bluetooth-enabled 2-channel relay controller designed in KiCad, built around the ESP32-WROOM-32. Designed for switching mains-connected loads (lights, appliances, etc.) with manual switch override, status LEDs, and a dedicated UART header for programming and debugging.

Home automation projects need a safe, reliable way to let a microcontroller switch mains-voltage loads without exposing the low-voltage logic circuitry to mains hazards or noise. This board handles that end-to-end: an isolated AC-DC module supplies clean low-voltage power, optocouplers electrically…
