Hi, I am looking for working pcb design of 4 channel wifi smart switch with fan dimmer using ESP8266 and triac (not relays) and an onboard power regulation of 230v to 3.3v (without using hilink or any similar products).all the components used must be SMD and the board should be as compact as possible. I will also need a sample arduino code for testing the board. I am attaching an image the one that I have built without fan dimmer for reference.
