ESP8266 wifi relay review - ruclipcom
/8/2018The 3. 3V regulator of the Uno can barely supply enough current for the ESP, let alone with a relay that draws quite a lot of current on top of that.
How to drive a relay from ESP8266 gpio - Stack Exchange
This my review of a ESP8266 wifi IOT relay board supplied by ICStation This is a module which can be controlled over its own access point, or connected to your wifi network.
Wifi IoT Relay Board Based on ESP8266 - ElectroDragon
Can you tell me the reason of reset in esp8266 v1 module while connected to relay with 220v. I have tried esp8266 with relay with 3. 3v and 5v, and it works perfectly. But when i connect 220v to relay and control relay with esp8266 the result is unpredictable. It works for a while (220V connected case).

This relay module has two channels (those blue cubes). There are other models with one, four and eight channels. This module should be powered with 5V, which is appropriate to use with an Arduino. There are other relay modules that are powered using 3. 3V, which is ideal for ESP32, ESP8266, and other microcontrollers. Get a relay module:
Problem with ESP8266 01 and a Relay - forumarduinocc
Relay modification part 3/3 (LED removal) I had to remove LED from relay, because GPIO current is low and LED current consumption is to high. With LEDs, relay clicking when GPIO is set to HIGH.
