If you ever tried to tinker around the ESP8266-01 you've probably realised you can't plug it in directly on your breadboardThen you also realized it doesn't run on 5V, so you need to convert the voltage down to 3.3V.And afterwards you realized your ESP doesn't boot up because of initial current spike.Well this board solves all of these problems.

Here are its specs:

  • 3.3V Regulator SPX3819
  • 40uF Capacitance on Power Lines
  • Power LED
  • GPIO D2 LED
  • RST Switch
  • Boot Switch

Why didn't you add logic level converters in it, so it can easily programmed with Arduino?

  Are you sure? yes | no

The esp can easily take 5v on the logic pins so there is no need

  Are you sure? yes | no

did you mean to say that tx /rx pins pf esp01 can handle 5v ?

  Are you sure? yes | no

Yes

  Are you sure? yes | no

but i read in data sheet of esp01 that maximum Voltage of 3.3 volts for any pins

  Are you sure? yes | no

Check this thread. I also speak from experience using the esp8266

  Are you sure? yes | no
