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.
Details
Here are its specs:
3.3V Regulator SPX3819
40uF Capacitance on Power Lines

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