ESP8266 breakout board
First Version of my ESP8266 Breakout Board.
Beside the pull up resistors for CH_PD, GPIO_0, GPIO_2 and RESET and the buttons to ground RESET and GPIO_0 (PROG).
I have also foreseen a pin header for connecting my CP2102 Serial Converter USB To TTL UART 6PIN Module.
The voltage supply is the USB-TTL and converted to 3.3v by the 1117.
There is a resistor on GPIO_16 for wake up after deep sleep and a two capacitors as voltage stabilizers.
