Simple ESP8266 breakout board for programming with USB-TTL

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.
