We took a certified module with an onboard antenna, and plenty of pins, and soldered it onto our designed breakout PCBs. We added in:</p> <ul style="margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;"><li style=" margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Reset button,</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">User button that can also put the chip into bootloading mode,</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Red LED you can blink</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Level shifting on the UART and reset pin</li> <li style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">3.3V out, 500mA regulator (you'll want to assume the ESP8266 can draw up to 250mA so budget accordingly)</li> <li style=" margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Two diode-protected power inputs (one for a USB cable, another for a battery) </li></ul></body></html> Adafruit HUZZAH ESP8266 Breakout https://learn.adafruit.com/adafruit-huzzah-esp8266-breakout/overview X{instanceTitle} {net connector1} {net connector2} {net connector3} {net connector4} {net connector5} {net connector6} {net connector7} {net connector8} AD8210 ESP-12 Breakout A //obsolete//Breakout Boards 2471 GND

GPIO 12

GPIO 14

GPIO 16

This is the enable pin for the ESP8266, pulled high by default. When pulled down to ground momentarily it will reset the ESP8266 system.

Analog input pin, max 1.8V

this is the reset pin for the ESP8266, pulled high by default. When pulled down to ground momentarily it will reset the ESP8266 system

The TX pin is the output from the module and is 3.3V logic

The RX pin is the input into the module and is 5V compliant

GPIO 15

3.3V output from the regulator

Enable pin for the regulator. By default its pulled high, when connected to ground it will turn off the 3.3V regulator.
