Arduino Uno R3-compatible with ESP8266 and external Antenna

If you need to connect an ESP8266 WiFi module to an Arduino Uno R3-compatible board, then save time and a lot of effort with this Arduino Uno R3-compatible with ESP8266 and external Antenna from PMD Way. 

You get an Arduino Uno R3-compatible board with onboard ESP8266, 8MB flash memory for the ESP, a PCB antenna and an external antenna for improved radio range. 

A USB cable is also included for your convenience. And free delivery, worldwide!

Using the onboard DIP switches, you can connect the Arduino to the USB interface, or the ESP8266 to the USB interface, or the ESP8266 to the Arduino via GPIO for interfacing between the two platforms. Thus you can easily upload firmware to the ESP or Arduino (click image to enlarge):

If you have selected the Mega328+ESP8266 switch settings - the ESP's TX/RX are connected to the matching Arduino RX/TX pins (D0/D1).
