The WeMos D1 R2 Uno based ESP8266 is a wireless 802.11 (Wifi) microcontroller development board compatible with the Arduino IDE. It turns the very popular ESP8266 wireless (WiFi) module into a fully fledged development board. The layout of this board is based on a standard Arduino hardware design with similar proportions to the Arduino Uno and Leonardo. It also includes a set of standard Arduino headers which means many existing Arduino shields can be plugged directly into the board (see note below).

The development board also includes a CH340 USB to serial interface giving it the ability to be connected and programmed directly from your computer and requiring only a common micro USB cable – no additional interface hardware or configuration is required. Once connected to the computer, and drivers have been installed, the WeMos D1 will appear as a standard serial COM port. The WeMos D1 can be programmed directly from the Arduino Integrated Development Environment (IDE) which is freely available for download from the Arduino website (arduino.cc).

Direct Arduino IDE support for this development board can be added with just a few mouse clicks via the built-in board manager feature. Programming the WeMos D1 via the IDE is then as straight-forward as programming any standard Arduino development board. Many of the default Arduino commands will work, including digital and analogue pin functions, and many examples are included in the IDE which demonstrate how to take advantage of the ESP8266s WiFi capabilities. These examples range from simply blinking an LED to turning the WeMos D1 into a stand-alone web server.

To quickly get going we have provided an Arduino setup guide on our blog site here:

Please note: This board requires a USB driver to be installed. Currently supported operating systems include all 32 & 64 bit versions of Windows 7,8, & 10. Drivers can be found at the bottom of this post.

This a 3.3V development board and is not compatible with 5V hardware. Please check compatibility before purchasing Arduino shields.

Example Arduino Blink Sketch:

Code:
/* HCDVBD0027 Blink example - HobbyComponents.com */

#include <ESP8266WiFi.h>

#define PIN 2               // Flash the LED connected to GPIO2

void setup()
{
  pinMode(PIN, OUTPUT);     // Set the pin to an output
}


void loop()
{
  digitalWrite(PIN, LOW);   // Turn the LED on 
  delay(1000);              // Wait for a second
  digitalWrite(PIN, HIGH);  // Turn the LED off
  delay(1000);              // Wait for another second
}

Just followed your Get Blinky Tutorial for the WEMOS D1.
I'm running win7 64 win the latest Arduino Ide.

I just wanted to let you know the blink sketch worked fine no problems

So I now have my Wemos esp Development environment up and running thanks to your tutorial. :D

Thanks

Andy
