Info
 

The D1 R2 is a WiFi capable ESP8266EX based development board in the form of the Arduino UNO board format.

This board is compatible with the Arduino IDE and with NodeMCU. Tutorials for each can be found in the resources section below.

The D1 R2 also features an on-board switching power supply which allows you to power the board from a power supply up to 12V.

We offer a board similar to this called the Wemos D1 Mini that is much smaller in size and breadboard-compatible.

Note: The D1 R2 is a 3.3V device. If you connect it to 5V digital sensors or devices you may need a logic-level converter such as our 4-channel or 8-channel logic-level converter modules.

Good construction, easy to setup. December 3, 2016
By: Ron from NY, United States  
This is my first ESP8266 board needed for some IoT tinkering.

The board itself is appears well made, good solder points, etc.

To get this working in the Arduino IDE you should be aware how to use GIT in your OS to load the board and libraries as per WeMos instructions. Really was not hard at all.

Loaded up the ESP8922 Blink sketch and WifiWebServer sketch and they worked like a charm.

The correct board and honest product description September 30, 2016
By: Chris Petzel from Muncie, IN United States  
I needed 17 Wemos D1 R2 boards for simple data acquisition needs in a production environment. After being bait-and-switched by an eBay seller with "functionally equivalent" clone boards, I searched for a reliable provider of these boards and found Addicore. I was impressed by the website's About Us page and product reviews so I gave Addicore a chance.

The boards they provide are legitimate Wemos D1 R2 and are also the revision that is specified in the product listing. I chose free shipping and even so, they were shipped the same day in a box (not a padded envelope like some other sellers).

Black is the New Black... July 19, 2016
By: Kurt Roesener from San Diego, CA United States  
These are the latest Version of this board:  

These are the 2 main upgraded items:
Uses BRT (Bias Resistor Transistor), easier to get into  flash mode.

Optimized the circuit, the board is more stable.
