There are several older model WeMos-D1 being sold as WeMos-D1R2 to unsuspecting customers by several other vendors. The quality of the product is good and has a short delivery time, about two weeks to the US. I bought my WeMos-D1R2 from Banggood, I believe it is a Hong Kong based online retailer.
You have to make sure you have the current version of the board WeMos-D1R2. If you are not careful you will end up with a D1 Board which is an older version. There are two WeMos boards in the market. Apparently several shields, sensors and output devices that are manufactured for the Arduino platform will work on the WeMos-D1R2 with the added advantage of builtin WiFi. That means the board looks and works (in most cases) like an UNO. WeMos-D1R2 is an ESP8266-12 based WiFi enabled microprocessor unit on a Arduino-UNO footprint. In this Instructable I will guide you through the steps needed to install, configure and program the WeMos-D1R2 board using the Arduino IDE.
