Be sure to mount male headers on your Wemos D1 Mini in the proper orientation. The RST pin should be in the upper left position. There are several good Arduino libraries from Sparkfun, Wemos, and Adafruit. This one is very good: https://github.com/squix78/esp8266-oled-ssd1306

1 oled shield came in a 'ring-size' case in anti-static bag. see pictures. all rolled-up in a thick piece of paper foam, sealed with tape. in short: appropriate package for the content. shipment took about 2 weeks to deliver (to France) in Feb 2017. no issue. Items are conform to order. with various 'legs' sizes to be soldered on the shields. They are much smaller than expected (even though I expected small pieces). OLED screen is small size: fits on a thumb nail. I hope I will be able to read information displayed once plugged. I am waiting for the Wemos ESP8266 to arrive so that I can plug everything together and start monitoring home temperature both on OLED screen and Domoticz web application. See sensor & oled pictures attached.
