We have recently came across with 2 excellent products recently - the Wemos D1 mini esp8266 based development board and the Nextion USART based touch screen display.  Both of which are affordable, easy to use and quite powerful.

Therefore, we have decided to build an IO board which combines the 2 and will serve as the backbone of my future projects and hopefully should be useful for many others.


  • It can be used as a standalone wireless touch screen display. We will provide an API to expose the functions via HTTP requests.
  • Fit nicely to the display. The PCB and the display screw holes fit perfectly.
  • Open for extension / Closed for modification - all of the IO of the Wemos D1 mini are exposed and functionalities can be expanded, while keeping the IO board unchanged.  For example in the video, we have added thermometer and humidity sensors.
