Wemos D1 Mini Pinout

The wemos d1 and some other esp8266 boards are a bit different than other arduino boards in that their pin numbers refer to the gpio numbers but the labels you see on the silkscreen don t match the gpio numbers i guess because the board layout would have made the numbering non consectutive.

The most widely used esp8266 boards are the esp 01 esp8266 12e nodemcu kit and the wemos d1 mini. If you re using an esp8266 01 board you can use the following gpio diagram as a reference. The wemos d1 is a esp8266 wifi based board that uses the arduino layout with a operating voltage of 3 3v. However unlike the nodemcu it has one pin that can produce 5v.

The wemos d1 mini has a 3 3v and 5v output to power different external components. With that let s proceed on with the specifications of the. As far as pinout goes the wemos d1 mini is very much like the nodemcu albeit smaller. Because the wemos d1 mini is also based also on the esp8266 the possible pinout would be the same as the nodemcu.
