This is a rough (although dimensionally accurate) model of the LoLin NodeMcu development board. I use these to create small IOT projects around the house, and I use this model to use as a stand-in when designing enclosures and other implementations. I created this for two reasons: 1) I could not find a model elsewhere. 2) This particular version of the board is a bit wider than the other versions, so I thought it would be good to have a model of this variant created. (This is the version that has issues fitting in a single standard sized breadboard).
