 Newer members of the Arduino supported family of units, this one specially made us curious.\\
 Development of sketches for this Wemos D1 or Lolin D1 was a challenge wich resulted in a very complete piece of software.\\

 But making a 5 Volt power line, is not a good idea.\\
 The power loss in many occasions might come unacceptable for a certain task, like servo's.\\
-Therefore, this board is equipped with a switching regulator, and the power supply for this unit can be anything between 12 and 24 Volt ac or dc.\\

 The switching regulator has a selection for the output voltage, which should be set to 5V.\\
 It can be done by the on-board trimmer, but I prefer to use the voltage selector on the bottom side of the regulator board.\\
