Printed Circuit board 

All electrical components of EasyOne-CS are mounted on a single PCB. 

With the exception of the lithium battery no components can be serviced. 

The following two pictures show a top and bottom view of the PCB. 

 

Figure 7: Bottom view of EasyOne-CS PCB 

The lithium battery located on the top right of the PCB has an approximate life time of 5 to 10 years. In 
early revisions of the hardware the lithium battery is soldered on the board.
