Board is equipped with reset button, which is located at 
the top of the front side (

Figure 4-2

).  If you want to 

reset the circuit, press the reset button. It will generate 
low voltage  level on microcontroller reset pin (input).  In 
addition, a reset can be externally provided through 

pin 

27

 on side headers (

Figure 4-3

).

You can also solder additional reset button 
on the appropriate place at the back side 
of the board,
