    Board Assembly
     
 
Push a screws (M2.5*6mm) up through the mounting hole on the underside of the Raspberry Pi.
 
Screw the spacer (M2.5*23mm) down until it is hand tight
 
     
Plugs the X720 board straight into your Raspberry Pi B+'s GPIO header and screw down (M2.5*6mm)
 
Optional -If need 2nd Ethernet and WOL function, connect X720 to Raspberry Pi with the USB to Micro-USB Cable
 
     
 
    Case Assembly
     
 
Mount the Raspberry Pi board onto the bottom case and screw down (M/F Hex standoff 23mm) using a socket spanner

 
a) Plugs the X720 board straight into your Raspberry Pi B+'s
    GPIO header
b) Double check polarity of battery's connector before
    placing 1860 batteries into the holder
     
a) screw down X720 board (M/F Hex standoff 21mm)
b) Connect the 4-pin cable from X720 to LED & switch board
c) Place the LED & switch board and screw down (M2.5*6mm)
 
  Optional to install the GPIO reference board, repeat step 3
     
     
  Screw the top cover down (M3*5mm)
 
a) Install the power switch cap
b) If need 2nd Ethernet and WOL function, connect X720 to Raspberry Pi with the USB to Micro-USB Cable
