You can change the address of a backpack very easily. Look on the back to find the two or three A0, A1 or A2 solder jumpers. Each one of these is used to hardcode in the address. If a jumper is shorted with solder, that sets the address. '''A0''' sets the lowest bit with a value of '''1''', '''A1''' sets the middle bit with a value of '''2''' and '''A2''' sets the high bit with a value of '''4'''. | You can change the address of a backpack very easily.
