If you are having problems determining which Balboa circuit board you have, you can identify it by looking at the chipset number on the top of the circuit board. In a large amount of cases, the white sticker that Balboa uses on their circuit boards falls off after years of dust and dirt, and general use.  If this happens, it is often difficult to determine which circuit board is in the system.  If you look at the top of the circuit board on the largest chip, there will be a chipset number.  You can use that number to cross reference the circuit board part number by using the cross reference below.
