It is very important that you do not order a circuit board based on looks, many Balboa circuit boards look alike but have different software and or chips on them that changes the functionality and features. It is the firmware on the chip that manages the circuit board and gives it its unique functions. To correctly identify a circuit board the chip number should be used to identify it.
