Nordic Spa Circuit Board

Over the years, Balboa Water Group® has manufactured hundreds of circuit boards for many different spa manufacturers. It is very important that you do not order a circuit board based on looks; several boards look alike but have different software or chips. It is the chip that drives the board and gives it its unique functions. To correctly identify a circuit board, the chip number should be used to identify it. It can be found on a white sticker near the center of the circuit board*. Another number that helps identify a Balboa® circuit board is the five-digit number found on most boards (5****).
