  • When ordering a circuit board, don’t rely on looks alone. Boards may appear similar but have different software or chips. The chip number is crucial as it drives the board and provides unique functions. To identify a circuit board accurately, use the chip number found on a white sticker near the center. Additionally, the five-digit number (5****) on most boards can also assist in identifying a Balboa Water Group® circuit board.
