  • Remember that it's very important that you don't order a circuit board based on looks (several boards look alike but have different software or chips). Some circuit boards come with a large variety of software. Be sure to order the correct one for your needs.

    As with all electrical items once a circuit board has been installed, we cannot take it back other than for manufacturer's warranty.
