The versatile air conditioner board is often used to start air conditioners that have electronic tolerance problems. Setting up this board is simple, but for the first time, be sure to get help from an expert for setting it up. All connections are marked. This board contains an athyc 1504 memory IC, a yydz-2015428 microcontroller, and two uln 2003 ICs. We will learn how to test this circuit without connecting to city power in this video.
