Installation guidelines:

After receiving the goods, it is recommended to check all the parts and components, and then assemble after the measurement, so that the components are also understood, easy to install, reduce errors, and quickly deal with problems. Electronic products are highly rigorous, and it is not possible to install a wrong part. Therefore, pay attention to the polarity and pin position of the component. You must ensure that each component is installed correctly. Refer to the installation guidelines when installing to ensure the successful installation of the driver board. After installation, check it again, confirm that it is correct and then power on, pay attention to the polarity of the power supply! Reverse connection may cause the components to burn out! It is recommended to string a resistance below 100 ohms during the test, so that it can play a protective role when there is a problem. At the same time, you can also power on first, and then install the integrated block chip when the circuit is not abnormal, so as to avoid damage to the IC. When 12V is input, the voltage of A and B output terminals to ground (negative electrode) is about: 5-6V. If not, please check the totem triode and peripheral parts! Especially the triode, it is easy to install errors. Also about frequency! Generally, it is clockwise. When the chaos is unknown, and there is no oscilloscope, adjust the potentiometer to 15K, or replace the potentiometer with a 15K resistor. At this time, the frequency is about 20KHZ, and it can also be adjusted to 50HZ. (105 capacitors). Put on the machine after assembly and testing! ! !
