Using this Matek Servo PDB is easy. First, make sure the input voltage is within the 9V - 55V range. You can adjust the output voltage for your servos to 5V, 6V, or 8V as needed. Connect the components using the 2.54mm pins. When using, keep in mind that there's no protection for reversed input polarity, so double - check your connections. The PDB has thermal shutdown and overcurrent protection, but avoid overloading it. For stable 8V output, ensure the input voltage is at least 10V. Maintenance is simple. Just keep it clean and dry. If you notice any abnormal behavior like overheating or short - circuits, disconnect the power immediately. The package comes with unsoldered Dupont pins, so you may need to solder them properly according to your requirements.
