Usage steps:
1. Wiring: IN+is the input positive pole, IN - is the input negative pole; OUT+is the output positive pole, OUT - is the output negative pole.
2. Connect the cable between the module and the power supply first, and then power on. Remember! Remember! If the input terminal is wired with electricity, it is prone to sparking, especially when the input power voltage is high, it may even scorch the solder pads of the module.
3. After selecting a suitable power supply and powering it on, use a multimeter or voltmeter to measure whether the output voltage of the module matches the voltage required by the equipment.
4. Electrical equipment or (load) is connected to the output terminal of the module.
Attention:
1. This is a buck power module, so please keep the input at least 4.0V higher than the output.
2. Input and output are not isolated, ensuring safety and reliability.
Package include:
1X buck module
