Supply voltage: DC5V Welding details tips: 1. There are silk-screen logos of various components printed on the PCB board. Please refer to the silk-screen logo for soldering. 2. Resistors have no direction, but different resistance values. Please pay attention to the distinction when connecting 3. The long leg with a foot is positive (+), and the short leg is negative (-); pay attention to the silk-screen direction corresponding to the PCB board when soldering 4. When connecting the power cord to the terminal block, pay attention to distinguish the positive and negative poles, and do not connect them in reverse. 5. The welding sequence is from low to high, from small to large, and from inside to outside. 6. The soldering temperature of the soldering iron is 320°-380°, and the soldering time is about 3-5 seconds. Do not solder for a long time! In order to avoid damaging the ground wire of the circuit board. 7. The circuit board logo VCC is positive and GND is negative. 8. Pay attention to static electricity and the power supply size of the product to avoid burning the circuit and components.
