FQA Question 1: Why is power-free better than external power supply? Answer: External power supply uses wires to connect external 5V to the interface. Voltage lo will occur through wires. The larger the load, the greater the lo, the more unstable there will be. The power-free board takes 12V. After voltage reduction, interference removal and voltage stabilization, the output is stable 5V, and lo compensation is added, so there will be no shortage of power supply.
