When the battery voltage is lower than 3V, the charging module is in trickle mode, and the charging current is 300mA; When the battery voltage is greater than 3V, the charging module enters the constant current mode. At this time, it is charged at full speed according to the set target current, and the power can be about 21W; When the battery voltage rises to the charging target voltage (for example, 4.2V), the charging module enters the constant voltage mode. At this time, the current gradually decreases while the battery terminal voltage remains unchanged; When the charging current decreases to the charging cut-off current, the charging ends. After charging, if the battery voltage decreases to 0.1V lower than the target voltage, the charging is automatically restarted. (Note: if the voltage exceeds 4.2V, it is normal and the battery will not be damaged. If the voltage is 4.2V, the lamp is still flashing, it means that the battery is not fully charged. Full charge is not only based on the charging voltage.) There are 5 USB ports on the motherboard, which are type-a1 + type-a2 + micro-b + type-C + lightning.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
