5. Lamp beads requirements:
The circuit board uses white lamp beads or lamp strings by default. When using the lamp string, the built-in lamp beads of the lamp string are connected in parallel. If you use other colors of lamp beads,
It is possible that the battery discharge current increases. The lamp bead is directly connected to the circuit board without current limiting resistor. In the case of batches, you can customize the circuit board to use other colors of lamp beads, or adjust the parameters yourself. For specific adjustment methods, please see Chapter 6.
This circuit board is not suitable for connecting LED lamp beads with built-in chips, so avoid!!

6. Battery discharge current adjustment:
When the battery voltage and the color of the lamp bead have been determined, the discharge current of the battery is determined by the inductance.
The default inductance is 100uH. When the battery voltage is 1.2V and the white light is used,
The discharge current of the battery end is about 30m4. When using other colors of lamp beads, you can change the inductance to obtain the discharge current you need, and increase the inductance to reduce the discharge current.
Reduce the inductance and increase the discharge current. The discharge current of the battery terminal needs to be controlled between 10 and 135mA. Exceeding this current range will damage the circuit board.

7. Welding requirements:
1. The circuit board uses a large-scale integrated circuit chip, which is sensitive to static electricity, and anti-static measures must be taken when soldering.
Otherwise it will damage the circuit board;
2. When assembling the lamps, the lamp beads should be welded first, and then the solar panels and batteries should be welded strictly in accordance with this process.
Otherwise it will cause damage to the circuit board.

8. Light control function:
The circuit board automatically controls the light on and off by detecting the voltage level of the solar panel, without manual intervention in the whole process.
To achieve the purpose of charging during the day and automatically turning on the lights at night.
