Circuit board volume size: length 20mm * width 10m. Applicable occasions: 1. Solar single and double-sided road studs, solar ship warning lights, solar outline lights, solar navigation lights; 2. Home solar landscape lights, solar mason light jars, solar lawn lights, solar Christmas lights, solar starry solar string lights, etc., and light-sensitive switch lights. Electrical parameters: Solar panel voltage is about 2V Solar panel current≤120mA Battery specifications: single-cell NiMH No. 5 or No. 7 rechargeable battery Battery capacity: about 600mAH is recommended Battery discharge current: about 30mA (can also be customized) Flashing frequency: no flashing, (Need to flash, our store has a flash version. ) Lamp beads requirements: The circuit board uses white lamp beads or lamp strings by default. When using lamp strings, the lamp beads built in the lamp string are connected in parallel. If using Lamp beads of other colors may have an increase in battery discharge current. The lamp beads are directly connected to the circuit board without current limiting resistance. In batches, the circuit board can be customized to use lamp beads of other colors, or the parameters can be adjusted by themselves.Please refer to Chapter 6 for specific adjustment methods. This circuit board is not suitable for connecting the LED lamp beads with built-in chips. Battery discharge current adjustment: In the case that the battery voltage and the color of the lamp beads are fixed, the battery discharge current is determined by the inductance. The default inductance is 100uH. When the battery voltage is 1.2V, the white end is used. The discharge current is about 30mA. When using other color lamp beads, you can obtain the discharge current you need by changing the inductance of the inductance. The discharge current decreases when the inductance is increased, and the discharge current increases when the inductance is reduced. The battery discharge current needs to be controlled at 10 Between 135mA, exceeding this current range will damage the circuit board. Welding requirements: 1. The circuit board uses a large-scale integrated circuit chip, the chip is sensitive to static electricity, and anti-static measures need to be taken during soldering, otherwise the circuit board will be damaged; 2. When assembling the lamp, the lamp bead should be soldered first, and then the solar panel and battery should be soldered. It is necessary to strictly follow this procedure, otherwise the circuit board will be damaged. Light control function: The circuit board automatically controls the lighting and extinction by detecting the voltage level of the solar cell panel. The whole process does not require manual intervention to achieve the purpose of charging during the day and automatically lighting at night. Package include: 1Pcs Solar Light Controlled Board
