Attention :
This is a high-power boost module. Please pay attention to the following when using:
1 The power supply must be sufficient. If the module needs to output 25W power, the power supply must be greater than 35W.
2 The power and boost module leads must be thick enough (can pass 10A) and soldered well.
3 Use a multimeter to directly measure the ''IN+ IN-'' port to determine if the power is sufficient. If the voltage is lower than the power supply 1V, the power supply is insufficient or there is no good connection.
4 Input voltage can not be greater than the maximum input range
5 Output power can not be greater than the maximum load for a long time
6 Input power must be greater than the output power, because the power consumption of the module itself
Applications:
for QC2.0 3.0 charger
for 3.7V li-on Lipo Lithium Battery 18650
PTZ CCTV IP camera
Smart home / home automation

LED Motor Driver
1 CELL Lithium Battery to 2-5 CELL Output
For short-term maximum input and output current, please refer to the table below. For long-term use, please add a heat sink or reduce the output current to 60%.
When used to drive inductive loads or motors, please pay attention to the following:
1 Please note that the starting current of the motor is greater than 3 times the rated current.
2 Please ensure that the power supply is sufficient.
3 Please connect a diode or drive circuit between the module and the motor.
It can be set to any voltage between 4.5-24V by changing the R1 resistor.
