Basic parameters The output voltage can be set to 5V/8V/9V/12V, the default is 12V Input voltage range: 2.5V~VOUT-0.5V Output performance: Take 3.7V lithium battery input as an example, it can output 5V1.2A, 8V0.7A, 9V0.6A, 12V0.5A. Make sure that the input current and output current do not exceed 1.5A. Voltage setting description The front side of the PCB can be seen with the words A and B. The output voltage can be changed by using the soldering iron to change the pad on and off. In the following table, 0 means the pad is disconnected and 1 means the pad is connected. A B VOUT 0 0 5V 0 1 8V 1 0 9V 1 1 12V The pad next to the LED indicator can also be turned off to turn off the indicator. Product size: 22 × 11 × 3.6mm
