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 switch the pad on and off. In the table below, 0 means that the pad is disconnected and 1 means that the pad is connected.
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 the input 3.7V lithium battery as an example, it can output 5V1.2A, 8V0.7A,
9V0.6A, 12V0.5A
Please make sure the input current and output current do not exceed 1.5A.
