Mini DC-DC Boost Step Up Converter Module 1.5A Can Set 5V 8V 9V 12V Selectable Voltage Regulator Output

The basic parameters
The output voltage can be set to 5 V / 8 V / 9 V / 12 V, the default value is 12 V
Input voltage range: 2.5V ~ VOUT-0.5V
Output performance: take the input of the 3.7 V lithium battery as an example, it can produce 5V1. 2A, 8V0. 7A, 9V0. 6A, 12V0. 5A. Make sure the input current and output current do not exceed.
Voltage adjustment Description

The front side of the PCB can be seen with the words A and B. The output voltage can be changed using the soldering iron to change the on-off pad. In the following table, 0 means that the pad is disconnected and 1 means that the pad is connected
