1-100pcs 3.7V To 12V Mini DC-DC Boost Module Supports 5V/8V/9V/12V Output Lithium Battery Boost

Product description:
Output voltage can be set to 5V/8V/9V/12V, default 12V
Input voltage range: 25V-5V OUT.
Input voltage needs to be lower than = set output voltage
Output capability: when input with 3.7V lithium battery,
Can output 5V1A,
8V0.5A, 9V0.45A,
12V0.3A .
When input at 5V, it can output 8V0.7A, 9V0.7A, 1 2V0.5A
When the default 12V output, the LED indicator consumes about 1mA of current
If the indicator light is turned off, the input current is < 1mA at no load
Product size: 22*11mm

Voltage settings:
The words A and B can be seen on the front of the PCB. Use a soldering iron to change the words.
The output voltage can be changed by switching the pad next to the symbol on and off. In the table below, 0 means soldering
Disk is disconnected, 1 means welding is connected
The pad next to the LED indicator can also be disconnected to turn off the indicator
