Mini multifunction boost module
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 ~ 11.5V VOUT-0.5V The input voltage must be lower than the set output voltage.
Output performance:
input 3.7V battery, output 5V 1A, 8V 0.5A, 9V 0.45A, 12V 0.3A
Input 5V, output 8V 0.7A, 9V 0.7A, 12V 0.5A
When the default 12V output, the LED indicator consumes about 1mA.
If the indicator is turned off, the input current is ?1mA at no load.
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.
A B VOUT
0 0 5 V
0 1 8 V
1 0 9 V
1 1 12 V
The pad next to the LED indicator can also be used to turned to turn off the indicator LED.
