30pcs Mini DC-DC Boost Step Up Converter

Output voltage:can be set to 5V/8V/9V/12V, default is 12V Input voltage range:2.5V-5V, input voltage must be lower than the set output voltage Type:Voltage Regulator Model Number:Mini DC Boost Converter Board Output capacity:5V 1A, 8V 0.5A, 9V 0.45A, 12V 0.3A when using 3.7V lithium battery input Using 5V input:8V 0.7A, 9V 0.7A, 12V 0.5A can be output Default output 12V:LED indicator consumes about 1MA. Tip:If the indicator light is off, the input current is less than 1MA at no load Voltage setting: The front of the PCB can be seen marked with the characters A,B. The output voltage can be changed by changing the pads next to the characters using a soldering iron, 0 in the table below means that the pads are disconnected, 1 means that the welding is connected; The pad next to the LED indicator can also be disconnected to turn off the indicator.
