1. Adjustable Output Voltage: The mini DC boost converter board allows you to set the output voltage to 5V, 8V, 9V, or 12V, with a default setting of 12V. This flexibility enables you to adapt the board to suit your specific power requirements. 2. Wide Input Voltage Range: The input voltage range for this DC step up module is 2.5V to 5V. It is important to that the input voltage remains lower than the set output voltage to safe and efficient operation. 3. Versatile Output Capabilities: When powered by a 3.7V lithium battery, this voltage regulator can deliver output options. It can provide 5V at 1A, 8V at 0.5A, 9V at 0.45A, and 12V at 0.3A. Alternatively, when using a 5V input, it can offer 8V at 0.7A, 9V at 0.7A, and 12V at 0.5A. 4. Efficient LED Indicator: The PCB board features an LED indicator that consumes approximately 1mA of power when the default output voltage is set to 12V. In case the LED is turned off, the input current is less than 1mA during no-load conditions. This ensures energy efficiency and helps conserve power. 5. Reliable Performance: With its adjustable output voltage, wide input voltage range, versatile output capabilities, and efficient LED indicator, this voltage boost module offers reliable performance for applications, including battery-powered devices, DIY electronics projects, and more. It provides stable and controlled voltages, ensuring the smooth operation of your connected components. Type: Voltage Regulator Condition: New Application: Computer Model Number: Mini DC Boost Converter Board 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 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.
