2.8V-5.5V to 12V DC Power Conversion Module

Overview:
This product is a DC-DC step-up power supply module that can convert input voltages ranging from 2.8V to 5.5V to an output voltage of 12V. It is a compact and efficient module that can be used in a variety of applications, including powering electronic devices such as sensors, motors, and other electrical components. 3V~5.5V batteries (lithium batteries, nickel hydrogen batteries and 18650 battery series) can be used with this module to obtain the +/- 12V output voltage.
Note:
The -12V supply is lower 0.4-0.6V than the + 12V supply because of the partial voltage of the diode. Do not connect high-power loads to this module because of the small output current.

Features:
Low ripple and noise
Over-current and over-temperature protection
Small size and lightweight
Easy to use and install

Specification:
Input voltage range: 2.8V - 5.5V
Output voltage: 12V (fixed)
Maximum output current: 300mA
Conversion efficiency: up to 95%
Dimensions: 24mm x 12mm

User Instructions:
First, make sure that the input voltage (the voltage you're supplying to the module) is within the range of 2.8V to 5.5V. The output voltage of the module is fixed at 5V.
Connect your input power supply to the module, making sure to connect the positive and negative terminals correctly. You can use a battery or a DC power supply as the input.
Connect the load that you want to power to the output terminals of the module. Make sure to connect the positive and negative terminals correctly. The output voltage of the module should be 5V, which should be suitable for most electronic devices.
Turn on your input power supply. The module should start boosting the voltage from the input to the output, providing a stable 5V output for your load.
Monitor the module's temperature to make sure that it doesn't overheat. If the module gets too hot, it may shut down to protect itself. In this case, you should turn off the input power supply and let the module cool down before using it again.
