This module is small sized but has a very efficient booster chip that step-up your input voltage to a higher voltage for your need, for example boosting voltage for your robot for more powerful movement!

Note : Like other conversion booster chip, it will still take more current to convert your input voltage to higher output power.

Instruction to use

Please turn the potentiometer trimmer on the module and measure the voltage level using a multimeter (set the voltmeter 20V mode) to adjust the output voltage from this module. You may need to turn the potentiometer trimmer many times to see the changes in output voltage, turn right to increase the voltage level or turn left to decrease the voltage level. Soldering is required to use this module!

About the MT3608 chip

The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small in-rush current to extend battery life.
