Adjustable step-up step-down buck boost converter
As mentioned in the description a step-up step-down, buck-boost converter board will keep a pre-set voltage even if the voltage is below (step-up) or above (step down) the pre-set value. It works especially great where the power source fluctuates a lot e.g. solar panels.
Please note that the trim pot that is used to adjust the output of the module needs to be turned quite a few times before you can see a change in the output.
