Frequently asked questions
How do I set the output voltage?
Turn the onboard potentiometer while measuring the output with a multimeter, and set the voltage before connecting your load.
Is it a boost or a buck converter?
It is a buck converter, so it only steps voltage down. The output must stay below the input voltage.
