Mini360 Module Pinout Configuration

This module is small in size and has only input and output pins. It also consists of an output adjustable potentiometer. The table below shows the pin configuration of the Mini360 buck module.

Note: The onboard potentiometer can be used to regulate the output voltage; it boosts up the output voltage when rotated clockwise whereas, bucks the output voltage when rotated counterclockwise.
