Output adjustable step-down module 3A adjustable Input 4.5V-28V, Output 3.3/5/9/12V

Description

'This mini DC voltage of input voltages in the range of 4.5 – 28 volts to reduce output voltages between 3.3 – 12 V, and is therefore a so-called "step down voltage converter – to suit everyone it much space required. It is just 4 mm high and is suitable for all your smaller projects. A potentiometer This output voltage setting with ease.

This module has 4 connections:

VO+ (Output current +)

GND (Ground / min)

IN+ (Input current +)

EN (Enable, if this is switched low, no current will flow anymore)

Note : The ground / - of both input and output are connected to GND.

The soldering points on the back of the board are actually solderable jumpers. It is not the intention that wiring is soldered to this, but purely intended as the selection of the voltage.

By default, the module is set to provide a variable voltage via the potentiometer and can be set as desired. With a magnifying glass you can see that the last jumper (ADJ) has been soldered. If you want to use 1 of the fixed voltages (1.8V, 2.5V, 3.3V, 5V, 9V or 12V) then the connection must be disconnected at ADJ. This can be cut with a sharp small knife. Then you solder a connection at the desired voltage.
