Step-Down buck converter from 4.5v-24v to 5V 3A (4R7 output adjustable) (OT253-B47)

high quality step down power converter with an efficiency of 97.5% at 6.5v to 5V at 0.7A and relatively little heat development. The efficiency is 94% at 12V to 5V at 1A.
Power supply 4.5v to 24v
Variable output voltage between 0.8v and 17v by means of potentiometer so that you can select very unusual voltages, very handy!
In addition, there are a number of fixed values: - 1.8V - 2.5V - 3.3V - 5V - 9V - 12V
Maximum output voltage: 3A at 5VConitnu output voltage: 2.1A
Dimensions: 20x11x5mm
User manual:
This module has 4 connections: - VO+ (Output current +) - GND (Ground / min) - IN+ (Input current +) - EN (Enable, if this is switched low there will be no more current flowing)
The ground / - of both input and output are connected to GND.

The solder points on the back of the board are actually solderable jumpers. It is not the intention to solder wiring to these but purely intended for selecting 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) is soldered. If you want to use one of the fixed voltages (1.8V, 2.5V, 3.3V, 5V, 9V or 12V) then the connection at ADJ must be broken. This can be cut with a sharp small knife. Then you solder a connection at the desired voltage.
