## Overview

The Teyleten Robot LM2596S is a high-precision buck converter module featuring a wide input voltage range (4.5-40V) and adjustable output (1.25-37V) with up to 2A current capacity. It includes an integrated LED voltmeter with ±0.05V accuracy and a smart toggle button for input/output voltage display, making it an essential tool for engineers, DIY enthusiasts, and professionals seeking reliable, customizable power solutions.

## Description

Can only buck but not boost,This module can be applied to fields in the input voltage is higher than the step-down output voltage, such as batteries, power transformers, DIY adjustable power supply, 24V Car T of the power equipment industry buck, 12V switch 3.3V, 12V switch 5V, 24V switch 5V, 24V switch 12V, 36V 24V turn and so on.

Review: Adjust the Potentiometer - At first I thought all five boards were bad. I adjusted the potentiomemters but the output voltage never changed. I connected an ohmmeter on the pots and saw they read about 2k ohms. I turned the the pot screw a thousand bazzilion times counter clock wise before the resistance changed. Once they are adjusted to 500ish ohms the output voltage was easily adjustable. Other than this they work as advertised and are a good little board. I like the voltage display so I don't have to dig out my voltmeter everytime I need to adjust it.
Review: You need to use a meter to get accurate output Amended - This item seems to work good I just received them and haven`t put them into use. I hooked them up to a 16v laptop power supply the input voltage showed 16.6 volts so the input readings are accurate. When setting the output voltage I was needing 12v,9v, and 5v to get a reading of 12 volts the output had to be turned down to 10.0 on the display. to get a 5 volt output the display reading had to be at 3.4 volts so make sure you use a voltmeter when setting the output or you might be burning you project up with too much voltage!!!!! As far as life of the converter in use time will tell, if I see they do not hold up I will be changing my review but so far they have a 5 star from me. I am amending my review the battery in my voltmeter was almost dead when I started setting these converters since replacing it these converters are within a few tenths of a volt when setting the output voltage so as long as they last in use I have to change my rating from a 4 star to a 5 star rating.

## Features

- Adjustable output voltage range of 1.25V ~ 37V continuously adjustable. (Input voltage must be higher than the output voltage of 1.5V)
- With a voltage meter and voltmeter displays self-calibration. Uses a more advanced microprocessor voltage voltmeter error ± 0.05V, Range 0 ~ 40V. (To ensure accuracy voltmeter, make sure the input voltage of 4.5V and above)
- Touch of a button to switch the input or output voltage measurements and has a light show which is being measured voltages, and save the settings, even the power off and then on
- Input Voltage 4.5~ 40V. (Input voltage must be higher than the output voltage of 1.5v or more)

### ⭐⭐⭐⭐⭐ Perfect modern DC resistor
*by A***Z on May 13, 2024*

Used these for Daughter's high school physics project. powered by 9V battery, set up 3 circuits to power 1.5V Christmas light bulbs. One Circuit had 2 of these bulbs, which needs max 6V power supply, while the other two circuits with one bulb need 1.5V. These modern resistors are adjustable with a small flat screwdriver to supply the exact Voltage needed for the circuit. Can be utilized for other, more sophisticated projects. Recommend this product.
