This is LM2596 2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3 ~ 37V, it comes with a built-in voltmeter display and uses an advanced microcontroller. Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.
Notes: Maximum current is dependent on input and output voltages, ambient temperature and cooling. To achieve maximum ratings an external heatsink may be required. Maximum LM2596 operating temperature must not exceed 125°C otherwise permanent thermal damage can occur.

Features :

  1. Input reverse polarity protection
  2. Built-in output short protection function
  3. The built-in thermal shutdown function
  4. Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.
  5. Power-off memory function, show that road after power voltage values measured for the last time
  6. Press the touch button for 3 seconds to turn off the LED display, touch the button again to turn on the LED display
  7. The band terminals, no iron can also be easy to use, and retention wire connection point

Package Includes :

1 x LM2596 2A Buck Step-down Power Converter Module.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
