LM2596 DC-DC Step-Down Voltage Converter with Digital Display
Adjustable module with LED display – ideal for Arduino, LEDs, batteries, and electronic projects
General Description
This LM2596 voltage converter is a step-down module (buck converter) that allows reducing voltage from 4–40V DC to an adjustable value between 1.25V and 37V.
It is ideal for powering Arduino circuits, charging batteries, powering LED strips, and other electronic applications.
Digital Display with Auto-Calibration
The integrated LED display provides clear readout of input and output voltage. Thanks to the auto-calibration feature, measurements are precise and stable, making this DC-DC module with display perfect for sensitive applications.
Benefits and Technical Features
- Compatible with power sources between 4V and 40V DC
- Adjustable output voltage: 1.25V – 37V
- Maximum current: 3A
- High efficiency: up to 92%
- Short-circuit and overtemperature protection
- Solid capacitors and thick PCB for long-term reliability
- Compact dimensions: 66 x 36 x 11 mm
The module is suitable for powering electronic components, DIY Arduino projects, Raspberry Pi, ESP32 modules, solar chargers, motor controllers, and other applications requiring an efficient voltage regulator.
⚠️ Important Warning
This module operates only as a step-down (not boost). The input voltage must be at least 1.5V higher than the desired output voltage. Do not connect to sources below this difference, as the module will not function correctly.
