LM2596 DC-DC Step-Down (Buck) Adjustable Voltage Regulator Module
High-efficiency switching buck regulator step-down converter capable of driving a 3A load with excellent line and load regulation.
LM2596 DC-DC Step-Down (Buck) Adjustable Voltage Regulator Module is an original, pre-tested electronic module designed for Arduino, ESP32, Raspberry Pi, robotics, and embedded engineering projects. Includes verified pinout compatibility and nationwide express shipping across Pakistan.
The LM2596 DC-DC Step-Down Converter is the ultimate power supply module for electronics makers and students. It efficiently steps down high DC voltages (such as 12V, 24V, or 36V) to stable 5V, 3.3V, or custom voltage rails.
Key Engineering Features:
- High Conversion Efficiency: Up to 92% switching efficiency, generating significantly less heat than linear regulators like 7805.
- Precision Multi-Turn Potentiometer: Easily tune output voltage down to the exact decimal with a screwdriver.
- High Current Output: Provides up to 3A maximum output current (2A continuous without extra heatsink).
- Solid State SMT Capacitors: Low-ESR input and output capacitors filter out switching ripple for sensitive logic boards.
Common Engineering Applications:
- Stepping down 12V lead-acid or 3S/4S LiPo batteries to 5V for Arduino/Raspberry Pi
- Powering high-current servo motors and LED strips
- Solar panel battery charging regulator circuits
- Industrial automation 24V to 5V control panel power supply
What's Included in the Package:
- 1x LM2596 DC-DC Step-Down (Buck) Adjustable Voltage Regulator Board
Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
