The LM2596 regulator is a monolithic integrated circuit ideally suited for easy and convenient design of a step−down switching regulator (buck converter). It is capable of driving a 3.0A load with excellent line and load regulation. This regulator module is suitable for voltage converting circuits in your project. The blue terminal block on the module is to input power when the two rows of pins are to output power – one for positive (marked with "+") and the other for GND.

- INPUT - DC 3.3V to 12V, no boost.
- OUTPUT - DC 3 V to 5 V, the maximum output current is 3 A.
- RICH PINS- Output enabled by pins so more modules can be powered.
- PIN EXTENSION - provided with a soldering pad for a terminal block of power output.
- DIMENSIONS - 25 x 50 x 16 mm (0.98 x 1.97 x 0.63 inch).
- Voltage regulator for vehicles
- Power supply for electronic devices. When a 5v supply is needed, the module can be used to reduce a larger voltage and so you can get a 5v supply
- Step-down DC-DC Converter Module x 1
The price sure was right.I was a little surprised it only selects specific voltages, turning the pot does not allow you to select any voltage, just the preset ones. However,the selectable ones are good.
The only problem was they had no protection for the pins and many got bent.Ordered 2 and they both showed up and worked well.
