Ten small green circuit boards with blue LED displays in a box

Batianda

Batianda LM2596S DC-DC Buck Converter 10 Pack 4.0-40V to 1.25-37V 3A Peak with LED Voltmeter

SKU CH-FYW3-S36X1

Pack of ten LM2596 buck converters that step 4.0–40 V input down to 1.25–37 V at up to 3 A peak, each with an integrated LED voltmeter

  • Precision LM2596 converter delivers enhanced voltage measurement accuracy
  • Input range 4.0-40V supports up to 3A peak current
  • Output adjustable from 1.25V to 37V for versatile projects
  • Integrated LED voltmeter with auto-calibration enables soldering-free setup
  • Ten modules packed in static bags inside a convenient storage box

Ten-module buck-converter kit

This pack contains ten LM2596S DC-DC step-down modules that accept an input range of 4.0-40V and deliver an adjustable output of 1.25-37V. Each board is rated for a maximum peak current of 3A and includes an integrated LED voltmeter with auto-calibration. The modules are supplied in a static-protected bag inside a storage box and require no soldering iron for basic assembly.

For hobbyists and repair technicians

The kit suits anyone building multiple voltage-regulated power rails for Arduino, sensor arrays or battery-charging projects where a compact buck converter with a built-in display is convenient. Buyers who need sustained currents above 3A, step-up or buck-boost topologies, or isolated outputs should look at other power-supply modules.

Adjustable 1.25-37V output range

The single specification that decides suitability is the output voltage window of 1.25V to 37V from a 4.0-40V source. If your load requires a voltage outside this span, or a negative rail, these modules will not meet the requirement.

Questions about this item

How do I wire the Batianda LM2596S module and which step is often missed?

Connect the source to the 4.0-40V input terminals, then turn the onboard potentiometer until the integrated LED voltmeter shows the desired 1.25-37V output; the step many skip is verifying the output with a multimeter before applying a load.

What maintenance or replacement will the Batianda LM2596S need over time?

The LM2596S IC and electrolytic capacitors are the parts that age; expect to replace a module if the output voltage drifts, ripple increases, or the LED voltmeter reads inaccurately after extended operation.

What limit appears first when the Batianda LM2596S runs continuously at high current?

Thermal protection on the LM2596S chip activates before the 3A peak rating can be sustained; without added heatsinking the module will shut down or reduce output once the junction temperature limit is reached.
