SMUGDESK 3Pcs DCDC Boost Module 3.2V 3.7V to 5V

SKU CH-VVRV-16WBF

Three DCDC boost modules convert 3.2V or 3.7V lithium-ion batteries into stable 5V output for DIY electronics projects

  • 3-pack provides spare modules for multiple projects
  • Converts 3.2V or 3.7V lithium-ion batteries to stable 5V output
  • High-power design delivers steady current for demanding circuits
  • High conversion efficiency keeps heat generation low during operation
  • Compact circuit board fits easily into DIY electronics builds

Three-Module Pack for DIY Power Projects

This set provides three identical DC-DC boost modules that step up 3.2 V or 3.7 V lithium-ion battery voltage to a regulated 5 V rail. The boards suit hobbyists, students and engineers building portable gadgets, sensor nodes or USB charging circuits where a single-cell pack is the energy source.

Verify Your Battery and Load Requirements

Confirm that your cells deliver a nominal 3.2 V or 3.7 V and can supply enough current for the intended 5 V load. The module expects a single lithium-ion chemistry input; other chemistries or series-cell packs will not match the converter’s input range. Ensure the target device tolerates a fixed 5 V output before connecting.

Compact Boards for Tight Enclosures

Each module’s small footprint allows placement inside project boxes, wearable housings or breadboard layouts without crowding neighbouring components. The high-efficiency design keeps heat low, so no separate heatsink or forced airflow is needed in typical low-power applications. The three-piece bundle lets you equip multiple prototypes or keep spares for future builds.

Questions about this item

What comes in the 3-piece pack and do I need any extra parts to use them?

The pack contains three DCDC boost modules that convert 3.2 V or 3.7 V lithium-ion battery power to a stable 5 V output. You will need to supply the battery and any wiring or enclosure for your project.

How do I decide which input voltage version to use with my battery?

Each module accepts either 3.2 V or 3.7 V input, so you can use the same board with both common lithium-ion cell voltages without selecting a separate version.

What does the 5 V output mean when the module is powering a real circuit?

The board steps up the battery voltage to a steady 5 V rail with high conversion efficiency and low heat, making it suitable for DIY electronics, small equipment and charging modules.
