About this product
A small DC-DC power module that converts an input between 1.5 V and 5 V into a fixed 3.3 V output, using boost or buck operation as needed. It is intended for powering 3.3 V circuits, sensors and low-power ICs from a low-voltage supply. The compact 11 x 7 mm size suits tight spaces.

Frequently asked questions
Can it power a 3.3V circuit from a single Li-ion cell?
Yes, a typical single Li-ion cell (about 3.0 to 4.2 V) falls within the 1.5 to 5 V input range.
What is the maximum output current?
The listing does not state the output current. Check the datasheet of the exact module before connecting high-current loads.
