Buck Converter Voltage Kit (10-Pack)

A buck converter steps a higher input voltage down to a lower, regulated output — this 10-pack gives enough modules to power multiple sensors or boards from a single shared supply rather than needing a separate fixed-voltage adapter for each one. Ten modules cover a build with several different voltage rail needs at once.

Each board has an onboard trim potentiometer that adjusts the output voltage across a working range, letting the exact output be dialed in for whatever downstream component it's feeding — a 5V sensor, a 3.3V logic board, or anything else within the module's range.

The compact board footprint fits easily into a project enclosure without dominating the internal layout, and the input and output pads are clearly marked, avoiding the mix-up risk of wiring an input line into the output side.
