Overview
Barely bigger than a postage stamp, the 3-01-0114 is HiLetgo's small audio amplifier module, rated at 6 watts of output. At under an inch in every dimension, it is a component board meant for building into a project rather than a standalone home theater amplifier.
This is sized and specified like a DIY electronics part, not a boxed consumer amplifier. The 6 watt rating and dimensions of under an inch point to a circuit board intended to be wired into a speaker enclosure, radio or other build. Buyers expecting a shelf amplifier for a home theater system are looking at the wrong category here.
- 6W rated amplifier board
- Under 1 inch footprint
- Component style, not boxed
- HiLetgo branded module
Who it's for
Hobbyists and makers needing a small amplifier board to wire into a DIY audio project are the target buyer here. Not a fit for anyone wanting a plug and play amplifier for a home theater or stereo system.
Pros and cons
- Small footprint fits inside custom builds
- Simple wattage rating for basic projects
- Not a standalone consumer amplifier
- Low 6 watt output limits use to small speakers
Performance notes
The board is rated for 6 watts of output, a level suited to small speakers rather than room filling volume. Its footprint of well under an inch per side means it is designed to sit inside another enclosure or device rather than function as a standalone unit.
