111 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other AV receivers and amplifiers, soundbars, home theater speakers, subwoofers, surround sound systems and Blu-ray players we track in this category on price, popularity and size.

Overview
The HiLetgo TDA2050 is a raw amplifier module built around the TDA2050 integrated circuit, priced at $11.49. It carries a 4.2 rating from 111 buyers, a reasonable vote of confidence for a bare board sold to hobbyists and DIY builders.
With a rated output of 120W, the TDA2050 chip is a well-regarded topology for budget audio projects. The module itself provides the power amplification stage only. Buyers are responsible for supplying their own power supply, enclosure, input wiring, and any passive components needed to complete a working amplifier.
This is not a consumer amplifier in the traditional sense. It belongs on a workbench, not in a living room AV rack. Buyers comfortable with electronics projects will find the HiLetgo board a usable, cheap platform. Anyone expecting a finished product will be disappointed.

Frequently asked questions
Does the HiLetgo TDA2050 come with a power supply?
No. The TDA2050 listing is for the amplifier board only. You will need to supply an appropriate DC power supply separately. The TDA2050 chip typically operates on a dual or single supply voltage, so check the board's documentation for the correct voltage range before powering it up.
Is this suitable for a home theater speaker setup?
The HiLetgo TDA2050 is designed for DIY projects, not direct home theater use. It lacks a case, volume control, and input connectors that a finished home theater amplifier requires. If you want a ready-to-use amplifier, consider a finished model instead. Questions about alternatives are welcome at hello@hometheaterbuilder.com.
