Overview
The HiLetgo TDA2050 is an amplifier rated at 120 watts, built around the TDA2050 audio amplifier chip that gives the module its name. No dimensions or color are listed, consistent with HiLetgo's usual bare circuit board products.
HiLetgo primarily sells electronic components and modules rather than finished consumer audio gear, and the TDA2050 designation matches a well known mono amplifier integrated circuit used in DIY speaker and amp projects. Buyers should expect a circuit board rather than a boxed, cased amplifier ready to place on a shelf.

- 120W power rating
- HiLetgo brand
- Component level board, not a cased unit
Who it's for
Hobbyists and DIY audio builders comfortable wiring a bare amplifier board into their own project fit this listing. Anyone wanting a finished, cased amplifier with a remote and enclosure should look at a consumer branded unit instead.
Pros and cons
- 120W rated output
- Built around the well known TDA2050 chip
- Suited to DIY and hobbyist audio builds
- No case, dimensions or color listed
- Requires external power supply and heatsink
Performance notes
The TDA2050 chip at the core of this board is a mono Class AB amplifier IC, commonly wired into DIY builds with an external power supply, heatsink and enclosure supplied by the builder. The listed 120 watt rating describes the board's output capability, though actual clean output depends on the supply voltage and heatsinking the builder provides.
