Mono Amplifier Board for DIY Audio

The HiLetgo TDA2050 module is a single-channel amplifier board built around the TDA2050 chip. It accepts DC or AC input from 5 to 24 volts and delivers 5 to 120 watts into 4 to 16 ohm speakers. The package contains two identical boards measuring 60 by 35 by 40 millimetres. It is intended for hobbyists and builders assembling custom speaker systems or repairing existing audio equipment.

Input Voltage Range 5 to 24 Volts

The supply voltage window of 5 to 24 volts is the critical specification that determines whether this board fits a project. Power sources must stay within this range and be limited to 500 milliamps or less; mobile phone outputs and truck electrical systems are explicitly unsuitable. Exceeding the voltage or current limits will degrade sound quality or damage the module. Correct polarity connection is also mandatory to prevent board failure.

Compact Module for Custom Speaker Builds

Each board measures 60 by 35 by 40 millimetres, allowing it to fit inside small enclosures or behind speaker panels. The two-board pack supports stereo configurations or separate mono zones without additional purchases. Builders must provide a compatible power supply, speakers rated for 4 to 16 ohms, and proper heat dissipation for the amplifier chip. The module frees the designer from sourcing discrete amplification components and simplifies wiring with its integrated layout.

Questions about this item

How loud will 120W actually get with this board?

At 120W into a 4-16 ohm speaker the module can drive typical PA or stage monitors to stage-volume levels; real output depends on supply voltage, speaker efficiency and heat-sinking.

What does the DC/AC 5-24V input range cap in practice?

The board accepts 5-24V DC or AC; exceeding 24V or drawing more than 500mA risks damage and degrades sound quality, so a regulated supply within that window is required.

Will the 60x35x40mm module fit my enclosure?

The board measures 60mm long, 35mm wide and 40mm tall including components; allow clearance for wiring and heatsink airflow when planning the mount.
