Green PCB amplifier board with blue potentiometer and power indicator LED

Ruth's sister

Ruth's sister TDA2030 Mono Amplifier Board international power cord

SKU CH-NXQ1-8M6P8

A mono amplifier board using a TDA2030A chip delivers up to 20 W from a 6–12 V supply and includes an onboard 10 k volume control, power indicator and speaker socket

  • TDA2030A chip delivers 18 W mono output
  • Onboard 10 k potentiometer gives precise volume control
  • Built-in power indicator shows operating status at a glance
  • Exposed main pins allow direct signal input without extra wiring
  • Compact 31.6 x 23.2 mm PCB fits tight enclosures

Amplifier Board Purpose

The Ruth's sister TDA2030 mono amplifier board is a compact PCB module built around the TDA2030A power amplifier chip. It targets hobbyists and repair technicians who need a simple, single-channel audio amplifier for low-power speaker projects or bench testing.

Build Integration

The board operates on a 6 to 12 volt supply and measures approximately 31.6 by 23.2 millimetres, so it fits inside small enclosures or prototype cases. An onboard 10 k adjustable resistance provides volume control without external potentiometers, while a power indicator LED confirms operation at a glance. The chip's main pins are exposed for direct signal input and the socket accepts a speaker connection.

Output Capacity

Maximum output per channel is rated at 20 watts with the mono circuit designed for 18 watts of continuous power. This headroom suits small bookshelf speakers, desktop audio experiments or portable battery-powered builds. It will not drive larger room-filling speakers or multi-channel surround systems that demand higher sustained power.

Questions about this item

How much power can the TDA2030 board deliver continuously before thermal limits appear?

The module is rated for 18 W mono output and a maximum of 20 W per channel when driven within the 6–12 V supply range.

What heat or noise should I expect when the amplifier runs all day at full volume?

The bare PCB has no fan or heatsink fitted; the TDA2030A chip will warm up under continuous 18 W load, so external cooling is advisable for all-day use.

What power supply and speaker do I need to have on hand before this board will work?

You must provide a 6–12 V DC source capable of several amps and a mono speaker wired to the onboard horn socket.
