Small green circuit board with black and gold terminals, two speaker outputs, and a DC power input

DROK 5W+5W PAM8406 DC 5V Stereo Class D Amplifier Board

SKU CH-P085-ZMSVS

Delivers 5W per channel into 2Ω from a 5V supply using a PAM8406 Class D chip with reverse-polarity, short-circuit and over-heat protection

  • Type2001711002
  • Weight0.04 lb
  • Package Contains1
  • DC 5V operation powers compact DIY speaker projects
  • 5W+5W stereo output drives two channels from a single board
  • Over 90% efficiency reduces heat in small enclosures
  • Built-in reverse, short-circuit and over-heat protection safeguards the module
  • Immersion-gold PCB with premium capacitors ensures clean signal path

Compact stereo amplifier for DIY audio builds

The DROK PAM8406 board delivers 5 W per channel into a 2 Ω load, 3 W into 4 Ω and 1.8 W into 8 Ω from a single 5 V supply. Its 2.0 dual-channel Class D topology suits hobbyists assembling desktop speakers, portable boom-boxes or experimental sound projects.

High-efficiency Class D thermal profile

Quoted efficiency exceeds 90 % with harmonic distortion below 10 %, keeping quiescent current and heat low during typical listening levels. On-board protection covers input reverse-connection, output short-circuit and over-temperature events, while the gold-plated terminals and black immersion-gold PCB aid reliable signal transfer.

Steady output under continuous drive

The module maintains its rated output without thermal throttling as long as the 5 V source can supply adequate current, and the over-heat safeguard activates only if junction temperature exceeds safe limits. A selectable MODE pin lets the designer choose between Class D and Class AB operation, and an external shutdown pin provides low-level mute control for battery-powered designs.

Questions about this item

How do I wire the DC 5V supply to the PAM8406 board without triggering the reverse-connection protection?

Connect positive to the VIN+ terminal and negative to VIN-; the board's input reverse-connection protection will block power if the polarity is swapped, so verify the markings before soldering.

Which onboard capacitors or terminals are most likely to need replacement after extended use?

The large-capacity filter capacitors for each channel and the KEMET speaker capacitors are the components that age fastest; the black copper terminal blocks and gold-plated input terminals are rated for long-term service.

At what output-power level does the over-heat protection engage during continuous operation?

The board delivers 5 W per channel into 2 Ω at 5 V; sustained operation at or near that level will trigger the over-heat protection first, especially in enclosed enclosures.
