## Overview

The PAM8406 digital amplifier board is a compact, lightweight Class D stereo amplifier delivering 5W per channel at 5V input. Featuring excellent noise suppression, independent channel volume control, and a unique non-LC filter design, it’s optimized for low heat dissipation and efficient USB power use. Ideal for DIY audio enthusiasts seeking high-quality sound in minimal space.

## Description

Product parameters: 1. Ultra volume: 23 x 24 mm. Weight: 0.5g 2. Excellent noise suppression, you will hear any noise without connecting input audio. 3. Dual channel stereo, only need 5V power supply can input 5W+5W, can drive 4Ω, 8Ω small speaker directly, with large output power, sufficient power, superior quality and left right channel volume adjustment. 4. The unique class D digital power board with non-LC filter, can be used computer USB to charge. 5. Double panel wiring, can correctly solve the ground potential balance and cross-channel crosstalk caused by wiring. 6. Super small design, can be easily placed in a variety of digital products within a small space. 7. Machine used to weld the entire plate. 8. Rated operating voltage is 2.5-5V, limited operating voltage is 5.5V. Note: The "negative" of the left and right channel output port cannot be connected together, otherwise it will damage the IC, you must connect the speaker before charging.

Review: Product is very good and both the boards are working well. I couldn't test the boards before so now I tested them on 8 ohms speakers and 5 Volt regulated suppy and although the sound output is low (0.5 watts per channel approx) the sound quality is good. The Ic gets warm after sometime because it's configured in class AB mode instead of D mode which has to changed to class D mode for less heat dissipation by connecting pin 9 of the Ic to positive of power supply instead of ground according to datasheet of this Ic pam 8406. Highly recommended for Diy enthusiasts who want to make a Diy sound system for computers or cellphones
Review: Good. Little heating but ok

### ⭐⭐⭐ Review

The PAM8406 amplifier IC can generate a significant amount of heat when operating at higher power levels, and this heat can cause the amplifier board to malfunction or even fail. Therefore, adding a heatsink to the PAM8406 amplifier board can help dissipate the heat generated by the IC and improve the overall thermal performance of the amplifier. suggest to the seller that they offer the option to purchase the board with a heatsink included in the future, as this may be helpful for other customers who may also encounter similar heating issues.
