## Description

5W*5W Class D Digital Audio Amplifier Board Parameters: Working voltage: DC 5V (please don't use more than 5V, or the IC will be burnt) Output power: 5W 2Ω 5V \ 3W 4Ω 5V \ 1.8W 8Ω 5V Input method: single-ended Dimension: 55.12*32.26mm Performance: Efficiency: >90% General harmonic distortion & Noise: <10% Low quiescent current Noise suppression The protection：against reverse connection of power input; Short circuit; Overheat; EMI is allowed to pass Additional function: 1. Available to connect amplifier type to choose the different function (MODE: high electricity level is Type D, low electricity level is Type A, B. Factory defaults high electricity level) 2. Available to add an external Shutdown (SD: the chip will be Shutdown at low electricity level, factory defaults high electricity level 3. Available to add a Mute (the chip will be in mute mode when low electricity level, factory defaults high electricity level) Package includes: 1 X 5W*5W Class D Digital Audio Amplifier Module

Review: Lo usé para un proyecto escolar con arduino y funcionó a la perfección
Review: Bought this for my gp star proton pack project It has good sound and a nice compact shape which is nice to be able to squeeze in Overall no complaints Many people who were using this for the same project had a issue with noise Putting a diode in series with the negative or ground connection for this unit will eliminate that humming or noise if you are powering your sound supplying device from the same power source

## Features

- Parameters: DROK audio amplifier board working voltage is DC 5V, output power is 5W (2Ω 5V)/3W (4Ω 5V) / 1.8W (8Ω 5V). Input method is monaural input.
- Artificial Material: this New-designed mini power amplifier is made of noble black immersion gold circuit board, imported KEMET speaker capacitor, large-capacity filter capacitor for channels. Besides, we customized black copper terminal blocks and gold-plated audio input terminal blocks for this new amplifier module.
- High Performance: the digital amplifier module is with high efficiency of over 90%, general harmonic distortion noise is less than 10%, low quiescent current and noise suppression.
- Safe Protection: the class D dual-channel amp board is designed with input reverse connection protection, short circuit protection, over heat protection; what's more, EMI is allowed to pass.
- Additional Function: it is available to connect amplifier type to choose different function (MODE: high electricity level is Type D, low electricity level is Type AB. Factory defaults high electricity level); available to add an external Shutdown (SD: the chip will be Shutdown at low electricity level, factory default high electricity level.

## Questions & Answers

**Q: What’s the knob shaft dimensions for cutout**
A: diameter 6mm =0.235'', length 10mm =  0.41''

**Q: What kind of battery can you power this with?**
A: Mine has been playing continuously for an hour and ten minutes (so far) using a 3.7 volt LiPo battery.
Battery was almost fully charged (4.1 volts) and is powering this little amp and a  bluetooth receiver in a vintage tabletop radio converted into a bluetooth speaker.
I would imagine this amp could also be powered by a single 18650 li-on battery

**Q: Does it come with the knob shown in the picture**
A: Yes.  The knob is a power switch and volume control.

**Q: What is the difference between this model and the discontinued dk-amp30w model? thank you!**
A: I believe it is an upgraded design from the last board.
