1 Name Amplifier DIY Electronic Kits
2 Model AKE-1
3 Operating Voltage DC 4.5-5V
4 PCB Size 42*31mm

Features:
1. Adopt PAM8403 as power amplifier chip. PAM8403 belongs to D class audio power amplifier, and it supply 3W power with more than 85% efficiency.
2. Large magnet loudspeaker.
3. Most capacitors adopt monolithic capacitors, and they have good stability, low temperature drift, low equivalent DC resistance, long service life.

Notice:
1. Because the output current of computer USB port, if plug it on PC for power supply, once adjust the volume or the bass is strong, the sound quality will be bad.
   Please use independent USB power (output more than 1A) to supply power for the sound box.
2. Since the digital volume control has high gain, please do not input too large signal then generate limit cutting, or the sound will be distorted.
3. If you want to gain better effects, we recommend you use two containers to pack the two loudspeakers.

Perfectly designed with all the parts you could need, including wiring, input and power connectors. Took about 2 hours to build as a training project with someone new to soldering. I will buy more because it's a beautiful kit!
