NanoSound Amp^2
Amplifier board for Nanosound Player
Small size but high efficiency
The NanoSound Amp^2 is an expansion module for the NanoSound Player, to provide it with an amplification section and benefit from a completely autonomous product.
This amplifier module can be used both as a headphone amplifier and also amplifies your speakers thanks to its high efficiency (5W) and high efficiency (over 90%). Sufficient developed power for a small living room or a large bedroom, for example.
In addition, its power supply is extremely simple since the entire NanoSound Amp^2, NanoSound Player and Raspberry Pi system can be powered via a single Micro USB.
