PIANO Hi-Fi DAC Shield has been designed for those seeking audio perfection. Every detail has been thought of!

First we start with 4 LDOs, one & two for the analog (avcc), the third for the digital (dvcc) and the fourth for the headphone amplifier.

Then we used film capacitors and thin film resistors in the audio path. All brand names (Vishay, SRcap, Stackpole...). Finally, our PCB has very good partitioning for digital and analog section.

If you understand all of the above, great! That means that you are an audiophile. If not, don’t worry… Just listen to the PIANO music!

PIANO houses a headphone amplifier based on the TPA6133A2 chipset and 3.5mm phone jack.
