About the Phonkyo PCB

Phonkyo is an open source PCB design by fabiomsouto, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 65 × 30 mm, with 31 components from 21 distinct parts.

Other key parts include the CAT24C256, PCM5102A and XC6206P332MR. By type, the board carries 14 capacitors, 10 resistors, 3 ICs, 3 connectors and 1 diode.

It belongs with the audio designs in this gallery.

From the project

Phonkyo, be lazier!

A PiHat for Onkyo RI-enabled devices, hence the name (PiHat Onkyo).

Phonkyo makes a Raspberry Pi behave like one of Onkyo's own docks. Onkyo receivers have a small RI (Remote Interactive) jack on the back, which docks use to switch the receiver on and change it to the dock input. Phonkyo speaks the same protocol, so when you start playing music the receiver comes on and selects DOCK by itself, and after a few minutes of silence it switches off again.
