Audiophonics DigiPi +

Digital interface for Raspberry Pi AES / EBU & Optical

Interface digipi plus

Warning: this interface needs a Raspberry Pi 3B / 3B + to run. This piece is not provided.


This interface extends the capabilities of your Raspberry Pi by adding a range of digital audio output. It includes an optical output (SPDIF) with a connector already mounted, a coaxial output (SPDIF, this one has to be mounted with an RCA connector - not included) and an AES / EBU XLR already mounted with a Neutrik connector. Tnaks to DigiPï + interface and a software solution (Volumio for example) your Raspberry Pi can become a true high-fidelity network drive.

The interconnection between your Raspberry Pi and digital interface is directly I2S-based for increased performance and respect of the audio signal. This type of protocol limits indeed the need for successive signal conversions and manages high sampling rate (up to 192kHz).

The DigiPi + is compatible with multiple softwares (PiCore, Volumio, Moode...etc)  thanks to HiFiBerry Digi Driver. Those are free xtremely comprehensive software solutions based Raspberry Pi with many features to enrich playback and potentiate the rest of your audio system. This software environment has been developped especially for this type of hardware and each part will be able to function to the best of its potential.

To operate correctly, the DigiPi+ needs to use the HiFiBerry Digi and Digi+ driver.

DigiPi+ Driver

AES / EBU on Raspberry Pi

This digital interface is one of the few on the SBC market to offer an AES / EBU XLR output. This greatly opens the possibilities of integration regarding solutions based on RPI. It is a good way to associate your player / mediacenter with very advanced devices favoring AES / EBU standard.

Naturally, the DigiPi + also loads traditional digital connectors rigor, as a SPDIF Optical. The circuit is also provided in order to connect an input coaxial SPDIF connector if necessary. However, a RCA connector is needed to enjoy it ..

0.5ppm TCXO electronic clock

WM8804G & Clock TCXO Interface

The interface works with a digital chip WM8804G. It is connected to a Raspberry Pi via I2S GPIO and accuracy of the digital stream is provided by a 27MHz TCXO clock Audiophonics 0.5ppm.

With this configuration, the interface is capable of handling sample rates up to 24bit / 192kHz with a distortion rate and minimal jitter (50ps).


A power supply that suits your needs

To give you the whole attitude to make the best decision in terms of power supply, DigiPi + interface can comply with different power configuration.

We can therefore supply the interface and the Raspberry Pi via Jack 5.5x2.5mm DC input. The opposite is equally feasible and can interface will be powered by the Raspberry Pi via GPIO.

A third configuration is to use two alimenations simultaneously. Each element (DigiPi + and Raspberry Pi) is powered independently, which considerably limits the food-related interference.
