The Allo Digione interfaces are currently the best digital SPDIF outputs to Raspberry Pi. They connect directly to the RPI by GPIO and provide digital transfer while correcting jitter characteristic of a bare SBC.
Armature now offers its excellent USB SPDIF XMOS interface in a simplified version, but always very powerful, allowing to propose it at a contained price. An excellent digital interface with a very good quality / price ratio!
Following numerous requests, we decided to market a digital interface for the Raspberry PI A+ B+ and 2.0 (HAT format). This version is delivered with an IR (infrared) cell and a connector dedicated to the GPIO.
This module converts a stereo balanced signal into a stereo unbalanced signal. The input and output connections are simply made on screw terminals. To carry out this conversion, the module uses on each channel a differential amplifier SSM2151 and an operational amplifier NE5534P in order to effectively limit the generated noise.
This pair of modules converts a balanced signal on XLR input to an unbalanced signal on XH 2.54mm output. A second input is also available in RCA format, with a switch to simply select the active input.
This extremely versatile digital interface module is equipped with an AK4137EQ AKM Sampling Rate Converter (SRC) chip at the heart of its architecture. This chip supports high sampling rates up to 32bit 768kHz in PCM and up to DSD256.
This HAT format digital interface module for Raspberry Pi integrates a DAC AKM AK4137EQ chip supporting high sampling rates: PCM up to 32bit 384kHz and DSD up to DSD256. The audio signal is recovered in I2S from your Raspberry Pi.
This digital interface module integrates an AKM AK4137EQ chip supporting high sampling rates: PCM up to 32bit 384kHz, DSD up to DSD256 and DoP. This chip also allows PCM to DSD, DSD to PCM, DoP to PCM, DoP to PCM and DoP to DSD conversions.
This WM8804 interface with DSP XilinX allows you to transform an I2S signal with MCLK to a classic SPDIF signal on a 75 Ohm BNC connector.Strong point:Low jitter Transformer 75 ohm Pulse output pulse BNC and optical Toslink SPDIF output

This very small module eliminates common ground noise from an audio system. Operating at 12V, it is particularly well suited for Car Audio use. If its installation between the source and the amplifier is extremely simple, the noise reduction provided is important and will allow you to improve the reproduction of your audio system.
This digital input/output selector module allows 4 I2S sources to be directed to one I2S output. It provides a most flexible solution with its integrated microcontroller for the selection of each input switchable by a simple monostable button (sold separately).
