CA HiFi digital sound board for Raspberry-Pi for the clearest sound quality
HiFiBerry Digi+ is a high quality S/PDIF audio output card for Raspberry-Pi 3, Pi 2 and A+/B+. It is designed as an additional card connected to the P1 and P5 section of the Raspberry-Pi GPIO (P1 and P5 are now included in the 40-pin GPIO). This card also exists in Digi+Transformer version.
At HiFiBerry, they like Raspberry-Pi, its small size, low consumption and flexibility. However, the sound produced by the card is not really good... the audio interface was not designed to produce high fidelity sound. HiFiBerry allows to add high-quality sound to your Raspberry-Pi. The HiFiBerry card is designed to produce optimal sound quality, so it is an optimal solution for all Pi users who love music. The card is compatible with Raspberry Pi 3, Pi 2, A+, B+ models (but not the old A and B models). The HiFiBerry are available in different models DAC+ (analog output), Digi+ (digital output) and Amp+ integrating an amplifier.
HiFiBerry products plug directly into the GPIO port of the Raspberry-Pi. All cards are supported by the standard Raspbian kernels from the Raspberry-Pi distribution. HiFiBerry is committed to Open-Source software, so that all drivers are available in Open Source and HiFiBerry gladly supports developers who want to use the HiFiBerry in their software
HiFiBerry products are already assembled and there is no need to make welds to use the HiFiBerry card
For us maker in electronics
HiFiBerry had the great idea to make a breakout of GPIO pins. So, even with the connector already welded, it remains possible to connect your sensors, cobbler, etc. Opt for a two-step weld, a first row of 20 PinHeader pins then the second row of 20 pins. Attempting to weld a dual-rank connector will be much more difficult.
You will also find a breakout of:
- The 5V power supply - we advise you not to use it to avoid bringing "noise" on the power supply
- TOSLINK-RECEIVER signals - but we are unable to know if they are exploitable and supported by the HiFiBerry kernel module. See the HiFiBerry forum for more information.
- INPUT - just like the TOSLINK-RECEIVER signal, we are unable to evaluate the scope and interest of this signal. See the HiFiBerry forum for more information.
- The headphone Jack - even if the jack is not supplied and welded, you could easily place one on this emplacement.

Although the hardware is capable of outputting Dolby Digital/DTS, the software must be adapted for supporting it. HiFiBerry will support the developers in their implementation. However, HiFiBerry can't guarantee that this feature will work with specific software... Check with the software developer if the feature is supported. See the HifiBerry.com product sheet.
