We love the Raspberry Pi for its small form factor, its low power consumption and its flexibility. However, unfortunately the onboard sound output is not designed for high fidelity sound (also not the model B+ and the Raspberry 2B). HiFiBerry adds high-quality sound to your Raspberry Pi. Our sound cards are designed for optimal sound output quality. It is the ideal solution for all Raspberry Pi users that love music. Our boards are compatible with almost all Raspberry Pi models. For the old Raspberry Pi A/B we offer the HiFiBerry DAC and Digi, for the newer model A+/B+ and 2B you can use our HiFiBerry DAC+, Digi+ and Amp+. If you are not sure what is the right product for you, have a look at the product comparison matrix. HiFiBerry products connect directly to the Raspberry Pi, no external cabling is needed. All boards are supported in the standard Raspberry Pi kernel that is included in the Raspbian distribution. We are committed to Open Source software. All drivers are available as open source, we support developers to use our products with their software. The HiFiBerry products are already assembled and do not need soldering on the HiFiBerry board. On the new Raspberry Pi model A+ and B+ and 2B, you just plug the HiFiBerry board onto the Raspberry Pi. All necessary material is included. On older Raspberry Pi model A/B, a small 2Χ4 pin header must be soldered onto the Raspberry Pi.
