OSA Electronics DACBerry 400 S

The DACBerry 400 is the first accessory available for the Raspberry Pi 400 that provides audio capabilities. It is the first accessory designed specifically for the Raspberry Pi 400?s all-in-one computer format.

The DACBerry 400 range is a high-resolution soundcard with gold platting and matte black finish. It fits discretely onto the back of the Pi400, avoiding clutter of cables and fixtures used with other possible solutions. It is also usable with Raspberry Pi boards, plugging directly onto the GPIO header.

With no analogue outputs of its own, the Raspberry Pi relies on HAT (Hardware Attached on Top) expansion modules to provide features such as audio input/output. With up to two 3.5mm jacks across two versions of the product, DACBerry 400 supports both audio out (headphones, line-out) and audio in (MIC). The DACBerry 400 connects to the Raspberry Pi 400?s 40-pin GPIO header and provides pass-through for further expansion.

It suites all users from beginners to professionals. Just connect your DACBerry 400 to desired powered speakers or to an audio amplifier and you can be up and running quickly, enjoying flawless high-quality audio playback.

It integrates a 96kHz/32bit DAC chip with hardware volume control, allowing you to play/record your files digitally. Outputs are line level headphone over 3.5mm jack cable. The DACBerry 400 uses the I2S interface for its audio input which reduces CPU load on the Raspberry Pi compared to USB solutions. It is powered directly from the GPIO header so no extra cables or power supplies are needed, keeping all USB ports on the Pi 400 free for other uses.

The software-configurable DACBerry 400 fits easily into the Raspberry Pi ecosystem. It uses an integrated DSP to create 3D effects including equalisation and de-emphasis. This is complemented by a DAC with 102dB SNR and ADC with 92dB SNR. The low-noise design partitions the analogue and digital functions to achieve THD+N @ 1kHz of 0.003%.

The Raspberry Pi 400 has become extremely popular with younger makers, providing a low-cost, all-in-one computing solution. Adding audio in/out will bring a new dimension to that experience and will help retro gamers, coding clubs, schools and hobbyists to discover even more application areas. No soldering is required, it?s simple to install and use, connect your DACBerry 400 to a set of speakers, headphones or an audio amplifier and enjoy crystal-clear high-quality audio playback.
