Raspberry Pi: adding audio to enhance opportunities for its users

Raspberry Pi 400

OKdo has added the DACBerry400 audio input/output to the Raspberry Pi ecosystem, developed in partnership with audio accessory provider OSA Electronics specifically for the Raspberry Pi 400.

The DACBerry 400 is the first accessory, providing audio capabilities for the Raspberry Pi 400, opening a whole new window of opportunities and uses for the DACBerry 400.

With no analogue outputs of its own, it relies on hardware attached on top expansion modules to provide features such as audio input/output. OSA Electronics has used its experience in this area to develop the DACBerry 400.

With up to two 3.5mmjacks across two versions of the product, it supports both audio out (headphones, line-out) and audio in (MIC, line-in). The DACBerry 400 connects to the Raspberry Pi 400’s 40-pin GPIO header, providing pass-through for further expansion.

With a sample rate of up to 96kHz at 32-bit, the DACBerry 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.

“We have designed the DACBerry 400 jointly with ODdo, using the latest audio technology and best design practices,” commented Oriol Sanchez, Founder OSA Electronics.

“We’re sure it will become a must-have accessory for Raspberry Pi 400 users, meeting their high expectations for audio capabilities.”

It is no secret that the Raspberry Pi 400 has become extremely popular amongst younger makers and engineers, providing a low-cost, all-in-one computing solution that is easy and fun to program, with unlimited opportunities.

Adding audio in/out will bring a new dimension to that experience and will help retro gamers, coding clubs, university students, schools, and hobbyists to discover even more application areas.

“Providing the best possible entry into coding is important to OKdo,” said Richard Curtin, Co-Founder and SVP at OKdo.

“That’s why we worked with OSA Electronics to bring the DACBerry 400 to market, extending the product offering by making it fun and easy for those new to coding to add audio to their projects.”
