Raspberry Pi 400 with audio I/O is exclusive to OKdo
In partnership with audio accessory provider, OSA Electronics, OKdo, an Electrocomponents company, has developed the DACBerry 400 audio I/O specifically for the Raspberry Pi 400.
The DACBerry 400 is the first accessory available for the Raspberry Pi 400 that provides audio capabilities says OKdo. OSA Electronics provided the design expertise and manufacturing support for the project which complements its existing range of audio accessory HAT (hardware attached on top) expansion modules for the Raspberry Pi format. The DACBerry 400 is claimed to be only accessory to be designed specifically for the Raspberry Pi 400’s all-in-one computer format.
Raspberry Pi has no analogue outputs of its own and relies on HAT expansion modules to provide features such as audio input/output. There are two versions of the DACBerry 400 available with up to two 3.5mm jacks to support 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 and provides pass-through for further expansion. A protective cover will also be available.
The software-configurable DACBerry 400 fits easily into the Raspberry Pi ecosystem. With a sample rate of up to 96kHz at 32-bit, it uses an integrated DSP to create 3D effects including equalisation and de-emphasis. This is complemented by a DAC with 102dB signal to noise ration (SNR) and ADC with 92dB SNR. The low-noise design partitions the analogue and digital functions to achieve thermal harmonic dynamics (THD)+N at 1kHz of 0.006 per cent.
The Raspberry Pi 400 has become extremely popular with younger makers, providing a low-cost, all-in-one computing solution that is easy and fun to program. 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.
“Providing the best possible entry into coding is important to OKdo,” said Richard Curtin, OKdo’s senior vice president of technology. “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.”
The DACBerry 400 Model S is available now at OKdo.com. The Model M with two 3.5mm jacks and case is launching October.
