OKdo has added the DACBerry 400 audio input/output to the Raspberry Pi ecosystem. It has been produced in partnership with OSA Electronics, especially for the Raspberry Pi 400, and is offered exclusively through OKdo.
The device is claimed to be the first accessory available for the Raspberry Pi 400 that offers audio capabilities. OSA Electronics contributed the design expertise and manufacturing support. It complements its existing product line-up of audio accessory HATs for the Raspberry Pi format but is the first and only accessory to be devised specifically for the Raspberry Pi 400’s all-in-one computer format.
With up to two 3.5mm jacks over two versions of the product, it supports both audio out (headphones, line-out) and audio in (MIC, line-in). The device connects to the Raspberry’s 40-pin GPIO header and gives pass-through for further expansion.
“We have designed the DACBerry 400 jointly with OKdo, 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.”
With a sample rate of up to 96kHz at 32-bit, the device employs 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 accomplish THD+N @ 1kHz of 0.006%.
“Providing the best possible entry into coding is important to OKdo,” said Richard Curtin, OKdo’s SVP 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.”
