DBR400S, OSA Electronics DACBerry 400 S for Raspberry Pi 400

The DACBerry400 S is the first accessory available for the Raspberry Pi 400 that provides audio capabilities so you can connect to speakers, headphones or an audio amplifier and enjoy crystal-clear high-quality audio playback. 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.
It suites all users from beginners to professionals. Just connect your DACBerry400 to desired powered speakers or to an audio amplifier and you can be up and running quickly, enjoying flawless high-quality audio playback.
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.

The OSA Electronics audio card has high power outputs and programmable microphone bias level. It has headset auto detect and automatic gain control (AGC) for record.
