A DAC board for Raspberry Pi that allows beginners to advanced users to enjoy high-resolution audio!





Product Summary









The popular high-resolution DAC board is back with a commentary!





The "High-Resolution DAC Expansion Board", a product linked with the Raspberry Pi magazine that was very well received at the time of its release, is back with a web commentary! It is an extremely high-performance expansion board, such as high-quality audio produced by the PCM5122, various displays using a color TFT display, and remote control support. The software prepared for this product can be used as it is in the linked article. You can enjoy the network audio function, etc., taking advantage of the network system functions that the Raspberry Pi is good at. It is also possible to further improve the sound quality by installing an external clock board (available as an option). In addition, on the web explanation page newly prepared for the renewal, you can thoroughly explain everything from assembly to a series of actions! Beginners will also be guided to the playback of the sound source. Two types of products are available: pre-assembled / kit. It will satisfy both those who want to touch the player part immediately and those who want to thoroughly enjoy electronic work. With this board, you can turn your Raspberry Pi into a high-performance high-resolution DAC.





This product is a renewal model of a product that was born in a joint project with the April 2018 issue of Raspberry Pi Magazine.





In Mook, more polite and easy-to-read high-quality detailed commentary articles are posted. https://www.nikkeibp.co.jp/atclpubmkt/book/18/267000/





Release of external system clock option board!





ADRPM1801C_SUB-TR33




This is an external system clock board that can fully demonstrate the capabilities of the ADRPM1801P/K. Kyocera's "KC7050K", which has a good reputation among audiophiles, is used as the crystal oscillation module. By combining this board, it is possible to supply the system clock signal to the high-resolution DAC and aim for higher performance and higher sound quality. .
