DSD BOARD
About the DSD BOARD
DSD BOARD is an open source PCB design by ERDALECE, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 100 × 65 mm, with 207 components from 12 distinct parts.
Other key parts include the 74AHC595. By type, the board carries 140 resistors, 34 capacitors, 16 ICs, 16 inductors and 1 connector.
It belongs with the audio and displays & leds designs in this gallery.
From the project
ZeyBack R2RDAC
High-performance DIY USB Audio / FPGA based R-2R DAC platform.
The STM32H750 MCU plays audio in 44.1 kHz - 768 kHz PCM and DSD64 - DSD512 DSD (DoP) formats.
Optionally, a second USB audio input can be added by connecting an XMOS or AMANERO.
SPDIF audio input up to 192 kHz is possible via the CS8416 or directly through the FPGA input.
It has one coaxial and two optical inputs.
