About the PicoDAC PCB

PicoDAC is an open source PCB design by Person-0, published on GitHub. It is a 4-layer board measuring 35.1 × 58.3 mm, with 42 components from 16 distinct parts.

Other key parts include the CS43131-CNZR, PCA9306DCUR, SN74AXC4T245PWR, XTPS7A2018-XC and 74AHCT1G125GV. By type, the board carries 18 capacitors, 9 LEDs, 9 resistors, 5 ICs and 1 connector.

It belongs with the audio designs in this gallery.

From the project

A USB-C to 3.5mm HiFi mini DAC

The main PCB case also requires this 2.5X8 screw that will be used to attach the detachable part with the non-detachable part.

As for the case of the board - 2, since it really is just two directly connected USB-C plugs, the top and bottom part of the case will be glued together after seating the board-2 PCB inside it properly (after testing it).

All the design files are available in the CAD folder. Exported STEP files for 3d-printing are available in /CAD/exports.
