Sending this design for peer review? Begin with the layout handover report and REVIEWERSTARTHERE.md, then use the schematic, placement, and command-line visual inspection guides. The findings template records actionable review results against one Git commit.

The functional-ECO placement baseline is a separate 120 × 100 mm review board made from explicit hand-selected coordinates. It includes the readback, J702 TVS and I/V A/B-channel schematic ECO, a tighter DAC bypass row and the local J702 TVS branches. The integrated audio study is the current routing review candidate; the newer DAC/core…

DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY: common questions

What microcontroller does the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY use?

The DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY is built around the CH32V307RCT6, from the RISC-V family.

How big is the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY PCB?

The DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY measures 120 × 100 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY?

480 components, from 122 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY design files?

From the ooyang0325/Hi-Res-DAC repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY design in my own project?

The repository has no license, so all rights stay with ooyang0325. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the DAC HPA 120x100 INTEGRATED AUDIO STUDY ONLY without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
