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…

The KiCad project lives in the ooyang0325/Hi-Res-DAC repository on GitHub; these links point at the commit this page was built from.

DAC-HPA — 100 × 80 comparison placement: common questions

What microcontroller does the DAC-HPA — 100 × 80 comparison placement use?

The DAC-HPA — 100 × 80 comparison placement is built around the CH32V307RCT6, from the RISC-V family.

How big is the DAC-HPA — 100 × 80 comparison placement PCB?

The DAC-HPA — 100 × 80 comparison placement measures 100 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DAC-HPA — 100 × 80 comparison placement?

470 components, from 119 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 — 100 × 80 comparison placement 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 — 100 × 80 comparison placement 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 — 100 × 80 comparison placement 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.
