Audio: common questions
What microcontroller does the Audio use?
The Audio is built around the CH32V003JxMx, from the RISC-V family.
How big is the Audio PCB?
The Audio measures 27.8 × 22.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Audio?
38 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Audio design files?
From the byrantech/laptop repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Audio design in my own project?
Yes, under the terms of its MIT license, which byrantech chose for the repository.
Can I test firmware for the Audio 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.
