Taunoe CH32V203: common questions
What microcontroller does the Taunoe CH32V203 use?
The Taunoe CH32V203 is built around the CH32V203F6P6, from the RISC-V family.
How big is the Taunoe CH32V203 PCB?
The Taunoe CH32V203 measures 26 × 51 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Taunoe CH32V203?
26 components, from 18 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 Taunoe CH32V203 design files?
From the taunoe/Taunoe_CH32V203 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Taunoe CH32V203 design in my own project?
The repository has no license, so all rights stay with taunoe. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Taunoe CH32V203 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.
