Euroknob: common questions
What microcontroller does the Euroknob use?
The Euroknob is built around the CH32V003FxPx, from the RISC-V family.
How big is the Euroknob PCB?
The Euroknob measures 24 × 79 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Euroknob?
23 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Euroknob design files?
From the mitxela/euroknob repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Euroknob design in my own project?
The repository has no license, so all rights stay with mitxela. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Euroknob 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.
