RISKYKVM: common questions
What microcontroller does the RISKYKVM use?
The RISKYKVM is built around the CH32V203C8T6, from the RISC-V family.
How big is the RISKYKVM PCB?
The RISKYKVM measures 24.9 × 35.6 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the RISKYKVM?
19 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the RISKYKVM design files?
From the arkadiuszmakarenko/RISKYKVM repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the RISKYKVM design in my own project?
The repository has no license, so all rights stay with arkadiuszmakarenko. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RISKYKVM 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.
