Mysterio: common questions
What microcontroller does the Mysterio use?
The Mysterio is built around the CH32V003JxMx, from the RISC-V family.
How big is the Mysterio PCB?
The Mysterio measures 38.8 × 34.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Mysterio?
9 components, from 5 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mysterio design files?
From the davedarko/Simple-Add-ons-SAO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mysterio design in my own project?
The repository has no license, so all rights stay with davedarko. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mysterio 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.
