Iw18ch32v003: common questions
What microcontroller does the Iw18ch32v003 use?
The Iw18ch32v003 is built around the CH32V003FXPX, from the RISC-V family.
How big is the Iw18ch32v003 PCB?
The Iw18ch32v003 measures 100 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Iw18ch32v003?
120 components, from 22 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 Iw18ch32v003 design files?
From the frytkisasmaczne/iw18ch32v003 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 Iw18ch32v003 design in my own project?
The repository has no license, so all rights stay with frytkisasmaczne. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Iw18ch32v003 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.
