CH32V3 CoreBoard: common questions
What microcontroller does the CH32V3 CoreBoard use?
The CH32V3 CoreBoard is built around the LQFP-100_14x14mm_P0.5mm, from the RISC-V family.
How big is the CH32V3 CoreBoard PCB?
The CH32V3 CoreBoard measures 38.3 × 25.2 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the CH32V3 CoreBoard?
53 components, from 24 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 CH32V3 CoreBoard design files?
From the ErBWs/CH32-Bike-Overland 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 CH32V3 CoreBoard design in my own project?
Yes, under the terms of its GPL-3.0 license, which ErBWs chose for the repository.
Can I test firmware for the CH32V3 CoreBoard 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.
