CH559-MASS: common questions
What microcontroller does the CH559-MASS use?
The CH559-MASS is built around the CH559L, from the WCH CH32/CH55x family.
How big is the CH559-MASS PCB?
The CH559-MASS measures 59.9 × 19.9 mm, has 4 copper layers and is 1.647165 mm thick.
How many components are on the CH559-MASS?
29 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 CH559-MASS design files?
From the zOnlyKroks/pcb-consortium 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 CH559-MASS design in my own project?
Yes, under the terms of its CC0-1.0 license, which zOnlyKroks chose for the repository.
Can I test firmware for the CH559-MASS without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug WCH CH32/CH55x firmware against it before you order a PCB.
