Development board ch552: common questions

What microcontroller does the Development board ch552 use?

The Development board ch552 is built around the CH552T, from the WCH CH32/CH55x family.

How big is the Development board ch552?

The Development board ch552 measures 32.5 × 15.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Development board ch552?

10 components, from 8 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 Development board ch552 design files?

From the ricelectric/development-board-ch552 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 Development board ch552 design in my own project?

Yes, under the terms of its MIT license, which ricelectric chose for the repository.

Can I test firmware for the Development board ch552 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.
