What boards using the CH552E are built for
CH552E: common questions
Where can I find a CH552E reference design?
Each of the 5 boards on this page is a real design using the CH552E. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the CH552E use?
Most are built on WCH CH32/CH55x (2), FPGA (2) and STM32 (1).
How big is a typical board using the CH552E?
The median is 28.6 × 13.5 mm, and 40% are two-layer designs.
What is the most popular open source board using the CH552E?
By GitHub stars, Mta1-usb v1 by tillitis, with 3 stars.
Can I simulate one of these boards using the CH552E before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
