Usb Dongle: common questions

What microcontroller does the Usb Dongle use?

The Usb Dongle is built around the CH552G, from the WCH CH32/CH55x family.

How many components are on the Usb Dongle?

26 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb Dongle design files?

From the LeoMos10/Usb_Dongle repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Usb Dongle design in my own project?

The repository has no license, so all rights stay with LeoMos10. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Usb Dongle 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.
