USB-Hub: common questions
What microcontroller does the USB-Hub use?
The USB-Hub is built around the STM32F103CBT6TR, from the STM32 family.
How big is the USB-Hub PCB?
The USB-Hub measures 72 × 65.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the USB-Hub?
102 components, from 49 distinct parts. The full bill of materials is listed on this page.
Where can I download the USB-Hub design files?
From the SalihAyvaci21/USB-Hub repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the USB-Hub design in my own project?
The repository has no license, so all rights stay with SalihAyvaci21. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the USB-Hub without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
