Usb charging hub: common questions

What microcontroller does the Usb charging hub use?

The Usb charging hub is built around the RP2040, from the RP2040/RP2350 family.

How big is the Usb charging hub PCB?

The Usb charging hub measures 80 × 95 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Usb charging hub?

206 components, from 51 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb charging hub design files?

From the tobycm/usb-charging-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 charging hub design in my own project?

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

Can I test firmware for the Usb charging hub without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
